SMT termination and board fit
The 90863-110 is the 20-circuit member of Amphenol ICC (FCI)'s Rib-Cage™ III board-to-board header line. It terminates by surface-mount solder reflow — the pick-and-place feature supports automated assembly without secondary handling. The shrouded 4-wall housing guides the mating receptacle and the push-pull fastening type keeps insertion force low during board stacking.
Mated stack height and row spacing
The mated stack height is 6.42 mm. Dual rows on a 0.050" (1.27 mm) row-to-row pitch match the mating pitch, so the board footprint is symmetric and the stack height is consistent across the 20 positions.
