Bonding Wire

Metal Wires for Semiconductor IC and LED Packaging.
Bonding wire is a metal wire connecting electrodes in semiconductor IC or LED chips with terminals on lead frames. It is an indispensable material for transmitting signals in chips. 
  • Main products include silver alloy bonding wire series and coated silver bonding wire series.
  • Characteristics of silver alloy wire:
    (1) May apply in N2 or N2+H2 gas environment;
    (2) Wire with low hardness to avoid damage on aluminum pad;
    (3) Workability and reliability are comparable to gold wire.
  • Characteristics of silver coated wire:
    Antioxidant activity;
    (2) Resists sulfidation reaction;
    (3) Improve the reliability and service life of materials.
