Abstract: In one embodiment, a clip pin of a secondary printed circuit board removably coupled to a primary printed circuit board and a backplate in an information handling system includes: an open end configured to receive a guide pin of the backplate within a clip pin hole of the primary printed circuit board, the guide pin configured to removably couple to the clip pin via the open end; a bulbous portion disposed proximate to the open end, the guide pin causing the bulbous portion to apply an outward force on an inner wall of the clip pin hole; and a plurality of signal pins disposed within the bulbous portion, the outward force causing the plurality of signal pins to communicably couple to the inner wall to transmit a signal from the secondary printed circuit board to the primary printed circuit board.

Abstract: In one embodiment, a grounding structure for a printed circuit board (PCB) of an information handling system includes: a first ground via electrically coupled to a ground layer of the PCB; a second ground via electrically coupled to the ground layer of the PCB; and a conductive strip electrically coupling the first ground via to the second ground via, the conductive strip providing a vertical ground reference for a signal transferred from a first surface of the PCB to a second surface of the PCB through a signal via disposed on the PCB.
