Abstract:
1. A method comprising: preparing at least two bonding surfaces on one or more of a lower surface of a heat dissipating member, a die surface, or a lower or an upper surface of a preform solder component; preparing a mating surface on one or more of the lower surface of the heat dissipating member, the die surface, or the lower or the upper surface of the preform solder component; applying flux to the bonding surfaces; removing excess flux from the bonding surfaces so that minimal flux is provided; positioning the preform solder component on the die surface; positioning the heat dissipating member over the die surface and the preform solder component such that the flux layers on the bonding surfaces are positioned between both the preform solder component and the die surface and the preform solder component and the heat dissipating member; and then first reflowing the preform solder component to both the heat dissipating member and the die surface using a reflow oven.
