Abstract
An electronic device includes a printed circuit board. The printed circuit board includes a plurality of different signaling planes and a plurality of different reference planes. A single ended via interconnects the plurality of different signaling planes. A return via interconnects the plurality of different reference planes. The electronic device includes a shared void that includes the single ended via and the return via.
Claims17
An electronic device, comprising:
- a printed circuit board comprising a plurality of different signaling planes and a plurality of different reference planes;
- a single ended via to interconnect the plurality of different signaling planes;
- a return via to interconnect the plurality of different reference planes;
- and
- a shared void that surrounds the single ended via and the return via,
- wherein a distance between a center of the single ended via and a center of the return via comprises less than a radius of the single ended via plus a radius of the return via plus a spacing between a signaling plane of the different signaling planes and a reference plane of the different reference planes.

A printed circuit board, comprising:
- a single ended via to interconnect at least two different signaling planes;
- a return via to interconnect at least two different reference planes;
- and
- a shared void that surrounds the single ended via and the return via,
- wherein a distance between a center of the single ended via and a center of the return via comprises less than a radius of the single ended via plus a radius of the return via plus a spacing between a signaling plane of the at least two different signaling planes and a reference plane of the at least two different reference planes.
2 more elements
An apparatus, comprising:
- a printed circuit board (PCB);
- an interface coupled to the PCB to connect to an interface on a computing device;
- and
- a plurality of electronic devices coupled to the PCB, wherein each one of the electronic devices comprises a plurality of shared voids, wherein each one of the plurality of shared voids surrounds a single pair of a single ended via and a return via,
- wherein the single ended via interconnects a plurality of different signaling planes of the PCB,
- the return via interconnects a plurality of different reference planes of the PCB, and
- a distance between a center of the single ended via and a center of the return via comprises less than a radius of the single ended via plus a radius of the return via plus a spacing between a signaling plane of the plurality of different signaling planes and a reference plane of the plurality of different reference planes.
