Improving the power cycling performance of the emitter contact of IGBT modules: Implementation and evaluation of stitch bond layouts
The emitter (front metallization) of IGBTs is contacted by wire bonding. In this study, the influence of the wirebond layout on the power cycling performance of IGBT modules is investigated. Stitch bonding is implemented to modify the wirebond layout of the emitter contact. The different layouts are subjected to power cycling tests. For a better understanding of the experimental results, electr...

متن کاملCopper Wire Bond Failure Mechanisms
Wire bonding a die to a package has traditionally been performed using either aluminum or gold wire. Gold wire provides the ability to use a ball and stitch process. This technique provides more control over loop height and bond placement. The drawback has been the increasing cost of the gold wire. Lower cost Al wire has been used for wedgewedge bonds but these are not as versatile for complex ...
