Classification: CPC H | IPC H

Claim 15:
16. A circuit board comprising:
a substrate comprising a first surface and a second surface substantially parallel to the first surface;
an integrated circuit residing on the first surface of the substrate and joined electrically to the first surface of the substrate;
a contiguous metal body, a contact interface surface of the contiguous metal body contacting the integrated circuit at a first pressure via a thermal interface material along the contact interface surface;
pins, comprising a first pin oriented along a first direction, disposed inside pin receiving openings through the second surface of the substrate, the pins being integral to the contiguous metal body;
wherein the first pressure is a predetermined pressure selected to enhance heat transfer characteristics of the thermal interface material;
wherein the extent of an incursion of the contiguous metal body in the first direction is determined based on the first pressure; and
wherein the pins are rigidly affixed into the pin receiving openings to maintain the contiguous metal body in contact with the integrated circuit via the thermal interface material at the first pressure.
