A cooling fin assembly for mounting on a semiconductor package that includes a plurality of pins adapted to be affixed to a surface on the package, and a cooling fin means having a thin walled cellular configuration with the cells defining elongated openings in side-by-side relation that extend through the fin means, the pins being seated in the cells of the fin means.

Heat sink for electronic package

A semiconductor device package having a substrate, one or more semiconductor devices mounted on the top surface of the substrate, a heat sink having a surface in opposed spaced parallel relation to the top surface of the substrate, and at least one deformable heat transfer member positioned between a device mounted on the top surface of the substrate, and the surface of the heat sink. The heat transfer member is comprised of a porous block of material, and a heat conductive non-volatile liquid retained within the block of material by a surface tension. The heat transfer member being operative to transfer heat from the device to the heat sink.
