Abstract
An apparatus for transferring heat from a heat spreader is provided. The apparatus includes a heat dissipating member and a heat spreading member adjacent the heat dissipating member, the heat spreading member configured to spread heat laterally across the heat dissipating member, the heat spreading member defining a heat conduction plane. The apparatus also includes a base adjacent to the heat spreading member, wherein the heat spreading member is between the base and the heat dissipating member, and at least one thermal via within the heat conduction plane, the thermal via thermally coupled to the heat spreading member, the at least one thermal via thermally coupled to the heat dissipating member and the base through surface-to-surface contact.
