HEAT SINK AND THERMAL INTERFACE HAVING SHIELDING TO ATTENUATE ELECTROMAGNETIC INTERFERENCE

摘要

Heat sink and electrically non-conducting thermal interface having shielding to attenuate electromagnetic interference. The interface comprises a generally planar substrate having first and second outwardly facing surfaces. The substrate is formed from a material, preferably a polymer, that is both thermally conductive and has a high dielectric strength. Formed upon the outwardly facing surfaces are layers of a thermally conductive compound for facilitating heat transfer. The invention further comprises an improved heat sink comprising a baseplate coupled with a folded-fin assembly, the latter being compressively bonded thereto via a pressure clip and pressure spreader assembly. The base plate is attachable to a heat-dissipating component, and may optionally include a ground contact connection for use with components that are not already grounded.
