Abstract
An assembly comprising a heat generating electronic device and a heat sink is provided with an intermediate gradient region between them. This intermediate region comprises a material having a coefficient of thermal expansion substantially matching the coefficient of thermal expansion of the heat generating electronic device, and a thermal conductivity greater than the thermal conductivity of the electronic device but less than the thermal conductivity of the heat sink. Provision of this intermediate layer substantially reduces stress on the electronic device caused by thermal cycling.
