Q-P AC 3 Thermally Conductive Pad Easy to Handle, Greaseless Thermal Interface The new Bergquist Q-Pad 3 eliminates problems associated with thermal grease such as contamination of electronic assemblies and reflow solder baths. Q-Pad 3 may be installed prior to soldering and cleaning, without worry. Q-Pad 3 thermally conductive pad consists of graphite imbedded in a polymer matrix that is elastomeric on one side, and a pressure sensitive adhesive on the opposite side. When exposed to modest heat and pressure, the elastomer conforms to surface textures thereby creating an air free interface between heat generating components and heat sinks. Fiberglass reinforcement enables Q-Pad 3 to withstand processing stresses without losing physical integrity.
