Patent ID: 8319335

Claim:
A power semiconductor module configured to be mounted on a heatsink, said power semiconductor module comprising: a power semiconductor chip arranged on a substrate, the power semiconductor chip comprising a bottom side facing the substrate, a top side facing away from the substrate, and an electrical contact face arranged on the top side; a bond wire bonded by at least a first bond site and a second bond site to the electrical contact face and comprising between the first bond site and the second bond site a first bond wire portion made up by the whole portion of the bond wire between the first bond site and the second bond site, the bond wire being spaced away from the electrical contact face in this portion; and a contact pressure element shaped to exert a contact pressure force on the electrical contact face in mounting the power semiconductor module on the heatsink, the contact pressure force resulting in the power semiconductor chip and the substrate being pressed against the heatsink, the contact pressure force being created responsive to the contact pressure element being urged against just a sub-portion and not against the whole of the first bond wire portion.
