Patent number: 8733620Abstract: A solder is deposited on a heat sink. The solder is first reflowed at a first temperature that is below about 120° C. The solder is second heat aged at a temperature that causes the first reflowed solder to have an increased second reflow temperature. The heat aging process results in less compressive stress in a die that uses the solder as a thermal interface material. The solder can have a composition that reflows and adheres to the die and the heat sink without the use of organic fluxes.Type: GrantFiled: December 8, 2005Date of Patent: May 27, 2014Assignee: Intel CorporationInventors: Mukul Renavikar, Susheel G.
