Abstract

A printed circuit board includes a substrate having a plurality of stacked circuit board layers. The substrate has a top surface and a bottom surface. The printed circuit board includes a signal contact on the substrate. The signal contact has a signal via and a signal trace extending from the signal via. The signal via extends between the top surface and the bottom surface along a via axis. The printed circuit board includes an anti-pad around the signal via extending through the substrate along the via axis. The anti-pad extends between the top surface and the bottom surface. The anti-pad has a first width at the top surface and the lower anti-pad has a second width at the bottom surface different than the first width.
