Abstract:
1. A circuit assembly comprising: a substrate having oppositely-disposed first and second substrate surfaces and conductors on the first surface; at least one surface mount package comprising a package body having a first package surface and a second package surface, an integrated circuit device embedded in the package body and having input/output pads on a first surface thereof within the package, an oppositely-disposed second surface within the package and leads contacting the input/output pads within the package body and extending outside of the package body to electrically connect the input/output pads to the conductors on the first surface of the substrate, said package body being mounted upon the first substrate surface such that the first package surface is adjacent the first substrate surface; a metal heat sink adjacent the package and not separated from the package by the substrate; and a metal heat-conducting member contained within the package body adjacent the second surface of the circuit device, said heat-conducting member having a first surface bonded to the circuit device and a second surface coextensive with the second package surface and in thermal contact to the heat sink, whereby heat transfer from the circuit device to the heat sink is through the heat-conducting member.
