Patent ID: 8066532

Claim:
An electrical connector assembly, comprising: an insulative housing with a plurality of terminal passages; a plurality of contacts received in the corresponding terminal passages, each contact including a contact portion, a retaining portion and a tail portion, tail portions of the contacts arranged into two rows, tail portions of all pairs of differential signal contacts located on a same row, the contact portions of the contacts aligned on a line; and a PCB electrically connected with the contacts, and having a terminal soldering area and a wire soldering area, the terminal soldering area defining a plurality of first conductive pads on a top surface and a bottom surface of the PCB, the first conductive pads electrically connected with corresponding contacts, and the wire soldering area defining a plurality of second conductive pads on the top surface and the bottom surface of the PCB, the second conductive pads electrically connected with corresponding wires, and the first conductive pads electrically connected with the second conductive pads, the number of the first conductive pads located on the top surface different from that of the second conductive pads on the top surface, wherein the first conductive pads are defined on a narrower segment of the PCB, and the second conductive pads are defined on a wider segment of the PCB, the space between the two neighboring first conductive pads on the top surface of the PCB is different from the space between the two neighboring second conductive pads on the top surface of the PCB, the tail portions of the contacts including two types, one type of tail portion is flat, and the other type is curved, the curved tail portions have larger soldering areas than the flat ones.
