摘要
A heat transfer assembly may be used to provide a thermal conduit from a module mounted on a circuit board through the circuit board, allowing a thermal path away from the module. The heat transfer assembly generally includes a thermally conductive base with at least one raised thermal pedestal accessible through at least one heat transfer aperture in the circuit board and in thermal contact with the module. In an embodiment, the heat transfer assembly is used in a remote PHY device (RPD) in an optical node, for example, in a CATV/HFC network. The RPD includes an enclosure having a base with at least one raised thermal pedestal in thermal contact with an optical module (e.g., an optical transmitter or transceiver) on a circuit board through at least one heat transfer aperture in the circuit board.
