Environmental reliability test and failure analysis

With the continuous development of the electronic and electrical industry, the level of consumers is also constantly improving. People are not only satisfied with the appearance and function of products. The reliability of electronic and electrical products has become one of the characteristics of product quality. It is directly related to electronic instruments. The availability of equipment affects the effectiveness of electronic equipment.

The ATC laboratory has an international advanced level of high-frequency vibration experiment system. The laboratory also has a 60kg low-frequency shake table, a 100kg free-fall test bench, a simulated transport vibration table and other mechanical environmental experimental equipment, and a number of international and domestic famous professional environmental tests The climate environment test equipment produced by the equipment manufacturer has advanced equipment technology, stable performance, complete functions, programmable control, and automatically draws test curves.
