Board-Stacking Interconnect for Tight Z-Height Budgets
The connector sits 0.043" (1.08mm) above the board, and when mated with the matching Fine Stack receptacle, the total stack height is 1.5mm — a dimension that drives the enclosure clearance and the choice of mating half.
Gold Plating and Solder Retention for Reliable Assembly
This matters for a board-to-board interconnect that may be disconnected during test or rework. The connector also includes solder retention features, which are small metal tabs that reflow to the PCB pads and anchor the part against shear forces from the mating cable or from thermal expansion during wave soldering.
