Aluminum and Copper Bonding Wires for Power Devices
The Standard for Power Devices
TANAKA Denshi Kogyo offers high-purity aluminum (Al) and copper (Cu) bonding wires (100 to 500µm) and ribbons (width 0.5 to 2.0mm) with excellent surface properties of automotive grade. As aluminum has excellent moisture resistance , it is often used in power device applications that drive high currents under harsh environments. We also have wires for power devices that use copper, which has even better electrical conductivity.
