Patent ID: 7649146

Claim:
A circuit board for use with a connector carrying differential signals, comprising: a substrate, the substrate including a plurality of openings formed therein, the openings including plated portions so as to make electrical contact with conductive terminal tail portions inserted therein, the openings being divided into first and second groups of openings, the first group of openings receiving differential signal terminal tails therein when a connector is mounted to said circuit board and the second group of openings receiving ground terminal tails therein when a connector is mounted to said circuit board; each first opening having a pair of second openings associated therewith, the first opening and said associated second opening pair being arranged at apexes of an imaginary triangle, two of said first openings being spaced apart from each other and aligned with each other such that said two first openings are contained within a perimeter defined by imaginary lines intersecting said two pairs of associated second openings.
