Fine pitch bonding
WebThe wire bond pull test and shear test are widely used to evaluate and control the quality of ball bonds—fine pitch and otherwise. The shear test is the only method that adequately evaluates the strength of the weld. The pull test cannot test the weld because the welded cross section is normally significantly larger and stronger than that of the wire. The … WebThe advancement in bonding technology and the market demand for faster, smaller and better product, again poses new challenges for the wire bonding process. The transition from fine-pitch (FP) to ultra fine-pitch (UFP) volume production, and the emergence of stacked die, multi-tier and low-K bonding has increased the level of difficulties in ...
