Abstract (en)
[origin: WO2019094549A1] A printed circuit board includes a plurality of layers including conductive layers separated by dielectric layers, the conductive layers including a signal layer; and via patterns formed in the plurality of layers, each of the via patterns comprising first and second signal vias extending from a first surface of the printed circuit board to the signal layer, the signal layer including first and second signal traces connected to the first and second signal vias, respectively, the signal layer further including a ground conductor located between the signal traces and adjacent signal-carrying elements.
