Patent ID: 7902465

Claim:
A multi-layer printed circuit board, comprising: a plurality of electrically conductive layers with dielectric material disposed between the electrically conductive layers, the plurality of electrically conductive layers including a group of power planes and a group of ground planes; a first plated through-hole that extends through the multi-layer printed circuit board, the first plated through-hole including an electrically conductive lining that forms a barrel for receiving a first lead of an electronic component; and a second plated through-hole that extends through the multi-layer printed circuit board, the second plated through-hole including an electrically conductive lining that forms a barrel for receiving a second lead of the electronic component; wherein a first subset of the group of ground planes is electrically and mechanically connected to the electrically conductive lining of the first plated through-hole, and wherein a second subset of the group of ground planes is free from electrical and mechanical connections to the electrically conductive lining of the first plated through-hole; and wherein the group of power planes is electrically and mechanically connected to the electrically conductive lining of the second plated through-hole.
