The present disclosure relates to a printed circuit board assembly, which includes: a first printed circuit board, printed with a first transmission trace; a second printed circuit board, printed with a second transmission trace; a substrate, in which, the provides a through aperture for a radio frequency connector; and a radio frequency connector, which includes an inner contact portion, an housing and an insulating part provided between the inner contact portion and housing, where the radio frequency connector is configured to be received in and pass through the through aperture, such that a first end of the inner contact portion of the radio frequency connector is electrically connected to the first transmission trace and a second end thereof is electrically connected to the second transmission trace, so that a first end of the housing of the radio frequency connector is electrically connected to a ground layer of the first printed circuit board and a second end thereof is electrically connected to the ground layer of the second printed circuit board. Thus, the printed circuit board assembly is capable of improving aspects such as shielding effects, PIN performance and/or degree of integration compared with prior art.

A backplane connector includes a wafer and a mounting block. The wafer includes a number of conductive terminals, an insulating frame, a first metal shield and a second metal shield. The conductive terminal includes a contact portion, a tail portion and a connection portion. The conductive terminals include differential signal terminals, a first ground terminal and a second ground terminal. The first metal shield includes a first protruding piece. The second metal shield includes a second protruding piece. The mounting block includes a slot for passing through the tail portions of the differential signal terminals. The first protruding piece and the second protruding piece are at least partially inserted into the slot. This arrangement can provide better shielding adjacent to the tail portions of the differential signal terminals, reduce crosstalk, and improve the quality of signal transmission.
