V) Optical Fibers and Cables Core leaders in optical fibers and cables: YOFC, Hengtong Optic-Electric, ZTT, FiberHome, Yongding Shares The value of the optical fiber and cable industry chain presents a pyramid structure. The upstream (optical fiber preform) has the highest technical barriers, the midstream (fiber drawing/cable assembly) is the manufacturing core, and the downstream is application services. Major manufacturers include YOFC, Hengtong Optic-Electric, ZTT, FiberHome, Yongding Shares, Tongding Interconnection, Tefa Information, Kingsignal, Huamai Technology, Shijia Photons, Orient Cable, etc. YOFC:A globally leading provider of optical fiber preforms, optical fibers, optical cables, and comprehensive solutions.

It does not need to convert optical signals into electrical signals and then back again; it can directly let optical signals find the correct path. Its working principle is very much like adjusting a set of parallel mirrors—when a mirror rotates by an angle, the reflected light shifts accordingly, precisely controlling the direction of the optical signal. This technology solves the delay and high energy consumption problems caused by signal conversion. Its theoretical efficiency is 1000 times that of traditional electrical switches, while power consumption is only one-tenth. It is particularly practical for ultra-large-scale data centers with high electricity cost proportions and has become the preferred choice for next-generation data center networks. Currently, leading domestic OCS complete machine and integration enterprises are as follows: IV. Outlook for the Optical Communication Industry Summary of the five major links in the optical communication industry chain The optical communication industry is standing at a historic inflection point of AI computing power explosion and digital infrastructure upgrading. It is comprehensively evolving from a traditional "communication pipe" to the "nervous system" of the AI computing power era. The next five years (2026-2030) will be a "golden development period" for the optical communication industry. The industry will present four core trends: "demand explosion, technology iteration, pattern reconstruction, and domestic substitution." At the same time, the structural contradiction of shortage of upstream core materials is also relatively prominent. In August 2026, the Ministry of Industry and Information Technology issued the "14th Five-Year Plan for the Development of the Information and Communication Industry," proposing to strengthen R&D of ultra-high-speed large-capacity optical transmission, optical access, and submarine cable optical communication technologies, accelerate R&D and application of new fiber technologies such as hollow-core fiber, and carry out research on industry-integrated application technologies such as automotive optical communication and industrial control optical networks. Promote R&D of large-capacity and high-bandwidth optical communication equipment, focus on building 1.6Tb/s optical transmission systems, 200G-PON optical access systems, hollow-core fiber optic cables and other ultra-large-capacity all-optical bearer products, and accelerate R&D of 100G and above high-speed inter-satellite and satellite-ground optical communication equipment. The Ministry of Industry and Information Technology has issued the 14th Five-Year Plan for the Development of the Information and Communication Industry. (I) Demand Explosion: AI Computing Power + Network Bandwidth Demand AI computing power demand becomes the core engine: The explosive growth of AI large models is driving the explosive growth of GPU clusters and ultra-large-scale data centers (IDCs). AI optical modules (such as 800G and 1.6T) have become the main demand force. The AI optical communication market space is expected to maintain a compound annual growth rate of more than 40%, and is expected to exceed US$90 billion by 2030. Upstream core links are in short supply: Supply and demand are mismatched in core links such as optical chips and indium phosphide substrates. The global supply-demand gap for EML optical chips required for optical modules exceeds 30%. Long expansion cycles: Optical fiber preform technology has high barriers, and the expansion cycle is as long as 18 to 24 months. The short-term supply shortage pattern is difficult to reverse. Network bandwidth demand is growing: The digital economy and AI are driving a surge in global data traffic, creating increasing demand for network bandwidth. The optical transmission equipment market will grow steadily. According to Omdia data, the global market size in 2024 was US$16.7 billion, and it is expected to grow by 4.2% annually from 2024 to 2029, reaching US$20.5 billion by 2029. The global optical transmission equipment market will reach US$20.5 billion by 2029. (II) Technology Iteration: CPO + Silicon Photonics Integration + Automotive Optical Communication + Hollow-Core Fiber Technology Continuous rate iteration: Optical modules are accelerating from 800G to 1.6T and 3.2T rates. CPO (co-packaged optics) technology entered the stage of large-scale mass production in August 2026. Silicon photonics integration breakthrough: Silicon photonics integration technology has become the key to breaking through the performance bottleneck of traditional optical chips. China's first 8-inch silicon photonic chip mass production line is expected to be completed within 2026. Emerging scenarios landing: Automotive optical communication is rising with the development of L3 autonomous driving. The global automotive optical fiber network market is expected to reach US$3.13 billion in 2026. Frontier material positioning: Next-generation transmission media such as hollow-core fiber are gradually achieving industrialization. Latency is reduced by nearly half compared with traditional optical fiber, making it a new high ground for technological competition. (III) Pattern Reconstruction Differentiation between datacom and telecom demand: The growth rate of the datacom market (intra-data center interconnection and inter-data center interconnection) far exceeds that of the telecom market (5G/6G bearer networks and fixed network upgrades). Demand for optical interconnection in data centers is growing exponentially, and fiber usage per rack is soaring. The industry is shifting from "oversupply" to a "fiber famine." Fiber volume and price rise together: In 2026, the global fiber supply-demand gap rate is about 16.4%. Prices of high-end specialty fibers have risen sharply, and the industry has entered a seller's market where goods are hard to obtain. Market scale expansion: In 2026, the global optical module market size is expected to reach 201.6 billion yuan, and China's optical module market size will reach 56.4 billion yuan. Application scenarios continue to broaden: Industry boundaries are extending to emerging fields such as satellite internet (low-orbit satellites), quantum communication, and integrated sensing, communication, and computing, opening up new incremental space for optical communication. (IV) Domestic Substitution Optical fiber preform field: Leading enterprises such as Hengtong Optic-Electric and YOFC continue to expand production. Cross-border player Han's Laser has also entered the hollow-core fiber direction with 2.52 billion yuan. Optical chip and optical module field: Source Photonics, a subsidiary of Dongshan Precision, is investing 8.1 billion yuan to expand optical chip and optical module capacity. Shijia Photons plans to raise 2.8 billion yuan through a private placement for high-speed optical chip development. Upstream materials field: Xiandao Technology Group is investing 12 billion yuan to build an indium phosphide substrate industrialization base. Domestic substitution rate needs improvement: Optical chips at 10G and below have achieved domestic substitution, but the domestic substitution rate for high-speed active optical chips at 25G and above is still relatively low. In summary, the future prospects of optical communication are broad, with a trillion-yuan market that can penetrate every aspect of development, covering AI, data, industry, healthcare, and more. Application scenarios such as data centers, telecom networks, data center interconnection, industrial internet, intelligent driving, quantum communication, smart grids, satellite communication, fiber sensing, and aerospace all rely on optical communication to achieve high-speed and stable data transmission and are drivers of demand growth.

Kinghelm General Manager Song Shiqiang at 2026 Shanghai Munich Electronics Show W5.317 In 2026, Kinghelm (www.kinghelm.net) officially entered the optical communication field. General Manager Mr. Song Shiqiang emphasized: "Optical communication covers the entire industry chain of optical chips, optical devices, optical modules, optical fibers and cables, and system equipment. It is a core rigid-demand track for major projects such as 5G/6G data centers and the East Data West Computing project. The dual-wheel drive of technological iteration and market demand is very pronounced, because its core demand has rapidly shifted from traditional operator public network construction to emerging scenarios such as AI data center interconnection, industrial optical private networks, and automotive optical interconnection, and is deeply bound to new demands such as computing power networks and AI large models. Advanced packaging and silicon photonics integration technologies have become core breakthrough directions. In 2026, China has listed high-end optoelectronic chips, CPO co-packaged optics, all-optical switching and other core technologies as key research directions. There is broad space for domestic substitution in optical communication. Kinghelm (www.kinghelm.com.cn), as an original technology manufacturer and an important participant in ‘domestic substitution’, will enter the optical communication field to open a new development track, aiming at the ‘heart’ of the optical communication industry chain. This is the core critical link of domestic substitution, covering transmitter/receiver chips and indium phosphide-based high-speed laser chips." Kinghelm Chief Engineer Mr. Qin Xianghong working In view of this, Kinghelm (www.kinghelm.net) Chief Engineer Qin Xianghong, combining years of deep industry research experience and drawing on the existing research results of predecessors and peers, followed the five main lines of the optical communication industry chain—optical chips, optical devices, optical modules, optical fibers and cables, and transmission equipment—and summarized and compiled "A Comprehensive Summary of the Optical Communication Upstream and Downstream Industry Chain and Analysis of Domestic and Foreign Manufacturers." It will unfold from four aspects: 1. Overview of optical communication – basic principles; 2. Optical communication industry chain – analysis of upstream, midstream and downstream industry chains; 3. Key companies in China’s optical communication industry chain; 4. Outlook for the optical communication industry. This initiative aims to promote information communication, resource sharing, and knowledge co-construction across the upstream, midstream and downstream of the optical communication industry chain, realize industry chain optimization, integration and collaborative innovation, and thereby enhance the global industrial discourse power of Chinese enterprises. Kinghelm "A Comprehensive Summary of the Optical Communication Upstream and Downstream Industry Chain and Analysis of Domestic and Foreign Manufacturers" I. Overview of Optical Communication – Basic Principles (I) Overview of Optical Communication Optical communication essentially uses "light" as the information carrier, and optical fiber is the dedicated high-speed highway. Its core relies on mutual conversion between electrical and optical signals to achieve information transmission. The transmission process is very clear: information initially exists as electrical signals, like packaged goods; the laser chip at the transmitting end is the "conversion station," converting electrical signals into optical signals—just like loading goods onto an optical train and transmitting them along the optical fiber highway; after reaching the receiving end, the detector chip converts the optical signals back into electrical signals, like unpacking the goods so the receiver gets the complete information. Information flow is divided into three steps: birth of optical signals, transmission scheduling, and identification. Key components each have their roles: the optical transceiver unit is the core, managing the generation, adjustment, and detection of optical signals; optical splitters are like traffic signs, AWG, VOA, and optical switches are dispatchers, and optical amplifiers are energy boosters, jointly ensuring smooth transmission. Basic Principles of Optical Communication (II) Full Process of Optical Communication The entire optical communication process is actually like a complete "production line," advancing from beginning to end in the order of "optical chip → optical component → optical module → optical communication equipment → terminal market." The upstream of the chain mainly consists of optical chips (optical communication chips), optical components (optical communication components), and optical modules (optical transceiver modules) as core links. Among them, optical chips are the "source core component" of the entire process, located at the very front, and are also the key to enabling optical components and optical modules. First, optical chips and a series of components are assembled into optical components, then further packaged into optical modules. After that, optical modules are installed into midstream optical communication equipment, and finally these devices are applied in downstream telecom markets, data communication markets, and some emerging markets. Full Process of Optical Communication (III) China’s Optical Communication Industry Optical communication is a communication method that uses light waves as the transmission medium. This field is an important part of China’s implementation of the innovation-driven development strategy and an important development direction in China’s transformation toward a manufacturing power and a science and technology power. The optical communication industry includes multiple links. The stronger discourse power is concentrated at the upstream and downstream ends. Upstream chip manufacturers and downstream customers are relatively strong, while the cost control level of midstream optical module manufacturers determines their overall profitability. According to LightCounting’s global top ten optical module ranking, Chinese manufacturers occupy seven seats, among which Innolight and Coherent are tied for first, HiSilicon ranks fourth, Accelink ranks fifth, Hisense Broadband ranks sixth, Eoptolink ranks seventh, HGTECH ranks eighth, and Source Photonics ranks tenth. II. Optical Communication Industry Chain – Analysis of Upstream, Midstream and Downstream Industry Chains (I) Overview of the Optical Communication Industry Chain The upstream, midstream and downstream of the optical communication industry chain In the upstream, midstream and downstream of the optical communication industry chain, the upstream mainly consists of core component links including optical chips, optical components, and electrical chips; the midstream includes optical devices, optical modules, and optical fibers and cables; the downstream is divided by application scenario into the telecom market and the data communication market. With technological progress and cost reduction, the application scope of optical communication products continues to expand, and market demand continues to increase: Optical chips are III-V compound semiconductor materials that realize photoelectric signal conversion; Optical components mainly include ceramic sleeves/ferrules, optical transceiver interface components, etc. At present, China is the world’s largest production base for optical components, and market competition is fierce; Optical chips and optical components are key elements in manufacturing optical devices: various optical components are processed and assembled to obtain optical devices, and multiple optical devices are packaged to form optical modules; Optical devices are various functional devices made using the electronic conversion effect, and are key and core components of optoelectronic technology; An optical module is an optical device used for high-speed data transmission. Its function is to realize mutual conversion between optical signals and electrical signals, thereby enabling data transmission in communication networks. (II) Upstream Core of Optical Communication: Optical Chips Upstream Core of Optical Communication: Optical Chips In the upstream of the entire optical communication industry chain, the most core link is optical chips. Optical chips are the core components for mutual conversion between optical signals and electrical signals, equivalent to the "power engine" of information transmission. Their performance directly determines the transmission speed of the optical communication system. After integrating and packaging optical chips with a series of supporting components, optical modules with practical functions are formed. Optical chips are the "source core components" of the optical communication industry chain and the key to the normal operation of optical components and optical modules. Whether it is fiber broadband used at home, 4G/5G networks that mobile phones depend on, or data centers storing massive amounts of data, optical chips are crucial. They directly affect the speed of information transmission in these networks and whether they can operate stably without interruption. They are classified according to different standards as follows: Classification of Optical Chips The global optical chip market is growing steadily, becoming the "growth engine" of the optical communication industry. Global data traffic is surging, and all industries need greater bandwidth, which has fueled high-speed optical modules and supporting chips. Among them, high-speed optical chips above 40G run much faster than low- and medium-speed versions. From 2019 to 2025, the proportion of high-speed optical chips above 25G used in data centers and telecom fields has continued to increase. It is expected that 1.6T and even higher-speed optical modules will become the demand trend for connections within data centers, to match future GPU requirements for greater bandwidth and higher computing power. At present, the process of batch commercialization of 1.6T optical modules is accelerating. This trend places higher demands on optical chips: various chips including 200G PAM4 EML and CW light sources will become optical chip solutions in 1.6T optical modules. Global Optical Chip Market Size Expected to Exceed US$20 Billion in 2026 The global optical chip market size is expected to exceed US$20 billion in 2026, with data centers contributing more than 60% of the increment. For AI clusters represented by NVIDIA DGX series, the optical module ratio has increased from 1:4 to more than 1:8. 800G optical modules began large-scale volume in 2024, and 1.6T began batch delivery. Amazon, Google, Microsoft and other cloud computing companies are expected to lead the development of new AI applications, which will require major upgrades to their AI clusters, and AI clusters need to use a large number of optical connections. (III) Midstream of Optical Communication: Optical Modules + Optical Fibers and Cables Optical Communication Midstream: Optical Modules + Optical Fibers and Cables The midstream of optical communication is the "integration and transmission carrier." Its core is to connect upstream components with downstream scenarios and realize the implementation of optical signal "conversion—transmission—networking." Optical modules are the core interface for photoelectric conversion (including high-speed and telecom types); optical fibers and cables are the transmission carrier of optical signals; optical communication equipment is system-level networking equipment, mainly including core equipment such as switches. At present, the domestic computing infrastructure market supporting data and AI computing has grown from RMB 339.7 billion in 2020 to RMB 614.4 billion in 2024. In this market, computing resources rank first, with a scale of RMB 385.8 billion in 2024, accounting for about 63%; network resources rank second, with a scale of RMB 151.6 billion in 2024, accounting for about 25%. Network resources mainly include products such as switches and optical modules: switches grew from RMB 31.5 billion in 2020 to RMB 44.7 billion in 2024, and are expected to reach RMB 66.9 billion in 2029; communication resources such as optical modules are expected to reach RMB 97.8 billion in scale later. 1.Optical Modules Definition of Optical Module An optical module is like the "dedicated translator" between electrical signals and optical signals—the information in computers and mobile phones is all electrical signals, which cannot travel long distances at high speed through optical fibers. The optical module first converts electrical signals into optical signals, allowing the information to "fly" along the optical fiber to its destination; after arrival, the optical module converts the optical signals back into electrical signals, so that the equipment can read the information. Schematic Diagram of Optical Module Structure An optical module is mainly composed of optical transmit/receive components (TOSA, ROSA), a circuit board with electrical chips, a package housing, and interfaces. In terms of cost, optical devices (including optical chips) account for more than 70% and are the core of photoelectric conversion; auxiliary materials such as the housing, PCB, and control chips (electrical chips) account for nearly 30%, responsible for physical packaging and signal adaptation. Together they form the hardware foundation of the optical module. Optical Module Cost Structure High-speed optical modules must rely on high-end optical chips as the "core power." Large models such as ChatGPT are competing for computing power, AI servers need to install more GPUs, and optical modules must also be upgraded to 800G or above to be sufficient. Google’s TPU clusters rely on all-optical networks to transmit data, and demand for 800G/1.6T optical modules is growing more and more intense. Moreover, under the same computing power, TPUs require far more optical modules than GPUs, and also have higher requirements for optical transmission density. Optical Module/Optical Chip Cost Proportion In optical module costs, optical devices account for 73%, among which optical chips are key—the higher the speed of the optical module, the higher the cost proportion of optical chips, reaching 30%–70%. Now domestic optical chips are gradually gaining strength in the high-end market, and the pace of substitution is accelerating, allowing domestic manufacturers to earn more profits. Simply put, the level of optical chips determines the grade of optical modules; the higher the module speed, the more valuable the chip. 2020–2029 Global Optical Module Market Size The global optical module market has grown steadily for many years, mainly driven by applications requiring high-speed data transmission such as AI, cloud computing, and 5G—AI servers must support the operation of large models, and optical modules are their key components. From 2020 to 2024, the global optical module market size rose from US$11.2 billion to US$17.8 billion, with an annual growth rate of 12.2%, and is expected to reach US$41.5 billion in 2029, with an annual increase of 18.5%. Among them, 800G, as the mainstream high-end model of high-speed optical modules, had an annual growth rate of 188.1% from 2020 to 2024; the next-generation 1.6T optical module, driven by demand for higher bandwidth and lower power consumption, is expected to have an annual growth rate of 180% from 2024 to 2029 and will usher in explosive growth. Global Optical Module Market Size Expected to Exceed US$37 Billion in 2029 According to LightCounting’s forecast, the global optical module market will continue to expand at a compound annual growth rate (CAGR) of 22% from 2024 to 2029, and the market size is expected to exceed US$37 billion in 2029. Growth is mainly driven by strong demand for Ethernet optical transceivers from AI clusters and continuous upgrades of DWDM networks by cloud service providers. Chinese Manufacturers Occupy a Dominant Position in the Global Ethernet Optical Module Market Chinese manufacturers occupy a dominant position in the global Ethernet optical module market. In 2021, China’s optical component and module manufacturers achieved a historic breakthrough: the revenue of the top ten domestic suppliers exceeded the sales of Western competitors for the first time. From 2022 to 2023, the sales gap between domestic optical module manufacturers and foreign manufacturers continued to widen, highlighting the competitiveness of Chinese suppliers in the global market. 2025 is regarded as the first year of commercial use of 1.6T optical modules. Chinese manufacturers occupy a dominant position, with shipments in the first half of 2025 accounting for 45% of the global total, and the yield rate of high-end products exceeding 90%. On September 7, 2026, Goldman Sachs Released an In-Depth Report on the Global Optical Module Industry The industry is expanding capacity rapidly. Some analyses predict that global 1.6T optical module production capacity may exceed 30 million units in 2026. On September 7, 2026, Goldman Sachs released an in-depth report on the global optical module industry. Based on growth in AI infrastructure spending, product structure upgrading toward high-speed transmission, and rising adoption of optical interconnection, it raised its forecasts for global optical module shipments from 2026 to 2028 by 21%, 31%, and 31%, respectively, and raised its forecasts for shipments of 1.6T and above by 29%, 61%, and 50%, respectively. Goldman Sachs expects the global optical module market size to reach US$68 billion, US$131 billion, and US$148 billion from 2026 to 2028, up 33%, 81%, and 115% respectively from previous forecasts. Among them, the market for 800G and above has a CAGR of 69%, reaching US$45 billion, US$108 billion, and US$130 billion, respectively. 2.Optical Fibers and Cables Optical fiber is a slender fiber made of glass or plastic. Its core consists of a high-purity quartz core that transmits optical signals and a low-refractive-index cladding that achieves total reflection, with an outer resin coating to enhance hardness. An optical cable is a finished cable made by bundling multiple optical fibers together and combining them with protective structures such as reinforcing steel wires and sheaths. It can protect optical fibers and adapt to different scenarios. The optical fiber preform, which accounts for 70% of optical cable costs, is mostly produced by manufacturers themselves. China is the "number one producer and user" of optical fibers and cables in the world. The continuous advancement of domestic communications infrastructure has driven steady growth in optical cable line length. As of the first half of 2025, the total length of optical cables nationwide had reached 73.77 million kilometers (equivalent to nearly 1,845 times around the Earth), up 9.9% year on year. Among them, access network optical cables accounted for nearly 60%, local network relay optical cables accounted for 38.5%, and long-distance optical cables accounted for only 1.6%. Optical Cable Line Length and Its Growth Rate In response to shrinking local market demand, domestic optical cable enterprises have strengthened overseas layout under a complex geopolitical environment: from 2019 to 2022, China’s optical cable export volume increased from 255,500 tons to 408,800 tons (an increase of 60%), and export value increased by 41%, reaching a peak in 2022. 2019–2024 China Optical Fiber Preform, Optical Fiber, and Optical Cable Export Volume and Export Value In 2024, the global optical fiber and cable market share was relatively concentrated. The top 10 enterprises belonged to 5 countries including the United States, China, and Japan, together accounting for 92% of the market share: Corning ranked first with 19%. Four Chinese enterprises including YOFC and ZTT entered the top ten. Among them, YOFC (13%), ZTT (11.3%), and Hengtong Optic-Electric (11.2%) ranked second to fourth, and FiberHome Telecommunication (9.8%) ranked sixth. 2024 Global Optical Fiber and Cable Competitive Landscape: Four Chinese Enterprises Including YOFC Enter the Top Ten (IV) Downstream of Optical Communication: Optical Communication Equipment + Terminal Application Scenarios Downstream of the Industry Chain: Optical Communication Equipment + Terminal Application Scenarios Optical communication equipment is equipment that transmits information using light waves, and its core consists of three parts: signal sending, transmission, and reception. By application field, it is divided into transmission equipment and data communication equipment: transmission equipment includes transmission network and access network equipment. Common transmission equipment includes optical transceivers, fiber optic transceivers, etc.; common access network equipment includes OLT, ONU, and ODN equipment, etc.; data communication equipment mainly includes routers and switches.

Kinghelm has its own RF reliability laboratory in Dongguan Tangxia, capable of performing the following tests independently: Environmental tests: High/low temperature cycling, high/low temperature storage, 120-hour salt spray, and damp heat aging. Mechanical tests: Repeated mating life, vibration testing, mechanical shock, and cable bend/swing tests. Electrical/RF tests: Insulation resistance, dielectric withstand voltage, contact resistance; VSWR and insertion loss RF performance testing using a network analyzer. For certain stringent third-party certification requirements, we can also cooperate with external accredited laboratories.

The length of RF cables can be customized according to the customer’s specific application requirements. Standard cable lengths typically range from a few centimeters to several meters. For applications with limited installation space or short distances between modules, ultra-short RF cable assemblies with lengths of around 10 mm or more can be provided. These compact cables are suitable for applications such as internal module connections, board-to-board connections, and connections between RF modules and antennas, helping minimize cable space while meeting installation and assembly requirements. For longer RF cables, especially those measuring several meters, the cable length needs to be evaluated together with the operating frequency, cable type, physical dimensions, impedance requirements, and allowable signal loss. As cable length increases, insertion loss during RF signal transmission also increases. Therefore, for long-distance or high-frequency applications, low-loss RF cables are generally recommended to help maintain signal integrity, transmission quality, and overall system performance. RF cable lengths are not limited to standard specifications and can be cut and customized based on the customer’s equipment structure, installation distance, and application requirements. Whether you need millimeter-level ultra-short cables, conventional cables ranging from several centimeters to hundreds of centimeters, or meter-level long cables, customized solutions can be evaluated according to the specific project requirements. For cable lengths beyond the standard range, we can further evaluate the appropriate cable type and assembly solution based on the operating frequency, maximum allowable insertion loss, installation environment, bending requirements, and other application conditions, ensuring that the selected RF cable meets the electrical and mechanical requirements of the system.

Standard board-level RF connectors, such as SMA and IPEX, are generally not waterproof by themselves. They are mainly designed for applications where the connector is installed inside the equipment or is not directly exposed to water and moisture. If waterproof and dustproof performance is required, waterproof RF connectors, sealed cable connectors, or other sealing components can be selected according to the application requirements. With proper sealing structures, such as sealing rings, gaskets, and sealants, waterproof RF connectors can typically achieve IP65 to IP67 protection ratings. IP65 provides protection against dust and water jets, while IP66 offers enhanced protection against powerful water jets. IP67 can provide protection against temporary immersion in water, making it suitable for many outdoor communication devices, vehicle-mounted equipment, industrial equipment, security systems, and other applications requiring a higher level of environmental protection. For applications requiring an even higher level of protection, IP68 can also be developed and customized according to the customer's specific requirements, drawings, samples, or application conditions. The final IP68 rating will depend on the overall product structure and the applicable test conditions. It is important to note that the waterproof rating does not depend solely on the connector itself. It is also closely related to the overall structural design, sealing ring material and dimensions, connector-to-housing fit, cable exit design, assembly process, and installation method. Therefore, the connector should be designed and verified together with the equipment housing, panel, cable, and sealing structure to ensure that the required protection level can be achieved. The final waterproof rating should be confirmed based on the actual product structure and verified through the corresponding standardized testing.

SMA connectors are small coaxial connectors widely used in RF and microwave systems. They feature a compact size, high mechanical strength, and reliable connections. Their impedance, frequency range, and operating temperature are as follows: Impedance: Standard SMA connectors are 50 Ω and can match well with most RF transmission systems, test instruments, antennas, and coaxial cables. Although 75 Ω versions also exist on the market, they are mainly used in special applications such as video and broadcasting, and generally cannot be directly mated with 50 Ω SMA connectors. Otherwise, impedance mismatch, degraded VSWR, and signal reflection may occur. Frequency range: Conventional SMA connectors operate from DC to 18 GHz, which can meet the needs of most wireless communications, radar, test and measurement, and microwave component applications. Precision SMA versions using precision machining, high-quality insulating dielectrics, and strict tolerances can extend the frequency range to 26.5 GHz. Higher frequencies usually require 3.5 mm, 2.92 mm, 2.4 mm, or other connectors. The actual usable frequency is also affected by the cable assembly, PCB transition, soldering quality, and mounting method. Operating temperature: The general range is -65°C to +165°C, depending on the insulating dielectric, housing and contact materials, plating, and sealing structure. Commonly used PTFE dielectrics, stainless steel or brass housings, and gold- or nickel-plated contacts can support a wide temperature range. Different material and plating versions may vary slightly, and the upper limit of some low-cost versions or versions with plastic accessories may be lower. When used for soldering cables, the solder melting point, cable jacket, and strain relief can also limit the overall temperature performance. Therefore, when selecting a connector, the datasheet of the specific model should be used as the basis, and environmental and electrical factors such as thermal cycling, vibration, humidity, and frequency matching should also be considered comprehensively.

Song Shiqiang (left), General Manager of Kinghelm and Slkor, presents the August 2026 Sales Champion award to Zhou Yuan. Strong sales drive business growth, and Zhou Yuan was named the August 2026 sales champion of Kinghelm (http://www.kinghelm.net/) and Slkor (http://www.slkoric.com/). At Kinghelm, Zhou Yuan has set himself a ten-year goal: to become one of the company's leading sales professionals, help the company become a leader in the antenna and connector industry, and grow alongside the company. The Chinese character "Yuan"can mean "head"and, by extension, "beginning"— the starting point of something. For Zhou Yuan, that starting point is his hometown of Meishan, Sichuan Province, a place he still speaks of with deep affection: "I was born in Meishan in 1993. Su Dongpo (Su Shi, 1037–1101), one of the leading literary figures of the Northern Song dynasty and one of the Eight Great Prose Masters of the Tang and Song dynasties, has long been a source of pride for the people of Meishan. Together with his father, Su Xun, and his younger brother, Su Zhe, he is known as one of the "Three Su." Their lives, achievements and spirit have had a profound influence on me. The Three Su Shrine Museum, which includes the Three Su Memorial Hall, is a National First-Class Museum in China. I have visited the museum many times, and each visit has deepened my appreciation of the enduring appeal of Dongpo and Three Su culture across the centuries." Zhou Yuan visits the Three Su Shrine Museum in Meishan, Sichuan Province, spring 2025 Zhou Yuan of Kinghelm Sales Department Two, a native of Meishan, Sichuan Province Zhou Yuan divides his journey from his hometown to southern China into three stages. The first stage was in Guangzhou. He began working there in 2012 as a printing machinery operator, where he gained his first systematic experience in equipment operation and maintenance, on-site management, end-to-end quality control, safety compliance and teamwork. The second stage was Shenzhen. Seeking better career opportunities, he moved to Shenzhen at the end of 2012 for a better opening, and his first stop was handling customer complaints at SF Express, a Fortune Global 500 company. Four to five years in the role gave him first-hand experience of the importance—and scarcity—of high-quality customer service, eventually leading him toward a career in sales. The third stage was his transition into sales. He entered sales at the end of 2016, initially working in the automation equipment sector and selling high-precision linear guide rails and ball screws, then kept sharpening his skills and gathering experience in other industries. In February 2023 he joined Kinghelm (http://www.kinghelm.net/) as a salesperson, entering the semiconductor and electronics industry and providing customers with one-stop solutions for microwave and RF signal transmission and reception. General Manager Song Shiqiang (center) presents a team award to Kinghelm Sales Department Two Kinghelm (http://www.kinghelm.net/) provides strong support for employee development, helping accelerate Zhou Yuan's professional growth. He did not know that Song Shiqiang, the boss of Kinghelm and Slkor (http://www.slkoric.com/), was also from Sichuan. It was through General Manager Song Shiqiang that colleagues from Sichuan and Chongqing began joining the gatherings of the Sichuan-Chongqing electronics industry networking group, known as "Chuan-Yu Tongxin Hui "; the company put together the Slkor Warriors basketball team and the Kinghelm badminton team and organizes games and meet-ups regularly, and through them he has been lucky enough to meet a great many Sichuan-Chongqing entrepreneurs, fellow townspeople, peers and friends who share his interests. "Playing sports after work keeps me fit, strengthens friendships, and allows me to contribute to the company and to industry exchanges," he said. We also wish the Kinghelm brand continued success across its extensive product portfolio, including Type-C, SMA, IPEX, MCX and HDMI connectors; automotive wiring harnesses; adapter cables; pin headers and terminals; RF cables and connectors; antennas, including GPS, WiFi, Beidou, built-in, 4G and ceramic antennas; electronic components and sensors; millimeter-wave products; and a wide range of switches, jacks and other interconnect products.

August 2024: Kinghelm and Slkor basketball training, with General Manager Song Shiqiang (fourth from left) and Zhou Yuan (center) March 2025: Kinghelm and Slkor spring training, with Song Shiqiang (seventh from left) and Zhou Yuan (second from left) March 2026: Kinghelm and Slkor spring training, with Song Shiqiang (eighth from right) and Zhou Yuan (seventh from left) Basketball and badminton, Zhou Yuan says, have been part of his life since middle school. "I started playing basketball in middle school because it keeps me fit and helps me make friends who share the same interest. Even today, I play mainly for the enjoyment and the experience of taking part. I’m actually better at badminton." Friendship comes first, competition second — and Zhou Yuan is happy to share what he has learned: "In basketball, I usually play point guard, or the No. 1 position. My job is to bring the ball safely up the court and defend the opposing team’s main playmaker. I set up plays rather than finish them. So I play cleanly and fairly, both for my own safety and for everyone else’s, and simply enjoy the game." Sales champion Zhou Yuan in an interview with the Kinghelm press team Looking back on his journey from salesperson to sales champion, Zhou Yuan attributes his success to one thing: meeting customer needs and closing deals. "The approach is simple: first understand and match the customer’s needs precisely, then build trust step by step and let the deal follow naturally. But none of this works without a deep understanding of the company and its products. That knowledge takes time to build and absorb, and it is the foundation for serving customers well and closing deals." To build that foundation, he breaks the sales process for RF and high-speed connectors into three steps: finding customers, visiting customers and closing deals. He keeps the process simple and moves forward steadily, learning from each customer interaction and continuously refining his approach in the field. Step one: finding customers — focusing on high-value leads. He assesses a target company’s industry, size and key pain points, prioritizes companies that are expanding capacity, upgrading their technology or seeking domestic alternatives to imported components, and focuses on high-potential A-class customers. Step two: visiting customers — building trust and uncovering their real needs. With engineering customers, he spends more time discussing applications and solutions, connecting product capabilities with the customer’s actual pain points and providing practical value that can be put to use. With non-engineering customers, he builds rapport by discussing industry trends and the company’s experience and capabilities, allowing trust to develop naturally. Step three: closing deals — helping customers reach a decision without pressure. Known for his relaxed and easygoing personality, Zhou Yuan says he has also been influenced by Daoist philosophy and prefers to let things develop naturally. "My approach is simple: when a customer has a need, I focus on meeting it," he said. "Most of the time, I make sure the samples and debugging are handled properly, provide technical support, resolve application issues, and let the quality of the service speak for itself. When a customer moves into mass production or expands and new needs arise, they naturally come to me. Do the groundwork well, and the results will follow naturally."

Mr.Cen Jianjun, General Manager of CEN Ningbo Jinshan New Materials Co., Ltd. Jinshan means completing today's tasks today—a homophone for "golden mountain" or "silver mountain" —and it requires overcoming challenges like climbing a mountain. The development of the polyimide industry remains a long and arduous journey. In this issue of King Helm (www.kinghelm.com.cn), our reporting team visited Ningbo Jinshan New Materials Co., Ltd. (china-polyimide.com), a national key enterprise recognized as a "Little Giant" in specialized, refined, distinctive, and innovative industries, and conducted an exclusive interview with its founder, chairman, and general manager, Mr.Cen Jianjun. He vividly embodied the Tsinghua spirit of serving the nation through scientific research, having dedicated 29 years to advancing China's polyimide industry. He has mastered the core technology for producing high-performance polyimide films, developed various differentiated polyimide film products, and implemented the strategic vision of "playing a supporting role by developing unique polyimide products that domestic competitors cannot produce, thereby addressing customer pain points." Cen Jianjun emphasized that achieving high-quality development of China's economy necessitates first resolving the bottleneck in high-end materials within the industrial sector. Polyimide (PI) is one of the best organic polymer materials in terms of comprehensive performance, hailed as the "golden film" and "golden plastic." It boasts advantages such as resistance to extreme temperatures, high insulation, strength, radiation resistance, self-extinguishing flame retardancy, halogen-free environmental friendliness, excellent mechanical properties, and ease of recycling, making it a core material for strategic emerging industries including AI computing power, advanced semiconductor packaging, aerospace, gas separation, flexible displays, and new energy vehicles. The polyimide (PI) industry is a quintessential capital-and technology-intensive sector characterized by high technological barriers, substantial investment requirements, and significant added value. The global market exhibits an oligopolistic structure dominated by premium products and profits. Mr.Cen Jianjun stated: "Foreign companies have imposed significant technological constraints on polyimide development in many aspects, while China has long faced challenges of 'excess low-end production and reliance on imported high-end products.' CEN Jinshan is committed to advancing into the high-end product segment, continuously innovating and launching differentiated PI products to overcome the technological bottlenecks in high-end polyimide film materials, break foreign monopolies, and address the shortcomings within the domestic industry." I.Cen and Tsinghua University Tsinghua Garden, Image source: Mr.Zhao Ming, Chairman of Tsinghua Fei'en Steven Cen, whose English name "Steven" derives from Latin and Greek meanings of "crown" or "flower crown," graduated with a bachelor's degree from Tsinghua University in 1992. He recalled: "Born in 1969, I was admitted to Tsinghua University in 1987 from Yuyao High School in Ningbo, Zhejiang Province, enrolling in the Department of Hydraulic and Hydroelectric Engineering, majoring in Hydropower Engineering Architecture. During my five-year undergraduate program, what impressed me most was how outstanding my classmates were. I faced all challenges courageously; although some efforts ended in failure, I refused to be defeated—my inherent refusal to give up and growing resilience after setbacks are gifts that Tsinghua has bestowed upon my life. The aspiration to' integrate personal development into collective endeavors and closely link personal achievements with those of the university and the nation' has shaped the direction of my life." Since its establishment in 1911, Tsinghua University has embodied the spirit of "redressing national humiliation and dedicating itself to the motherland." The "Tsinghua Spirit" —referring to the patriotic sentiment and commitment to serving the country among its members—was deeply rooted in this ethos. After graduating from Tsinghua University in 1992, Cen Jianjun was initially assigned to a water resources and hydropower design institute. Inspired by Deng Xiaoping's Southern Tour speech, he decisively left the government sector to pursue entrepreneurship. Seizing opportunities of the era, he joined one of the most innovative real estate and foreign trade companies of the time, leveraging its wealth-creation potential and contemporary relevance. Starting from a sales position with access to extensive market information, he learned through practical experience, customer insights, and market trends. Later, he independently operated foreign trade businesses and established factories, but faced closure due to inadequate quality control. Cen Jianjun summarized this experience: "Product quality is the lifeline of an enterprise—the foundation for market competitiveness and the guarantee of sustainable development. It determines an organization's fate; without quality, there can be no growth." The academic rigor and keen insight of Tsinghua University alumni once again opened the door to entrepreneurship for Cen Jianjun. He recalled: "When the internet first emerged in 1996, many people doubted its potential. Yet I recognized the immense business opportunities it held. I began using the internet to gather information, connect with clients, and conduct trade. It was under the impetus of 'Internet+' that I delved into materials science in 1997, gradually deepening my expertise through practical trading experiences. In 1998, the call to accelerate the development of private enterprises inspired me, but the experience of factory closures made me more cautious and focused. After thorough preparation, I returned to entrepreneurship in 2001 by establishing my own factory, strictly controlling product quality from then on." For over two decades, Mr.Cen has dedicated himself to the polyimide industry, leading his team to develop high-end polyimide products competitive with international standards. He consistently embodies an innovative spirit of self-improvement, striving to overcome technical bottlenecks—a true reflection of the dedication characteristic of Tsinghua researchers. As chairman and senior engineer of Ningbo Jinshan New Materials Co., Ltd., he has served for years as vice president and secretary-general of the Ningbo Tsinghua University Alumni Association, currently holding the position of executive vice president, and is also a member of the Tsinghua Entrepreneurs Association (TEEC).

She Weixin, Founder of Huaxinjia and Jiazheng Xincheng Huaxinjia symbolizes support for the rise of Chinese chips. Jiazheng Xincheng, born from Huaxinjia, insists on authentic, original products and aims to help everyone achieve a better life through this internet platform. In this issue, Kinghelm (www.kinghelm.net) interviews She Weixin, founder of Shenzhen Huaxinjia Technology Co., Ltd. and Jiazheng Xincheng. This post-2000s entrepreneur from Chaoshan entered Huaqiangbei in 2019 and dove into the chip and sensor distribution business. With an entrepreneurial spirit of bold vision and brave action, he has done every task well and delivered every chip with excellence. Today, he has paved his own entrepreneurial path, gained inner freedom, and is committed to the cause of Chinese chip independence. Mr. Song Shiqiang emphasized that Kinghelm, Slkor (www.slkoric.com), Huaxinjia（https://hxjkj.ic.net.cn/）, and Jiazheng Xincheng are all "Chinese Chip" enterprises that seized the opportunity of domestic substitution. They are developing increasingly well and actively embracing the era of the Internet of Everything. As a first-tier authorized distributor of Slkor, Huaxinjia’s founder She Weixin is a young man full of drive, ambition, and mission. Under his leadership and pioneering efforts, the "dual-wheel drive" of the Huaxinjia and Jiazheng Xincheng brands is bound to accelerate development and create a brilliant new future. Huaxinjia is a first-tier authorized distributor of Slkor She Weixin was born in 2001. At 18, he ventured alone into Huaqiangbei; at 21, he started his business from scratch. Known in the industry as "Manager She," he has walked a path that many dare not take. When asked how he did it, he replied: "Before starting my business, I worked in the Huaqiangbei electronics market for three years. I handled deliveries, procurement, and sales, mastering every part of the workflow. ‘Think it and do it, dare to pioneer’ — this is my life principle. In 2022, I wanted to achieve something and make money. With encouragement from clients who trusted me, I started my own business with only a little over 20,000 yuan in startup capital. There is no perfect plan in life. Overthinking creates only problems; taking action brings all the answers. Huaxinjia has now been operating for five years. It wasn’t that I saw hope and then persisted — it was through persistence that I saw hope." The view from Huaxinjia’s office on the 55th floor of Seg Plaza in Huaqiangbei — truly beautiful "Shenzhen" scenery! A love for nature has always been part of She Weixin’s pursuit. Growing up in Shenzhen amid bustling traffic and towering neon lights, he enjoys keeping native stream fish. "In my Huaxinjia office, I keep two kinds of fish. By the door is a black-tail upside-down catfish, and by the window is a ‘One-Eye Taoist.’ Both are hardy native fish I collected from wild streams. They are resilient and full of vitality. Watching them swim freely every day feels like returning to nature," he said. He also loves outdoor badminton, cycling, and travel. "Doing things well, staying healthy, and living peacefully and happily — these are my requirements for myself. Realizing financial freedom early and touring the beautiful rivers and mountains of our motherland have always been my dreams." Huaxinjia’s native ecology fish — Denison barb Huaxinjia + Jiazheng Xincheng: Fueling the Rise of Chinese Chips! The tea room at Huaxinjia with its excellent window view! Shenzhen Huaxinjia Technology Co., Ltd. (Huaxinjia) was founded in 2021. Its founder and general manager is She Weixin, and its headquarters is located in Room 5505A on the 55th floor of Seg Plaza. Adhering to the business philosophy of "Do every task well and deliver every chip with excellence," Huaxinjia focuses deeply on the semiconductor industry, insists on authentic original products, and specializes in the distribution of chips, sensors, electronic components, and other hardware. Its represented brands include TI (Texas Instruments), ST (STMicroelectronics), NXP, Honeywell, GigaDevice, ROHM, Slkor, Allegro, Skyworks, ADI, Kinghelm, and many others. Founder She Weixin added, "Huaxinjia is a combination of my parents’ names and the character ‘Xin’ (chip). It carries my sense of responsibility and dedication to my family. I have always believed that doing something you love is far more romantic than just saying loving words." 2022 was his first year of entrepreneurship, coinciding with a significant reduction in chip imports and the inevitable push for domestic substitution. He emphasized, "Huaxinjia is fueling the rise of Chinese chips. We continue to accumulate experience and grow through it. Most of our customers come through referrals from long-term clients." Jiazheng Xincheng, derived from Huaxinjia, was established in 2025. Its name reflects the commitment to authentic original products and the creation of a chip mall platform to benefit others. Regarding the company’s platform-based operations, She Weixin explained: "We set up two companies because market clients and end customers require separate management. Jiazheng Xincheng focuses on the domestic terminal business. ‘Better quality and better prices are what we take seriously’ (as stated in the signature of the video account ‘Chip-Weixin’). A chip transaction is only the beginning. Huaxinjia, on the other hand, is a trader with price advantages serving market clients." Company Vision: Let everyone achieve a better life through the Huaxinjia platform. Company Values: Create value for customers. Company Goal: Become a qualified chip supplier with a complete supply system. Company Mission: Do every task well and deliver every chip with excellence. Huaxinjia’s sales of represented Slkor products are booming! When discussing core competitiveness, founder She Weixin stated clearly: "Huaxinjia’s core strength lies in its increasingly mature ‘One Core, Three Pillars’ system — integrity, channels, products, and brand. This continuously strengthens our main business and growth momentum. Huaxinjia has become a member of platforms such as IC Trading Network, Alibaba, and Huaqiang Electronics Network, while earning the trust of many customers and support from original manufacturers and agents." He mentioned that from late 2023 to 2024 was a low point in his life. A series of events brought the company to the brink of bankruptcy and left him personally in debt. Thanks to timely customer orders, support from supplier channels, and his own determination to start over, he successfully turned the company around from losses to profits. It is worth noting that the domestically produced Slkor brand products represented by Huaxinjia are selling extremely well, covering many models such as SS8050, SS8550, MMBT5551, MMBT5401, MMBT3904, SS310, 1N4148W, SM4007PL, 1N4148WS, 1N4148WL, FR107, DSK34, LL4148, AMS1117-3.3, AMS1117-5.0, M7, SS54, SS36, SS34, SS14, and more. She Weixin affirmed: "Slkor products sell very well for us." Both Huaxinjia and Jiazheng Xincheng sincerely thank the original manufacturer Slkor for its strong support, as well as General Manager Song Shiqiang for his positive energy and Sales Deputy Director Lin Yuanfang for her excellent service. He hopes that Huaxinjia and Jiazheng Xincheng, like Kinghelm and Slkor under Mr. Song Shiqiang’s leadership, will achieve steady, far-reaching, and brilliant development on the high-speed path of "dual-wheel drive." He also hopes for long-term, successful cooperation among Huaxinjia, Jiazheng Xincheng, Kinghelm, and Slkor, working together to strengthen brand synergy and achieve win-win growth. She Weixin of Huaxinjia (first from left) was invited to attend the 2025 Slkor Distributor Conference A wise youth makes a wise nation; a wealthy youth makes a wealthy nation; a strong youth makes a strong nation. Huaxinjia and Jiazheng Xincheng’s founder She Weixin is young and accomplished, deeply rooted in the chip industry. Facing national "strong chip" policies, the "Guangdong Strong Chip" initiative, and the flourishing "Chinese Chip" enterprises across the country, he praised them: "These are all good things. Technology needs development, and humanity needs progress." In the face of accelerating changes in China’s chip sector, Huaxinjia embraces new challenges, solves difficulties when they arise, and remains humble when achieving success, letting everything else follow its natural course. When asked about methods for cultivating a good mindset and positive image, She Weixin sincerely shared the following: He believes that one’s appearance reflects the heart, so it is important to remain kind and maintain a positive and upward attitude. Live your own life, do your own things, and immerse yourself in your own world — happiness in life is the ultimate goal. He also advises spending more time communicating with positive, high-energy people. For example, Mr. Song Shiqiang of Kinghelm and Slkor is straightforward, sincere, full of positive energy, and always willing to share and help others. In addition, one should learn through work and practice on real tasks. Treat yourself as a salesperson and focus on doing solid, practical work. He has a workbench at home: during the day he handles important matters at the company, and in the evenings he returns home to deal with琐碎 details. He lives by the idea of fate and connection — when you meet someone, there is affinity, and one should offer help whenever possible. He regularly makes anonymous donations to impoverished mountainous areas, proactively helps people around him who fall ill, and donates to children he encounters in mountainous regions during travels. Finally, even in difficult times, one should uphold justice and morality rather than harm others to benefit oneself. Huaxinjia’s team is very young, with an average employee age of 24. When recruiting, character comes first. Here, Kinghelm (www.kinghelm.net) and Slkor General Manager Mr. Song Shiqiang, who also developed in Huaqiangbei, sincerely wish their distributor Huaxinjia （https://hxjkj.ic.net.cn/） and Jiazheng Xincheng ever greater success, and together contribute to the companies’ future listings!

Screenshot of related information released by defrauded merchants in Huaqiangbei Song Shiqiang of Huaqiangbei said earnestly, "You can't walk in the jianghu without getting cut. If you get cut, you get cut; after you get cut, you still have to keep walking!" Fraud is common in Huaqiangbei business. Our Huaqiangbei Mini Encyclopedia column has compiled this information in the hope of purifying Huaqiangbei's business environment, enabling practitioners to operate with integrity, helping consumers avoid being cheated, making buying and selling in Huaqiangbei reassuring, and making Huaqiangbei's overall business more prosperous. The "pig-farming scam" in Huaqiangbei electronic components has existed for many years, and several cases almost every year are reported. It uses the industry's credit-term rules: "pay small amounts on time in the early stage to build trust, then concentrate large-value goods fraud and run away." It is contract fraud with illegal possession as its purpose, specifically harvesting electronic component suppliers. Its targets are IC chips, passive components, and other spot goods. Often, the fraudulent company makes multiple suppliers fall victim, with involved amounts ranging from hundreds of thousands to tens of millions of yuan. A few months ago, a company called "Yuzhou*Hui" defrauded many Huaqiangbei merchants of tens of millions of yuan, and many of them were my friends. This time, the scammers packaged themselves as an SMT factory. When Kinghelm (www.kinghelm.net) and Slkor (www.slkoric.com) first entered the industry, we were also defrauded twice, with amounts of RMB 83,000 and RMB 256,000 respectively. The lessons were painful. Photo taken at Chuangxin Cloud Electronics Market, New Trend Frontline, Huaqiangbei Core Logic of the Huaqiangbei "Pig-Farming Scam": 1.Packaging the Entity (Setting the Stage) Scammers first use fake or borrowed ID cards to register shell companies. They rent offices in office buildings around Huaqiangbei, do simple decoration, recruit purchasing salespeople, and look like a regular trading company. They claim their customers are terminal production factories and large foreign trade orders, and inquire everywhere in industry groups and spot goods circles for suppliers. Even the salespeople do not know that the boss is running a scam; the whole staff cooperates in the act. Features: There is no real purchasing demand. From the beginning, the scammers prepare for "disappearing afterward and making tracing difficult." 2.Finding Pigs and Raising Pigs (Accumulating Credit, Laying Groundwork for Months) Scammers prioritize shops or companies with hot parts and sufficient inventory, offer slightly higher than market prices, and "raise" multiple suppliers at the same time. They first place small orders with cash on delivery and transfer payment immediately upon receipt, never delaying. After getting the goods, the scammers immediately dump them below market price to cash out, actively taking small losses. The purpose is to buy trust: after continuous multiple transactions, suppliers see stable payment and growing orders, judge the customer to be a high-quality big customer, and many suppliers gradually relax risk control. Next, the scammers begin testing: they continue placing orders in batches with gradually increasing amounts, then apply for short-term credit terms (7 days, 15 days), citing factory payment cycles and financial processes, promising a small amount of credit first, and settling on time when due. Features: The scammers' active losses are the cost of buying trust. All transactions are groundwork; the goal is the final large-value goods fraud. 3. "Killing the Pig" and Running Away (Concentrated Slaughter) When the time is ripe, scammers often use the excuse that "a new project is going into production and a large order is needed, but funds are temporarily tight." They simultaneously place super-large orders with multiple suppliers and apply for extremely long credit terms. What they want are mostly common models and hot "internet-famous" chips in the market, which are easy to dump for cash. They request "deliver all goods first, agree on payment terms, and pay no deposit." Many suppliers, because of long-term timely payments before, are unwilling to lose a big customer and agree to ship. Once the goods are in hand, the scammers quickly dump chips and other components in the Huaqiangbei market at low prices to cash out. After cashing out: the office is emptied overnight, phone and WeChat are blocked, the company is deregistered or lost contact, suppliers cannot get payment, and the goods have already been sold. Features: Behind large-volume orders, the entity is falsely registered, personnel are temporarily hired, and after the case, personnel disappear and assets are transferred in advance, making evidence collection and asset recovery difficult. Delivery cart, one of the early "Four Treasures of Huaqiangbei" defined by Song Shiqiang! Derivative Variants of the "Pig-Farming Scam": 1.Batch-amplified credit-term version: Do not suddenly place a huge order; instead, slowly increase the credit limit and keep pressing goods, and run away only after accumulating a large enough amount. 2.Mixed-order scam: Mix in a small amount of real terminal demand, mixing true and false orders to further lower suppliers' vigilance. 3.Joint disguise: Forge factory workshop photos, purchase contracts, and customer project materials, and even intentionally or unintentionally invite suppliers to visit (the visited site is temporarily rented). Huaqiang Electronics World, photo by Kinghelm reporter (www.kinghelm.net) Reasons for the High Incidence of the "Pig-Farming Scam": Chips are easy to cash out + industry credit-term practices + lack of risk control among small merchants + low-cost packaging of shell companies by scammers + poor information sharing among suppliers + difficult post-event recovery. In addition, suppliers' information is not synchronized. Under the combined effect of these multiple factors, pig-farming goods fraud in Huaqiangbei repeatedly occurs. Huaqiang Electronics World Shenzhen Store 3: One-Stop Electronic Procurement and Trading Market Avoidance Guide for the "Pig-Farming Scam": No credit terms for new customers; either cash before delivery or collect a deposit (not less than 30%). For new companies, must verify the legal representative's real name, business risks, and litigation records, conduct on-site visits to verify the authenticity of operations, listen more to peer evaluations and trade references, and use bank review where conditions permit. Multiple suppliers should exchange information; pay attention in industry WeChat and QQ groups to whether the same company is simultaneously inquiring with multiple suppliers for the same materials. Be highly alert to customers who only take spot goods, only care about delivery speed, and do not care about product quality; customers who continuously buy at high prices; and customers who suddenly increase order volume and demand large credit terms. For large orders, try to collect a deposit; for popular chips and high-value ICs, prioritize cash. When accounts receivable are overdue, directly freeze the customer's new orders to avoid "shipping while they owe." Shenzhen Huaqiang Small Loan Co., Ltd. It is worth mentioning that the above points rely only on human prevention and will inevitably become lax over time. Therefore, many Huaqiangbei spot suppliers have chosen to use systems. For example, Longwei ERP's six recommended configurations turn the "pig-farming scam" into a management safeguard where "the system will not let it pass": # Control Longwei ERP's Six Recommended Configurations 1 Customer Risk Tagging Mismatch between registered capital / number of insured employees and purchase volume → Automatically flag the customer; no payment terms by default. 2 Credit Limit Order amount exceeds remaining credit limit → System freezes the order; release requires approval. 3 Payment-Term Tiers For new customers, the first 3 orders must be paid before shipment. Payment terms are unlocked progressively after on-time payments. 4 Abnormal Growth A customer's monthly order value increases by more than 3× month over month → Mandatory risk-control review. 5 Price Alerts Unit price deviates by ±20% from the market reference price, or falls below cost → Highlight in red and block the transaction. 6 Overdue Account Linkage At T+1 after payment becomes overdue → Automatically freeze new orders; at T+30 → Escalate to collections.

Many chip traders use this agreed phrase: "Delivery at the stone lions at Jiahe; cash on delivery." Uncle Song of Huaqiangbei tells everyone, "If you often wander the jianghu, how can you avoid a knife?" Fraud happens from time to time when doing business in Huaqiangbei. Our Huaqiangbei Mini Encyclopedia column has compiled this information, hoping to purify the business environment of Huaqiangbei, so that practitioners can operate with integrity and be less likely to be scammed. The Huaqiangbei electronic components "cash on delivery scam" uses the transaction promise of "in-person inspection on delivery; if unsatisfied, do not accept it" to lower buyers' vigilance. It relies on the underlying industry loophole that electronic components "cannot be distinguished as original, ground, refurbished, or pulled parts with the naked eye or in a short time," combined with process loopholes in courier COD collection and private-account settlement. Then, through information isolation between buyer and seller and non-escrow payment channels that block post-transaction rights-protection paths, it achieves profit-making or payment-interception fraud. The everyday bustle of Huaqiangbei, with endless braised pork trotter rice. The mainstream routines and derivative variants of the Huaqiangbei electronic components "cash on delivery scam" include: 1. COD collection with visually similar inferior or counterfeit goods (the most common; small purchasers and small factory buyers frequently fall into this trap) Scammers use social software and industry groups to send customers attractive real photos and original-packaging photos, quote prices significantly lower than the market price, and use scripts such as "original stock, COD supported, open-box inspection in person, reject directly if unsatisfied, no deposit required" to attract traffic. This is actually also one of the common transaction modes in Huaqiangbei. After buyers take the bait, scammers use courier COD collection. Because component "inspection" has two layers: appearance inspection, which couriers can do, and electrical parameter/function testing, which requires instruments and cannot be done in a courier scenario, scammers exploit the information gap between these two layers to substitute "appearance is fine" for "goods are qualified." Buyers generally can only quickly count and look at packaging, with no time to power up, test parameters, check silkscreen markings, or trace origin. Once they scan and pay, or transfer money to the delivery person or collection agent, it is equivalent to "accepting the goods as qualified." But after taking the goods back to the factory for SMT placement and machine installation, they find the goods do not match: refurbished or pulled parts, ground and re-marked codes, counterfeit goods, short quantities, ground and re-silkscreened parts, pulled old parts or mixed good and bad parts, aged inventory parts, domestically printed counterfeits passed off as imported genuine goods, and re-reeled refurbished parts. By then the COD funds have already been settled to the sender, the scammer, and the scammer directly disappears or refuses to acknowledge it and shifts blame, saying, "Signing for receipt means confirmation; burning out after installation is human damage and not covered by warranty." There are also cases where, due to a missing evidence chain, they falsely accuse the buyer of swapping the goods, then directly block the buyer. Couriers and platforms do not accept disputes over the electrical quality of components, and the buyer passively bears the loss. A few days ago, I saw that a female boss in Huaqiangbei bought a cut-down version of Xilinx FPGA products, with the price differing from the original by 10 times, and is still in litigation. Variant: the courier COD and on-site delivery mixed-material scam. A reel of parts looks normal on the outside, or a small amount of bad parts is mixed in. A small sample check may pass, but after large-volume SMT placement, failures occur in a concentrated fashion, even burning PCB boards, amplifying customer losses. The White Pigeon scam is similar to this scam: it artificially isolates the real buyer and the real supplier and manipulates things in the middle to defraud money. There is also a goods-fraud model: scammers impersonate buyers and trick suppliers into delivering goods to a designated location. After signing for receipt, they find an excuse to run away and resell the goods, leaving the supplier unpaid. The "Golden Mushroom Head" in Huaqiangbei is also a high-frequency meeting place for goods. 2. Swapping scam (a two-way trap; suppliers are more likely to fall for it) There are two situations. 1) Buyer-side swapping: the seller sends goods by COD; the buyer opens the box in front of the courier and quickly swaps them, preparing an empty reel or bad parts with the same appearance in advance, then says the goods do not match and requests rejection. When the courier returns the goods, the merchant finds that their goods have been swapped. The payment cannot be collected, and the genuine parts are gone. 2) Seller-side swapping: the sample is good, but the bulk goods are replaced with bad parts. After the buyer receives the goods, rights protection is difficult. Reverse version: the buyer places an order, receives the goods, and then uses "needs testing" as an excuse to stall the seller, after which they request partial refunds or return swapped goods for various reasons. 3. Deposit plus COD balance composite scam Scammers first collect a small deposit to lower the buyer's vigilance and promise that the balance will be paid by courier COD. When shipping, they directly send inferior parts, short-quantity parts, or empty reels. Even if the buyer rejects the package, the deposit is directly swallowed by the scammer. 4. Empty package or short-quantity scam (small-amount traffic bait) Scammers lure orders with extremely low prices, promise COD, and make the package weight close to that of a genuine parts reel. The buyer signs and pays, opens the package, and finds an empty reel, a scrap reel, or only a few sample parts inside, with a serious quantity mismatch, but the scammer has already disappeared.

High-incidence reasons for the Huaqiangbei "cash on delivery scam": 1.Transaction model flaws (the core): COD requires full payment on the spot, which treats payment as acceptance of the goods and puts the quality verification obligation after payment. Many small and medium-sized traders are accustomed to inquiring and ordering online via social software, delivering offline or by courier, and collecting payment via private cards, without platform escrow, corporate accounts, or rigorous contracts. Scammers artificially separate buyers from real suppliers, defrauding both sides and intercepting payment. 2.Psychological loopholes on both sides: buyers mistakenly believe COD is zero-risk and relax risk control when encountering urgent orders or low-priced spot goods. Sellers, the real suppliers, want to close deals, accept the condition of "deliver first, collect payment later," trust intermediaries' promises, and do not verify directly with the end buyer. 3.Loose market format: scammers do not operate at fixed businesses in the market; they only borrow market merchants' information and business-license photos to commit fraud, making it difficult for market managers to identify them in advance. Many backpackers and temporary middlemen are highly mobile, collection accounts can be changed at any time, and real-name information is easily impersonated or rented, making tracing difficult. 4.Ambiguous industry terminology: there is no unified standard for pulled parts, pulled old parts, and similar terms. Sellers use oral expressions to create information gaps and pass off inferior goods as good ones. 5.Complex spot-goods speculation chain: ownership is difficult to clarify, materials change hands many times, and pulled parts, refurbished parts, loose new parts, and original parts are mixed in the circulation pool of the Huaqiangbei electronics market. The boundaries themselves are blurred, leaving room for scammers to "pass off inferior goods as good ones." 6.Relatively low cost of illegality: one set of scripts, multiple social accounts, and rented bank cards or collection accounts enable low-cost crime. After success, scammers quickly cancel accounts and change identities, and funds are easily split and laundered, making arrest and loss recovery difficult. 7.High threshold for evidence and rights protection: grinding chips and changing silkscreen text are professional counterfeiting, and ordinary people can hardly retain effective evidence. Chip authenticity and quality require professional testing, which is costly. Disputes are easily classified as commercial disputes and difficult to file as fraud cases.

Huaqiangbei "cash on delivery scam" avoidance guide: The scam's COD arrangement treats "cannot power up and test on site" as an established rule, deliberately cuts off direct communication between buyer and seller, and a price far below market, scarce parts claimed to be in stock, and acceptance only of private-account or courier COD full payment are all high-risk signals. To prevent fraud, do the following: 1.For COD, try to agree on "allowing on-site inspection, supporting platform escrow, supporting corporate transfer, and agreeing that the buyer may bring simple testing tools for on-site testing," as well as "at the receiving site, only count quantity and check appearance, and pay only a small advance payment; seal and retain samples of the goods and take them back; pay the balance after power-on testing passes; if unqualified, return in full and the seller bears shipping." At the same time, agree on a clear testing period, generally 3 to 5 working days, complete power-on and function testing within the period, and keep test reports. 2.Prohibit intermediaries from isolating buyer and seller. Buyer and seller must directly verify identity and collection accounts by phone and video. Prefer fixed stalls, ask for real photos of the stall and business license, and prioritize platform escrow transactions and corporate transfers. 3.Record the entire receiving process. The buyer should video the unpacking, counting, silkscreen, appearance, and sealing and packing of samples. Individually sealed samples should be labeled and confirmed by both buyer and seller, because prevention is far more important than post-event rights protection. 4.If defective goods appear, such as ground silkscreen, changed codes, refurbished goods passed off as original, or pulled old mixed materials passed off as tested good products, the buyer should immediately send photo, text, and video evidence and first negotiate with the seller. Do not delete chat records, and do not make a second payment directly after private negotiation. If negotiation fails, the buyer should preserve evidence and complain to 12315 and the market management office. If the amount is large, the other party disappears, or there is deliberate counterfeiting and payment interception, organize a full set of evidence and report to the police.

How many entrepreneurs can one street produce? Put that question to Huaqiangbei, and the answer will stretch your imagination. What makes this district remarkable is not just the sixty-odd billionaires it has helped create, but also the companies and entrepreneurs that have gone on to transform entire industries.Kinghelm's best-selling ceramic antennas, FPC antennas and chip antennas The best-known name in tech is Ma Huateng of Tencent. He was 27 in 1998 when he and a classmate started the company in a small office at the SEG Science and Technology Park, and it was here that Tencent generated its first major revenues through QQ and later went public in Hong Kong. The story has been told countless times and remains one of Huaqiangbei's strongest calling cards. Tencent aside, Han's Laser, DJI, Kinghelm and Slkor also spent their early days taking their products from zero to one in Huaqiangbei.Where Tencent began, photographed at the Huaqiangbei Museum The computer and networking equipment sector also produced several founders who are major figures you cannot ignore. Wu Haijun of Hasee Computer could not rent a decent storefront in the early days and had to start from someone else's small counter selling computer parts and accessories, before building Hasee into a mainstream domestic PC brand. Zhao Jianjun, founder of the TP-LINK router business, also began among the counters of Huaqiangbei. Other companies that emerged from the district include Kingdee, TP-LINK, Coship and EVOC. The most inspiring story is probably Wang Li, chairwoman of Horn Audio. According to industry veterans, Wang Li began her career as a coil-winding worker on a factory production line before moving to Huaqiangbei to sell mobile phone microphones from a retail counter. Seeing that the trade worked, she set up on her own. She kept studying and improving herself as she worked, ran the company on scientific management and standardised practice, and the business grew and grew. Horn Audio is now a leading company in the industry.Song Shiqiang (right) of Kinghelm and Slkor at the appreciation banquet for JLC's listing The past five years have also seen a new generation of success stories in consumer electronics and semiconductors. Cai Huabo began trading memory products from a counter in Huaqiangbei in 1999, and later the company developed its own controllers and firmware; in 2022 Longsys, run by Cai Huabo and his sister, listed on ChiNext and became a leader among domestic memory module makers, and in 2026 it added Hong Kong H shares. Zhang Qingsen, founder of UGREEN, came to Shenzhen in 2007 as a foreign trade salesperson, then moved from contract manufacturing for other brands to a brand of his own, selling data cables into more than a hundred countries through e-commerce channels, and the company ended up on the Shenzhen Stock Exchange. Bluetrum, which makes chips for TWS earbuds, rode the wave of white-label earbuds in Huaqiangbei and listed on the STAR Market in 2022, its prospectus disclosing chip sales in the hundreds of millions. Another notable chapter in Huaqiangbei's entrepreneurial story is the rise of JLC: in 2006 Yuan Jiangtao pulled together 100,000 yuan and started from a one-metre counter in Huaqiangbei, and over two decades he, Ding Hui and Ding Huixiang developed a manufacturing model built around small batches and fast turnaround, one that took the group public in 2026 with a market capitalisation above 100 billion yuan.Kinghelm's best-selling IPEX, FAKRA, SMA, and BNA board-mount connectors These people took very different roads. Some sold components, some built brands, others developed chips, and one entrepreneur began on a factory production line. What they share is plain to see: the nerve to venture, to act, to innovate and to break past themselves. Perhaps that is the real legend of Huaqiangbei — it never promises anyone success, but it always keeps a place where an ordinary person can begin. None of these entrepreneurs got where they are without the ecosystem around them, and every one of them carries, in their work and in their bones, the Huaqiangbei spirit of risk-taking, innovation, perseverance and pragmatism — the spirit that Kinghelm (www.kinghelm.net) and Slkor, under Song Shiqiang, have distilled from the district.Kinghelm's best-selling GE113 RF adapter cables, SSMA adapter cables and more Which companies and entrepreneurs will be the next to achieve a major breakthrough?

Countdown to APEC CHINA 2026: Huaqiangbei Is Bursting with Festive Atmosphere! Huaqiangbei's Uncle Song tells everyone, "If you roam the marketplace long enough, how can you avoid getting cut?" Being cheated in business in Huaqiangbei happens from time to time. Our Huaqiangbei Mini Encyclopedia column has compiled these cases in the hope of purifying Huaqiangbei's business environment, enabling practitioners to operate with integrity and avoid being scammed. The "White Pigeon scam" in Huaqiangbei electronic components is a typical "ABC two-sided setup scam (getting something for nothing)" in the components trading field. The scammer misuses the credentials of real companies, artificially creates information isolation between buyer and seller, intercepts the transaction payment, and obtains the value of the goods at zero cost, while implicating three parties as victims. It is named after the earliest scammer, whose online name was "White Pigeon." The Huaqiangbei White Pigeon scam (original + derivative variants) has three major categories of tricks: 1.Payment interception trick (classic original, most famous) The scammer disguises as a purchaser from Company A, asks Company B for its business license and contract template, obtains the full set of materials, and forges the official seal. Then, posing as a Company B employee, the scammer finds buyer C and signs a contract using favorable commercial terms such as "supply below market price, payment after delivery and inspection, no deposit required." The receiving account on the contract is scammer A's private account. C is told that someone will be sent to deliver the goods to the door, and is warned: "The delivery person is just a runner. Do not discuss price or contract with him. If there is any issue, only contact A directly." Then A approaches real supplier D, proposing to "purchase D's goods above market price," and requires D to deliver to C's address without a deposit. D is also warned: "Do not communicate with buyer C about price, do not bypass the middleman, and payment will be made immediately after inspection." When D delivers the goods to C and C passes inspection, C transfers the payment to the scammer's account according to the contract; after receiving the money, the scammer immediately disappears. Consequences: Scammer A obtains the payment; supplier D loses the goods; buyer C loses money; Company B has its credentials misused and is drawn into disputes, damaging its goodwill. 2.Goods defrauding version (reverse White Pigeon, derivative variant one) Scammer A obtains the credentials of buyer C's company, impersonates Company C to place an order with real supplier D, and agrees to pay after the goods arrive at C's warehouse for inspection (actually a shell company/collection point controlled by the scammer), asking D to deliver there. During the process, D is not allowed to contact the real Company C directly (or key information is blocked). After the goods are delivered and signed for, scammer A directly resells them, and supplier D receives no payment. Difference from the original: the original defrauds payment, and the scammer disappears immediately after receiving the money; this variant defrauds chip goods, and the scammer sells the goods and runs away. 3.Long-term farming and rolling multiple orders (serial setup credentials version, derivative variant two) The scammer simultaneously impersonates multiple purchasers, collects the licenses and credentials of multiple companies in bulk, accumulates a pile of corporate credentials, and reserves "shell companies" to rotate shells and commit fraud. Once one order is exposed, the scammer immediately switches to the next company, continuously running multiple White Pigeon setups and committing fraud in batches on a rolling basis. Harm: The operation cycle is longer, the victims are not the same group, concealment is stronger, and investigation is more difficult. 2026 "China Year" Emblem Reasons for the high incidence of the "White Pigeon scam": The habits of spot trading in electronic components (no deposit, middleman isolation, payment to private accounts) + the low cost of license misuse + profit temptation driven by market conditions + lack of risk control among small and medium-sized merchants + difficulty in tracing funds after fraud—together these factors cause two-sided ABC scams such as the White Pigeon scam to recur repeatedly. "White Pigeon scam" Pitfall Avoidance Guide: For buyers: Strictly ensure that "contract Party A = recipient = payer"; all names on the documents must be consistent; prioritize corporate bank transfers and refuse payment to private accounts outside the contracting entity; For large orders, verify the contracting company by phone before payment to confirm that the order is genuine and valid; When the goods arrive on site, proactively confirm face-to-face with the delivery party which company it belongs to and what price it quoted. For deliverers: Do not use the contact information the other party sent you. Check business registration records yourself on Qichacha/Tianyancha, find the company landline published on the official website, and call to clearly verify the identity of the contact person and the order information; For large orders, prioritize an on-site visit, or request a video call with an employee of the contracting company and see the person's workstation and employee badge; Do not agree to "deliver the goods to a third-party address without collecting a deposit"; when delivering on site, proactively check the order, model, and price face-to-face with the receiving purchaser; inspection does not equal delivery—remember to complete the signing and handover only after receiving full payment.

According to authoritative sources, Huaqiangbei’s total annual transaction value across all electronics categories exceeds RMB 4800 billion, making it the leading electronics trading hub in China by transaction value. Its comprehensive ecosystem covers the entire electronics supply chain, including AI-powered smart hardware, traditional consumer electronics, and electronic components. Huaqiangbei: China's No.1 Electronic Street. First, the annual transaction scale of AI smart hardware was approximately 293 billion yuan, and its share jumped from 41% in 2025 to 61%, making it the fastest-growing segment in recent years and officially replacing traditional consumer electronics as Huaqiangbei’s largest pillar category. Among them, the annual transaction scales of AI smart wearables (AI glasses, smart rings, etc.), AI robots (desktop humanoid robots, industrial robotic arms, etc.), AI imaging and drones, AI learning/translation terminals, and other AI innovative hardware were 102 billion yuan, 76 billion yuan, 51 billion yuan, 37 billion yuan, and 27 billion yuan, accounting for 34.8%, 25.9%, 17.4%, 12.6%, and 9.2%, respectively. Futian Wings - Pengcheng Low-Altitude Robot Exhibition Center, photographed in Huaqiangbei. Second, the annual transaction scale of traditional consumer electronics was approximately 120 billion yuan, accounting for 25%. Among them, the annual transaction scales of mobile phone communication complete devices and accessories, computer DIY and digital complete devices, home audio-visual and small home appliances, and second-hand and refurbished digital circulation were 52 billion yuan, 31 billion yuan, 22 billion yuan, and 15 billion yuan, accounting for 43.3%, 25.8%, 18.3%, and 12.5%, respectively. Third, the annual transaction scale of electronic components was approximately 67 billion yuan, accounting for 14%. Among them, the annual transaction scales of general passive components (resistors, capacitors, MLCC, etc.), general semiconductor chips (MCUs, memory chips, etc.), AI and industrial-grade dedicated chips, and connectors, structural parts, and other components were 24.5 billion yuan, 21 billion yuan, 13.5 billion yuan, and 8 billion yuan, accounting for 36.6%, 31.3%, 20.1%, and 12.0%, respectively. In addition, the third edition of the "Huaqiangbei AI Eight Steeds" new product list was announced, featuring eight benchmark innovative products, including AI exoskeleton wearables, Santi Intelligent AI PC, Creality AI 3D printer, Hongzhili AI brain-computer interface, Zhixuetong AI dual-screen translator, Visual Universe AI glasses-free 3D, UBTECH AI desktop robot, and DingTalk AI recording card. Robotics, the low-altitude economy, smart wearables, and high-end chips have been clearly designated as the four core pillar industries of Huaqiangbei in the AI era, also referred to as the new "Four Treasures of Huaqiangbei." Before this, during the grassroots entrepreneurial stage, Huaqiangbei's one-meter counters, merchants' delivery pushcarts, shop owners' flip-flops, and roadside pork trotter rice were defined by Mr. Song Shiqiang of Kinghelm (www.kinghelm.net) and Slkor (www.slkoric.com) as the "Four Treasures of Huaqiangbei." Robotics is one of the four core pillar industries of Huaqiangbei in the AI era, photographed in Huaqiangbei. It is worth mentioning that the core business district of Huaqiangbei gathers more than 115,000 business entities, covering one-stop procurement of 1.1 million types of electronic components. The vast majority of core components can be fully sourced within one day. This also reflects Song Shiqiang’s definition that "Huaqiangbei is a reservoir on the electronic components supply chain," and it is also a central node in the electronic industry chain and ecosystem, ensuring that the cycle from concept to prototype sample for new products is compressed to within 7 days. Surrounding business entities include: offline physical counter merchants (transaction end): 22,000; office-based solution companies, R&D companies, and cross-border trade companies (without offline stalls): 63,000; logistics, customs declaration, testing, repair, and other supporting service providers: 21,000; factories outside the special economic zone and affiliated registered entities: 9,000. The vast majority of core entities among Huaqiangbei’s traditional consumer electronics merchants are offline physical counter merchants, of which more than 60% have completed AI business format transformation. The once densely packed phone case, power bank, and no-name tablet counters have largely withdrawn, all replaced by AI hardware storefronts such as AI glasses, companion robots, and smart rings; however, nearly 40% of traditional consumer electronics merchants that have not completed transformation still face operating pressure from declining customer traffic and narrowing profits, and the business district has launched targeted transformation support and matchmaking services.
