Abstract (en)
[origin: WO2016188762A1] The invention relates to an electronic device (10) comprising a printed circuit board (12) supporting at least one component including at lest one power component (14) and/or at least one power conductor (18), said printed circuit board comprising an alternating series of insulating (22) and conductive (24) layers, and sinks (30, 30') provided with an electrically and thermally conductive inner coating (32) that extend through the thickness of the board, as well as comprising a device (34) for cooling the board. According to the invention, the interior of the sinks is also filled with a thermally conductive material (44) in order to provide a thermal bridge between the component and the cooling device (34).
