According to TISCO (Shanxi Taigang), its independently developed SUS630 precipitation-hardening stainless steel cold-rolled plates are now being supplied steadily to domestic Printed Circuit Board (PCB) manufacturers. Throughout the recent holiday period, the company's R&D and production teams maintained strict quality control to ensure the material meets the rigorous standards required for 5G communications, automotive electronics, and medical devices. As a core material for the hot lamination process in PCB manufacturing, SUS630 was long dependent on foreign imports; however, TISCO has now become the only stable domestic supplier, successfully breaking the technical blockade.
