After the Sino-US trade war, the localization process of manufacturing has accelerated. Solder materials, as one of the main packaging materials for electronic products such as chips, are also among the domestically produced products.
Recently, we received news that after more than half a year of comparative testing and demonstration, Zhongshi solder paste performed excellently, stood out from many domestic manufacturers, and successfully passed the verification process. It can be used to replace the international brand solder paste used by customers, meeting customers' needs for domestic substitution.

Zhongshi has been engaged in independent research and development and production of solder paste for more than ten years and has obtained multiple patents for solder paste products.
The solder paste "Zhongshi ZSRH01" used in this demonstration test is a conventional product that Zhongshi Company has been serving customers for many years.
The following is part of the test report:
