Original Abstract

This paper deals with Free air ball (FAB) formation and its optimization. It is part of the thermocompression of the thermosonic wire bonding process. This paper consists of a theoretical introduction to the topic and specific technological steps that is crucial for correct FAB formation. Technological parameters that can have an impact on the FAB formation process were analyzed. These are for example power of the electric discharge, length of the wire tail or protective atmosphere in the case of corrosive materials of the wire. The impact of these parameters on the quality of the reliability of the FAB and the wire-bonded joint were evaluated. At the end of this paper is a recommendation for the optimization of the wire bonding process for the small amount of the semiconductor chips.
