Silver Alloy Bonding Wires

Silver Alloy Bonding Wires

Giving Form to the Technologies of a Precious Metal Maker

Silver (Ag) alloy bonding wires have excellent electrical and thermal conductivity. They are also effective wires for optical semiconductor devices such as LEDs as they have high reflectivity in the visible spectrum. In addition, as an alternative material for gold (Au) wires, costs can be reduced by approximately 80%.
