Changsha Sublimation Microelectronics Material Co., Ltd.

Kovar/Copper/Kovar(KCK) Composite Material

Our company has successfully developed kovar/copper/kovar composite strips based on the process of CPC（Cu/MoCu/Cu）and CMC（Cu/Mo/Cu）, with adjustable three-layer thickness ratio. Subsequently, etching or stamping processes are used to prepare frame leads. This material has significantly improved thermal conductivity and conductivity compared to pure kovar leads, and is widely used in the military electronics field.
