TANAKA Kikinzoku Kogyo K.K., which operates the TANAKA Precious Metals manufacturing business, has announced that its subsidiary TANAKA Denshi Kogyo K.K., which produces various types of bonding wires, will start taking orders for gold (Au) bonding wire manufactured using only RE Series 100% recycled precious metal materials. This is in addition to existing products, using raw materials such as gold directly produced from mines.
A gold compound for plating has already been launched by TANAKA Kikinzoku Kogyo, the first product to use the RE Series of raw materials. For its second product, the RE Series is being expanded to gold bonding wires, manufactured by TANAKA Denshi Kogyo.
Boasting the world’s highest market share*, TANAKA Denshi Kogyo’s gold bonding wires support the global semiconductor industry. A stable worldwide supply of the RE Series is possible as it is being produced at four locations; Japan, Singapore, Malaysia, and China, and has obtained third-party verification.
TANAKA Precious Metals hopes to contribute to the establishment of a Sound Material-Cycle Society, with increased demand for sustainable materials and products, by supplying the RE Series. In future, TANAKA Precious Metals will further expand its business of recycling precious metals, which are natural resources with limited reserves, to the global market with the goal of achieving a stable supply.
