The successful manned launch and recovery of Shenzhou 9 attracted global attention. Of course, the female aerospace hero Liu Yang received the most attention in the incident, but there are many, many unsung heroes behind the scenes who actually support my country's aerospace industry. One of the difficulties in the development of the aerospace industry is the quality of the components in the spacecraft under unconventional conditions such as very harsh temperatures, space rays and huge gravitational acceleration, that is, whether the reliability of electronic products is guaranteed. As we all know, in the past when testing equipment was insufficient, components for some military and even aerospace products were mainly selected through manual screening.
The disadvantages of manual screening are obvious. On the one hand, the product cost is high, and on the other hand, the reliability is not high enough. With the development of China's domestic components, many of these companies have integrated military and civilian products. Therefore, it is necessary for domestic component companies to have a more comprehensive knowledge of reliability testing and failure analysis. Xi'an Semipower Laboratory, China's first national-level power device laboratory, recently held the first series of semiconductor power device testing and reliability technology training in Xi'an, making a great contribution to cultivating talents for the industry. The following is an exclusive interview conducted by this publication with Luo Yi, general manager of Xi'an Semipower Laboratory.
