Abstract

One embodiment of the present invention sets forth a heat spreader module for dissipating thermal heat generated by electronic components. The assembly comprises a printed circuit board (PCB), electronic components disposed on the PCB, a thermal interface material (TIM) thermally coupled to the electronic components, and a heat spreader plate thermally coupled to the TIM. The heat spreader plate includes an embossed pattern. Consequently, surface area available for heat conduction between the heat spreader plate and surrounding medium may be increased relative to the prior art designs.
