Abstract

A method includes preparing a bonding surface of a heat dissipating member, applying flux to the bonding surface of the heat dissipating member, and removing excess flux from the bonding surface so that minimal flux is provided. The method also includes preparing a die surface of an electronic device package, applying flux to the die surface, and removing excess flux from the die surface so that minimal flux is provided. The method further includes positioning a 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 layer of the bonding surface is in contact with the preform solder component, and reflowing the solder component using a reflow oven. A heat spreader is also described for use in the process.
