Numerical Analysis of the Ball Forming Process in Copper Ball Bonding

Abstract

In this paper, the process of forming copper wire balls in copper ball bonding has been studied by numerical analysis. By calculating the temperature field, speed field and displacement field for ultra‐fine copper wire under a miniarc, a regular pattern of copper wire ball formation has been observed. The calculation results for the displacement field has also been tested and verified.
