Abstract

A heat sink for a printed circuit board in comprised of a thermally-conductive plate having on one surface a thermally-conductive, electrically-insulative elastomer layer which conformally engages at leasts a portion of the back surface of the printed circuit board. The ends of pins of electronic components mounted on the board and desired to be cooled embed into the elastomer layer to provide a conductive path for transfer of heat from the electronic components to the elastomer layer and then to the thermally-conductive plate.
