Abstract:
An apparatus comprising:a printed circuit board (PCB) having a top surface and a bottom surface; at least one electronic component, having a backside surface, mounted on the bottom surface of the PCB; a bottom heat dissipating device, having a bottom coupling portion, attached to the bottom surface of the PCB, a top surface thereof thermally coupled to the backside surface of the electronic component; and a top heat dissipating device, having a top coupling portion, attached to the top surface of the PCB, the top coupling portion contacting the bottom coupling portion, the bottom and top coupling portions jointly forming a thermally conductive coupling member being thermally coupled to the bottom and top heat dissipating devices at least one of the heat dissipating devices having recessed areas of different depths to thermally couple with electronic components of different heights.
