Claim:
Apparatus comprising: a frame; an electronic device mounted to the frame; a heat sink plate having a plurality of pins extending from a first surface thereof, the pins arranged in intersecting transverse and longitudinal rows defining transverse and longitudinal valleys there between; and a retaining clip having at least one leg portion thereof to couple to the frame and having a central portion thereof to engage the first surface of the plate to force a second surface of the plate into thermal contact with a surface of the electronic device, the clip central portion having at least one geometric feature, the central portion positioned to lie in at least a portion of a longitudinal valley with the geometric feature extending into at least one transverse valley for a distance exceeding a distance between adjacent pins in the transverse valley to limit longitudinal and transverse lateral movement of the heat sink relative to the surface of the device; and at least one of the pins has retaining member projecting from it into the transverse or longitudinal row to limit vertical movement of the clip central portion in the transverse or longitudinal valley.
