Analysis and Solution of Short-tail of Gold Wire Bonding

摘要

Gold wire ball bonding is usually completed by the form of gold wire ball ultrasonic bonding. Gold wire ball bonding first forms a free air ball in each bonding cycle, and then the free air ball forms a strong mechanical connection with the first pad by the ultrasonic vibration of the capillary. The second bonding point is also completed by the ultrasonic vibration, and formed into a fishtail shape by wedge bonding.
