Electrical connector assembly

摘要

An electrical connector assembly in which conductor pads on a board are used as contact is described. The conductor pads (34) are alternately disposed on both sides of a board (10). The conductor pad (34a) transmits a positive differential signal, and the conductor pad (34b) transmits a negative differential signal; these conductor pads are disposed on the same side (10a) of the board (10). The ground pad (34c) is disposed on the opposite side (10b) of the board (10) so that this ground pad (34c) is positioned at an intermediate point between the conductor pads (34a) and (34b), thus forming one set of pads. In regard to the conductor pads (34d), (34e) and (34f) of another adjacent set, the pad (34d) which transmits a positive differential signal is disposed on the side of the pad (34b) of the previous set, which transmits the same negative differential signal. The ground pad (34f) of this set is disposed on the opposite side of the board (10) from the pads (34d) and (34e). The pad of a third set (not shown) which is adjacent to the pad (34e) that transmits a positive differential signal is a pad that transmits the same positive differential signal. As a result, signal crosstalk can be prevented.
