Abstract
A circuit board is provided which includes a plurality of signal pairs of connectors. The signal pairs of connectors are disposed in a triangular grouping of three signal pairs of connectors such that a first connector of each signal pair is located at a vertex of the triangular grouping. A second connector of each signal pair is located at a side of the triangular grouping adjacent to the vertex of the first connector. The signal pairs may be differential pairs.
Claims23
An apparatus comprising:
- a circuit board;
- and
- a plurality of signal pairs of connectors arranged on the circuit board, the signal pairs of connectors being disposed in a triangular grouping of three signal pairs of connectors such that a first connector of each signal pair is located at a vertex of the triangular grouping and a second connector of each signal pair is located at a side of the triangular grouping adjacent to the vertex of the first connector.
An apparatus comprising:
- a circuit board;
- and
- a hexagonal array of grounding elements and signal pairs of connectors disposed on the circuit board;
- wherein a grounding element is positioned within six triangular groupings, each of the six triangular groupings comprising three signal pairs of connectors arranged on the circuit board, the three signal pairs of connectors being disposed such that a first connector of each of the three signal pairs is located at a vertex of the triangular grouping and a second connector of each of the three signal pair is located at a side of the triangular grouping adjacent to the vertex of the first connector;
- and
- wherein two signal pairs of connectors of each of the six triangular groupings is common to a first and second of the six triangular groupings, and wherein each connector of the two signal pairs is positioned at a vertex of the first triangular grouping and positioned at a side of the second triangular grouping.

A method comprising:
- forming a first signal pair of connectors in a substrate;
- forming a second signal pair of connectors in the substrate at a first angle to the second signal pair;
- and
- forming a third signal pair at a second angle to the first signal pair and a third angle to the second signal pair so as to create a triangular grouping of the first second and third signal pairs such that a first connector of each signal pair is located at a vertex of the triangular grouping and a second connector of each signal pair is located at a side of the triangular grouping.
