Board-Stacking Fit for Tight Z-Height Budgets
The Molex 5035481222 is a 12-position receptacle from the SlimStack 503548 series, built as a 0.40 mm pitch, dual-row, surface-mount connector with gold-plated center strip contacts. It sits 0.68 mm above the board and mates to a 0.7 mm stack height — essentially the connector is the gap. This is a signal-only interconnect for mezzanine or parallel board stacking where the clearance between PCBs is under a millimeter.
Mating Half and Board Layout
The dual-row layout means the PCB footprint is a 2×6 grid of 0.40 mm-pitch pads — the tight pitch forces a fine-line PCB with trace widths and spaces below 0.20 mm to route signals out of the BGA-like footprint. Pick-and-place vacuum pickup is on the top surface, so the reel feed orientation must match the nozzle.
