POWER MODULE FOR MULTI-CHIP PRINTED CIRCUIT BOARDS
First Claim
1. A power module assembly, comprising:
- a heat distribution plate having at least first and second fields of receptacles integrally formed therein and populated with first and second fields of thermally-conductive pins, respectively, the pins capable of moving independently in a direction orthogonal to the plate responsive to forces applied to them; and
a power module printed circuit board mounted to the heat distribution plate and having first and second clearance holes formed therein;
wherein the first and second fields of pins protrude through the first and second clearance holes.

Abstract
A power module assembly for multi-chip printed circuit boards: A heat distribution plate has first and second fields of receptacles integrally formed therein. The receptacles are populated with first and second fields of thermally-conductive pins. A power module printed circuit board is mounted to the heat distribution plate and has first and second clearance holes formed therein. The first and second fields of pins protrude through the first and second clearance holes. A multi-chip printed circuit board may be mounted underneath the power module such that the thermally-conductive pins contact a surface of first and second supplied chips. The supplied chips are physically close to the power module, and thermal management for the supplied chips is provided by virtue of contact between the supplied chips and the thermally-conductive pins. Space on the multi-chip printed circuit board is conserved.
