ABSTRACT:
Mounted on a circuit board in close proximity to nearby circuit components, a novel heat sink is configured to provide unobstructed tool access to one or more heat producing devices attached thereto. The heat sink includes a massive body member fastened to the circuit board, a support member upstanding from the body member and a radiator member formed integrally with both the support and body members for releasing heat to the environment. One or more mounting surfaces form part of the body member and are provided for mechanically attaching the heat producing devices to the heat sink with good thermal contact. Each mounting surface is inclined with respect to the circuit board such that any device attached to a mounting surface is accessible through an open space between the radiator member and the nearest component on the circuit board.
