Claim of US Patent No. 10,958,001

1. A printed circuit board comprising an edge, the printed circuit board comprising:a connector footprint comprising a plurality of signal vias adjacent the edge, wherein the plurality of vias are disposed in a plurality of columns extending in a first direction perpendicular to the edge from a first end adjacent the edge to a second end, each of the plurality of columns comprising a plurality of pairs of the plurality of signal vias;
wherein:
each of the plurality of columns comprises:
at least one portion in which the pairs of signal vias have a conductor-to-conductor spacing in the first direction of a first distance;
a gap, free of signal vias, at a location between the edge and the second end, the gap spanning a distance in the first direction greater than the first distance;
the gaps of the plurality of columns align to form a routing channel extending in a second direction parallel to the edge;
the printed circuit board further comprises at least one pair of signal traces routed in the routing channel, the at least one pair of signal traces being connected to a pair of vias in a column of the plurality of columns; and
the gap is between the edge and the first end of the column.
