<p>A printed circuit board includes a dielectric layer having a first surface and an opposing second surface and a circuit layer laminated to the first surface of the dielectric layer. Cut-out windows provide openings through the dielectric and circuit layers. A thermally conductive layer is laminated to the second surface of the dielectric layer. The thermally conductive layer includes at least one sinkpad that passes through the cut-out windows. The sinkpad is an embossed, hollow feature of the thermally conductive layer. A surface of the sinkpad may be substantially coplanar with a surface of the circuit layer and be prepared for compatibility with a solder reflow process. A heat generating electronic component may be electrically coupled to the circuit layer and thermally coupled to the sinkpad of the thermally conductive layer to form an electronic assembly.</p> |
