Copper and Copper Alloy Bonding Wires
The best product to reduce costs.
TANAKA offers high-purity copper (Cu) ultra-fine wires (down to 15um) of oxygen-free copper grade as well as palladium (Pd) coated copper wire (PCC) added with oxidation resistance through precious metal coating. Costs can be reduced by approximately 90% compared to expensive gold (Au) wires.
