Gold stud bumping
WebThe gold stud bumping process is similar to the gold ball bonding process, with the only difference being that after the bonding process the gold wire is cut off at the neck by … WebStud bumping using a traditional wire bonding process followed by the severing of the wire material from the ball bond has been widely applied in flip chip packages. Traditionally, Au stud bumps were employed because of the physical properties of gold, but the mediocre reliability of Au with Al pads and the cost of gold make this material unfavorable for …

In fact, gold ball bumping is an evolution of … WebAug 1, 2005 · The gold stud bumping process is originally derived from the modified wire bonding process (Harman, 1997). The unit operations of processing a gold stud bump with double bumping modes include the forming of a free air ball (FAB), the first bumping mode, and the second bumping mode, as illustrated in Fig. 2.
Gold stud bumping forms Au bumps using a process very similar to Au ball wire bonding. Like wire bonding it forms an Au ball (stud). However, the wire is terminated after the first bond so there is only a bump on the die. Au stud bumping requires no Under Bump Metalization (UBM) or special wafer preparation, unlike the requirements for solder ...
