Kovar Single Clad Copper

Kovar Single Clad Copper Bond Pads

COINING’s Kovar Single Clad Copper Bond Pads are used in high-reliability applications. Within the clad are two different pieces, and the substrate in the middle. Kovar is the substrate with a thin copper clad layer. The copper layer (the bottom layer) is used to solder to a circuit board. The Kovar layer is used to attach a bond wire, typically stainless-steel wire or gold wire. Our Kovar Single Clad Copper Bond Pads are the intermediary piece to attach to both wire and a circuit board.
