An electrical connector assembly includes a circuit board having vias extending at least partially through the circuit hoard along parallel via axes. The circuit board includes electrical conductors exposed within corresponding vias that extend between a top and a bottom. The electrical connector assembly also includes an electrical connector mounted on the circuit board that includes a housing having a mounting face configured to be mounted along the circuit board, and a plurality of variable depth signal terminals held by the housing. The signal terminals each include mounting contacts extending outward from the mounting face of the housing that are received in respective vias of the circuit board. The mounting contacts extend different depths into respective vias of the circuit board to engage the corresponding electrical conductors. The mounting contacts have a mounting end arranged at substantially the same depth within the via as the bottom of the electrical conductor.

A contact module is provided for an electrical connector. The contact module includes a body having a mating edge portion and a mounting edge portion. A lead frame is held by the body. The lead frame includes a differential pair of terminals extending between the mating edge portion and the mounting edge portion. The differential pair includes a positive terminal and a negative terminal having positive and negative mating contacts, respectively, and positive and negative mounting contacts, respectively. The positive and negative mating contacts extend from the mating edge portion in a first orientation. The positive and negative mounting contacts extend from the mounting edge portion in a second orientation. The first orientation at the mating edge portion is inverted relative to the second orientation at the mounting edge portion.

A circuit board includes a substrate having an upper surface and a lower surface. The circuit board has signal vias extending at least partially through the substrate along signal via axes being configured to receive signal terminals and ground vias extending at least partially through the substrate along ground via axes being configured to receive ground terminals. The ground vias are arranged in a predetermined pattern around the signal vias to create a ground ring surrounding the corresponding signal via, wherein the ground vias are at least partially filled with a conductive material to create a ground column. Each ground column extends from a column top to a column bottom. A first subset of the ground columns extending to a first depth and a second subset of the ground columns extending to a second depth greater than the first depth.
