Board-to-Board Stacking at 0.50mm Pitch
The Hirose DF12NC(3.0)-60DP-0.5V(51) is a 60-position header from the DF12 series, designed for parallel board-to-board stacking. The 0.020" (0.50mm) pitch packs 60 circuits into a dual-row layout, with outer shroud contacts that serve as both a ground plane and a mechanical shield between the stacked PCBs. The surface mount termination keeps the assembly reflow-compatible, though the fine pitch demands careful solder paste registration and a well-controlled reflow profile to avoid bridging between adjacent pads.
