Abstract:
1. A method of assembling an electronic device, comprising: mounting a heat producing component to a substrate; positioning a layer of thermal interface material on to the heat producing component such that the thermal interface material is disposed on the substrate; aligning a heat sink including the at least one mounting pin over the thermal interface material such that the thermal interface material is sandwiched between the heat producing component and the heat sink, and further the at least one mounting pin is disposed though a corresponding hole in the substrate for soldering the at least one mounting pin to the substrate; reducing the viscosity of the thermal interface material by preheating the thermal interface material in a wave soldering preheater to cause the thermal interface material to wet the component to thermally couple the heat sink to the heat producing component; and attaching the sink in a fixed position on the heat producing component and the substrate by soldering the at least one mounting pin onto the substrate while the thermal interface material is still hot.
