Claim 0:
1. A printed circuit board comprising:
a plurality of layers including conductive layers separated by dielectric layers; and
via patterns formed in one or more of the plurality of layers, each of the via patterns comprising:
first and second signal vias connecting to respective signal traces on one or more of the plurality of layers;
ground vias extending through at least some layers of the plurality of layers; and
at least one shadow via extending through at least some layers of the plurality of layers, wherein the at least one shadow via is plated or filled with a conductive material and wherein the at least one shadow via is located on a first line that passes through one of the first and second signal vias, the first line being perpendicular to a second line that passes through the first and second signal vias.
