Claim:
1. A thermal connector comprising; a heat sink having a recess; a heat spreader that fits into the recess of the heat sink; a spring, comprising a body portion that is connected flush with the heat spreader and a plurality of legs angled away from the heat spreader and towards the heat sink so that the plurality of legs contact the heat sink when the heat spreader is fit into the recess of the heat sink; a flexible membrane attached to the heat sink and to the heat spreader, so that the membrane seals off the recess; and a phase change material that fills the void defined by the heat sink, flexible membrane, and heat spreader, wherein the phase change material holds the spring compressed to its smallest height so that when the thermal connector is heated and the phase change material is melted, the heat spreader is pushed by the spring away from the heat sink and into contact with a heat generating component positioned adjacent to the heat sink; wherein the flexible membrane allows the phase change material to expand in response to the movement of the heat spreader away from the heat sink.
