Lead Frame Strip/KFC Certifications
Lead Frame Strip/KFC Advantages
-
Lead frame material has good strength, electrical conductivity, thermal conductivity and other comprehensive performance, can meet the design requirements of lead frame industry.
-
The lead frame material has good performance of softening at high temperature and resisting thermal stress relaxation, which can improve the reliability of devices under working conditions.
-
Lead frame material surface quality is excellent, with good plating and weldability, for the subsequent processing technology to provide convenience.
