Abstract
Printed circuit includes a planar substrate having opposite sides and a thickness extending therebetween. The sides extend parallel to a lateral plane. The printed circuit also includes a plurality of conductive vias extending through the planar substrate in a direction that is perpendicular to the lateral plane. The conductive vias include ground vias and signal vias. The signal vias form a plurality of quad groups in which each quad group includes a two-by-two array of the signal vias. Optionally, the printed circuit also includes signal traces that electrically couple to the signal vias. The signal traces may form a plurality of quad lines in which each quad line includes four of the signal traces. The four signal traces of each quad line may extend parallel to one another and be in a two-by-two formation.
