Abstract
A multi-layer printed circuit board (PCB) has a plated through hole for receiving a pin of a component. The plated through hole passes through all layers of the PCB and includes a first conductive portion on a first surface of the PCB and a second conductive portion on a second surface of the PCB. At least one layer of the PCB includes a planar conductive material disposed over a planar insulating material. The conductive material surrounds the plated through hole and is separated therefrom by a gap.
