Patent ID: 7132746

Claim:
An electronic assembly comprising: a housing member comprising a heat-conductive member; a substrate supported by the housing member, the substrate having conductors on a surface thereof; a circuit device mounted to the substrate with solder connections on a first surface of the device that are registered with the conductors on the substrate, the device having a second surface oppositely disposed from the first surface; and a solder joint consisting essentially of an indium preform into which one or more alloying constituents have diffused to increase the melting temperature of the solder joint above that of the indium preform, the solder joint bonding the second surface of the device to the heat-conductive member; and an overmold compound that encapsulates the substrate, the device, and the solder joint on the housing member, the overmold compound having a cure temperature approximately equal to the melting temperature of indium but less than the melting temperature of the solder joint so as to enable curing of the overmold compound without adversely affecting the bond formed by the solder joint between the device and the heat-conductive member; wherein a thermally-conductive lubricant means is not present between the second surface of the device and the heat-conductive member.
