Patent ID: 8531841

Claim:
A method of dissipating heat from a dc-dc power converter, the method comprising the steps of: (a) placing a compressible electrically insulating underfill thermal interface material in contact with the button of the power converter; and (b) placing the compressible electrically insulating underfill thermal interfaces material contacting the bottom of the power converter in contact with a motherboard; wherein the compressible electrically insulating underfill thermal interface material fills space between the bottom of the power converter and the surface of the motherboard and thereby provides a heat conductive path that transfers heat from the power converter to the motherboard printed wiring; the compressible electrically insulating underfill thermal interface material is in the form of a compliant compressible thermal pad; and double sided adhesive tape is attached to components on the power converter to provide a non-intrusive method of attaching the power converter to the motherboard while providing compression for the thermal pad.
