ABSTRACT:
The heat sink is mounted on a back plane of an auxiliary circuit board and the auxiliary circuit board is mounted on a main circuit board. In one embodiment, the heat sink is planer and extends between parallel auxiliary and main circuit boards. A finned heat dissipating member is at one side of the planar portion. Mounting pins in channels mount the heat sink to the main circuit board. The second embodiment is u-shaped and stands on edge to mount the auxiliary circuit board perpendicular to the main circuit boards. Mounting pins in channels of the second embodiment likewise mount the heat sink to the main circuit board.
