In the A-share, Changchuan Technology (300604) has mastered the relevant core technologies of integrated circuit test equipment, and is one of the few domestic enterprises that can independently develop and produce integrated circuit test equipment. In the process of accelerating localization, the performance has increased, and the new products have gradually increased, and are in a leading position
Chip packaging test includes packaging and testing two links, is the semiconductor industry chain and integrated circuit industry chain downstream. Packaging is an essential link in the integrated circuit industry chain. The specific process is to protect the chip from the damage caused by physical, chemical and other environmental factors, enhance the heat dissipation performance of the chip, realize electrical connection, and ensure the normal operation of the circuit; The test is mainly to test the function and performance of the chip products, etc., and screen out the products that do not meet the requirements of function and performance
