Abstract:
A heat dissipating assembly including a layered stack of materials with a highly thermally conductive path for cooling a circuit, the stack including a structurally isolated material having a high coefficient of thermal expansion connected between materials having low coefficients of thermal expansion.

Claim (Index 20):
An assembly for dissipating heat in an electronic circuit, the assembly comprising:\n a heat spreader having a high thermal conductivity and high material strength for connecting to the circuit; a substrate formed of a printed wiring assembly and being connected to the heat spreader on a first side of the substrate, the substrate having a ground plane and a low thermal conductivity, the heat spreader extending over a portion of the substrate and the ground plane, at least a portion of the substrate extending above the heat spreader; a heat slug having a high thermal conductivity and low material strength and being connected to the heat spreader on a first side of the heat slug and adjacent to the substrate, the heat slug being formed of a material selected from the group consisting of a Copper-tungsten alloy, Kovar, Alloy 42, and Aluminum-silicon alloy, the heat slug and the substrate being preformed so that stresses induced when the layered stack is at a minimum temperature and stresses induced when the layered stack is at a maximum temperature are of equal magnitude, so that maximum induced stress is minimized; and a backplate having a high thermal conductivity and high material strength and being connected to the substrate on a second side of the substrate opposite its first side and connected to the heat slug on a second side of the heat slug opposite its first side, the heat spreader, substrate, and backplate forming a layered stack of materials with a highly thermally conductive path for cooling the circuit, the heat spreader having a CTE matching a CTE of the circuit, the substrate having a CTE matching a CTE of the backplate, and the heat slug having a CTE that does not match the CTE of the circuit.
