  • Patent number: 11533805
    Abstract: A clamp configured to be coupled to a printed circuit board to cool and compress one or more electrical connections subject to repeated power and thermal cycling. A first conductive column of the clamp is configured to compress a first electrical connection between a first power device lead and a first printed circuit board trace of the printed circuit board, and draw thermal energy away from the first power device lead. The first conductive column extends from a load spreading plate. The load spreading plate is an insulator that electrically isolates a fastener extending therefrom from the first conductive column. The fastener is configured to cooperate with the circuit board to connect the clamp to the circuit board, compress the load spreading plate against the first conductive column to compress the first electrical connection, and connect the clamp to ground.
    Type: Grant
