Problems solved by technology

At present, the reliability testing process of circuit board products is very complicated, and the process methods are also of different styles, but there is no unified standard. The test is carried out by technicians according to their own experience, level, professional knowledge, etc. Due to different methods, the results will also vary. There is a big difference, which leads to the inability to make accurate tests and judgments on the reliability of the product in many cases, thus affecting the final performance of the product. Therefore, the research on the reliability test of the product is of great significance
