Abstract:
1. An electrical connector assembly comprising: a printed circuit board defining at least an aperture with at least a conductive trace disposed therein; and an electrical connector seating into the aperture and having at least one contact electrically interconnecting with the conductive trace; wherein the electrical connector comprises an insulative substrate receiving the contacts, and the insulative substrate is made by a similar material of the printed circuit board; wherein the electrical connector further comprises a bottom substrate located under the insulative substrate, and the bottom substrate is made by the similar material of the printed circuit board; wherein the insulative substrate defines a plurality of passageways and the bottom substrate defines corresponding vias to cooperatively receive the contacts, which are electrically connected with the vias; wherein the bottom substrate is bigger than the insulative substrate to form an edge portion; wherein the edge portion has a plurality of pads located on a top surface thereof and a plurality corresponding conductors located on a bottom surface thereof; wherein some of the vias connect with the soldering pads, another vias connect with the pads of the edge portion by traces located on the top surface of the bottom substrate, the rest vias connect with the conductors by traces located inside the bottom substrate; wherein the printed circuit board includes a plurality of insulative boards, and the aperture of the printed circuit board is defined on an upper layer or upper layers of the insulative boards and has a shape corresponding to the electrical connector, the aperture has a big upper section and small lower section.
