ABSTRACT:
Electrically insulating but thermally conductive "heat shunt" components are attached to PC boards along with regular electronic components to improve heat dissipation. The heat shunts are typically a small bar of thermally conductive ceramic with spaced-apart metal mounting pads on the ends for soldering to the PC board. Their shape is similar to standard electronic components for placement by automatic machinery and they extend, for example, from a transistor collector contact pad on the PC board to an adjacent ground lead having holes plated through to the metal back plane of the PC board in contact with the heat sink.
