Abstract: A method of brazing components of a heat sink module is described. The method may include the steps of assembling the components to be brazed, and placing a copper-silver alloy filler at junctions between the components. The assembled components may be pre-heated in an air-tight environment to burn up most of the oxygen present, and then heated to the melting point of the copper-silver alloy filler in an air-tight environment having an amount of inert gas sufficient to displace oxygen so as to avoid oxidation of the components, making the filler melt and evenly spread over the gaps at the junctions of the components. The assembled components may then be cooled to solidify the liquid filler at the junctions, to form a finished product. Also, an assembly line system for brazing the components of a heat sink module is described.
