Abstract:
A method of heat sinking a surface mount device (SMD) component. In an example method through holes are formed in a printed circuit board (PCB), a first copper layer is electroless plated in the holes, a second copper layer is standard plated in the holes and surrounding surfaces of the PCB, a third copper layer is masked and pulse plated in the holes, the holes are filled with non-conductive material and then is sanded flush with the second copper layer. A fourth copper layer electroless plated on the PCB over the area of the holes, a fifth copper layer (or pad) plated on the PCB over the area of the holes, and a surface mount device is attached to the fifth copper layer.
