In terms of structure, wires act as a bridge between the bonding pad of the chip (first bond) and the pad of the carrier (second bond). While lead frames were used as carrier substrates in the early days, PCBs are more ...
Webtwo sites. The process of connecting metal bond pads to substrate leads can be accomplished by ball bonding. Prior to bonding, the substrate and chip are pre-heated on the wire bonder heater stage to a temperature of typically 170°C for an epoxy substrate and 220°C for a metal lead-frame substrate, which aids the welding process. The ball bonding WebLight WELD Unbeatable Benefits. FAST: Up to 4X faster than TIG. VERSATILE: Wide range of materials – up to 1/4 in. (6.35 mm) EASY: Optimized presets reduce learning curve.
