Abstract
The demand for high density integrated deveice strongly requires the establishment of ultra-fine wire bonding technology. But the mechanism of the gold ball formation is not sufficiently cleared in the wire bonding process. In this rearch, numercal modeling of gold wire melting and pendant drop formation at the wire tip are carried out.
