Abstract: A heat sink is disclosed comprising a metallic pin extending between a proximal end and a distal end. A lower pin stud is positioned adjacent to the proximal end. An upper pin stud is positioned adjacent to the distal end. A base flange is interposed between the lower pin stud and the upper pin stud and defines a lower base surface and an upper base surface. The lower pin stud engages a source aperture and the lower base surface engages a source surface. A composite pitch fiber encapsulates the upper pin stud and the upper base surface. The metallic pin and the composite pitch fiber transfer the thermal energy from the lower pin stud and the lower base surface, through the upper pin stud and through the composite pitch fiber for dissipating the thermal energy from the source.
