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:
(1) Antioxidant activity;
(2) Resists sulfidation reaction;
(3) Improve the reliability and service life of materials.
