Copper and Copper Alloy Bonding Wires

Copper and Copper Alloy Bonding Wires

The best product to reduce costs.

Copper and Copper Alloy Bonding Wires reduce costs approximately 90% compared to that of gold wires. In addition, these bonding wires feature excellent electrical characteristics including electrical conductivity and fusing current, making possible use in various devices including discrete semiconductors, QFP, and BGA. We also offer copper alloy wire and copper wire with a precious metal coating to enhance reliability.
