Abstract

The effect of electrical flame off (EFO) discharge parameters on the heat affected zone (HAZ) and bondability of gold wire was studied in this paper. The wire was fired and then bonded in a ball bonding procedure, in which the effect of EFO supplying current and firing time was analyzed. The results show that the diameter of free air ball (FAB) increases as the EFO time or current increases on the basis of a same current or time. With the increase of EFO current on the basis of a comparable FAB size, both the length and the grain size of HAZ decrease. The wire exhibits increasing tensile breaking load and elongation in the HAZ, and wire pulling force after bonding with the increase of current. The FAB under higher current presents better deformability and smaller bonded ball height. However, decreasing of ball shear force indicates the decrease of bondability with the increase of current.
