Switching devices play a vital role in electronics and electrical engineering by controlling circuit connectivity, adjusting current or signal levels, and enabling logical functions. Below, we provide a detailed overview of common switching devices, their characteristics, distinctions, and applications.
In electronic devices and electrical systems, connectors act as bridges for stable transmission of signals and power. The quality of these "bridges" largely depends on material selection. From metals to plastics, conductors to insulators, the distinct properties of different materials directly influence key performance metrics such as electrical conductivity, mechanical strength, and environmental adaptability. This article provides an in-depth analysis of the relationship between connector materials and performance, along with scientific guidelines for material selection.
In electronic devices and electrical systems, connectors act as "nerve hubs," responsible for critical signal and power transmission. Connector failures can lead to performance degradation or even system collapse, resulting in significant losses. Reliability testing of connectors is essential to ensure stable operation in complex environments and over extended periods. This article systematically outlines the full process of connector reliability testing across multiple dimensions—test items, standards, and methodologies—and provides practical optimization strategies.

Over 30 Years of "Craftsmanship Spirit"—An Interview with Zhao Ming, Chairman of Qingda Fien For a long time, China's information industry faced a "chip shortage and soul deficit." "Chips" refer to hardware like integrated circuits, while "soul" refers to industrial software, operating systems, and industrial product databases. Qingda Fien has made significant progress in addressing this "soul deficit." From pioneering the concept of a "Digitalization and Interconnected Quality Management System Platform" to its current work on the research and development of digital quality platform industrial software systems, Qingda Fien has created many classic cases and set industry benchmarks, serving high-end manufacturing in quality control. Chairman Zhao Ming believes that a strong manufacturing industry and quality-driven nation are the path forward. Thanks to continuous efforts from all sectors in China, the "chip shortage and soul deficit" have been alleviated, and Qingda Fien's vision of becoming a "world-leading provider of quality systems and standards" is now clearer than ever. He firmly believes that with China focusing more on high-quality development, Qingda Fien's future will undoubtedly be bright! Zhao Ming: The Tsinghua Spirit The interview with Mr. Zhao Ming by Kinghelm Mr. Zhao Ming, born in 1966 in Jiangjin, Chongqing, shared that his hometown is also the birthplace of Marshal Nie Rongzhen. "Jiangjin District is the first area where the Yangtze River enters Chongqing, neighboring Luzhou, Sichuan," he said. For rural children, the opportunity to change their destiny comes through education. Zhao Ming went from his rural roots to attend Jiangjin High School, one of the two most prestigious schools in Sichuan, and then to Tsinghua University. His journey at Tsinghua was marked by eight years of continuous undergraduate and master's studies. He recounted, "In July 1984, I took the college entrance exam and was admitted to the Department of Engineering Physics at Tsinghua University. By my junior year, I transferred to the isotope separation specialty, and upon graduation, I was granted an exemption to pursue a master's degree at Tsinghua’s Nuclear Energy Technology Design Institute." When asked about his secret to academic success, Zhao Ming shared, "Having an interest in learning, previewing lessons in advance, and paying attention in class." Regarding his reflections on the "Tsinghua Spirit," he summarized: firstly, "Tsinghua Purple," the symbol of Tsinghua students’ identity and the continuation of alumni friendship. Secondly, "No sports, no Tsinghua," as Tsinghua’s motto emphasizes health. Finally, "Red and Professional," referring to the university's balance of political ideology and specialized education.
