HEATSINK ALIGNMENT TO PRINTED CIRCUIT BOARD

摘要

An electronic device, such as a set top box comprises an enclosure that houses a circuit board having a peripheral edge positioned in the set top box. A heat sink has orientation features on its periphery that contact and orient the circuit board. Further, the heat sink has positioning tabs at a leading edge that contact a control surface on a rear wall of the set top box enclosure and orients the heat sink within the set top box. Antenna assemblies are positioned in corners of the set top box enclosure and adjacent to one of the vertically oriented walls, wherein the antenna assemblies are positioned outside the peripheral edge of the circuit board and the periphery of the heat sink.
