ASMPT Copper Bonding Wire is engineered to match ASMPT wire bonder platforms perfectly, delivering robust micro-interconnection for semiconductor backend packaging. It creates conductive links between chip pads and leadframes or substrates for signal and power transmission.
Compared with gold wire, copper features superior electrical and thermal conductivity, along with slower intermetallic layer growth at bonding interfaces. It forms uniform free-air balls under EFO spark with protective gas, supporting fine-pitch packaging and stable loop control during high-speed bonding cycles.
It is widely selected for power management ICs, discrete devices and consumer semiconductor packages. Using this matching copper bonding wire helps reduce material expenditure while maintaining bonding strength, lowering lift-off and ball defect rates for mass production.
