Popis: We report on bond pad damage for a smart power device using 50.8 µm (2 mil) diameter Pd-coated Cu wire. We show that the damage can be relatively subtle; the wire bonds on damaged structures have high pull and shear strength, but cracks in the underlying regions lead to metal extrusions that cause electrical shorts.
