It drives the trace width and via keep-out on the PCB. Surface-mount termination keeps the bottom side of the board clear for additional components, but the fine pitch demands a solder paste stencil with good aperture alignment to avoid bridging between adjacent pads. ## Mating and Stack Height — Confirming the Pair The outer shroud contacts are the key alignment feature — they guide the receptacle into position and take the shear load during assembly, so the signal pins are not stressed. Confirm that your receptacle order code specifies the same 3 mm stack height to ensure the boards sit at the correct separation.","metaTitle":"Hirose DF12NC(3.0)-20DP-0.5V(51) Header, 20 Pos","metaDescription":"Hirose DF12 series header, 20 positions, 0.50mm pitch, 3mm stack height, gold-plated contacts.
