Abstract:
A method includes electrically connecting an IC chip module to a motherboard and thermally contacting a heat sink to the IC chip module. The IC chip module includes a carrier comprising a top surface and a bottom surface configured to be electrically connected to the motherboard. The IC chip module includes a stiffening frame attached to the carrier top surface. The stiffening frame includes a base portion that has a central opening and a plurality of opposing sidewalls. The IC chip module further includes a semiconductor chip electrically connected to the carrier top surface and concentrically arranged within the central opening. The IC chip module further includes a first directional heat spreader thermally contacting the semiconductor chip. The first directional heat spreader includes a directionally thermally conductive material arranged to efficiently transfer heat from the semiconductor chip in a first opposing bivector direction towards first opposing sidewalls.
