Board-to-Board Mezzanine Connector for Tight Stack Heights
At this density, the 50-position count packs a lot of signal or low-current power lines into a small footprint, typical for LCD interconnect, camera modules, or main-to-sub PCB links in consumer gear. Gold plating at 10.0µin on the contacts gives this receptacle a solid cycle life for field-serviceable assemblies — not the hundreds of cycles a heavy-duty gold flash would, but enough for the few mate-unmate events a mezzanine joint sees in its service life. The surface-mount tails reflow onto the board pads; no through-hole solder fillets to inspect.
Stacking Height and Board Spacing
The 2.5mm mated stacking height is the single dimension that decides whether this connector fits your board gap. The receptacle itself stands 2.00mm above the board, so the matching SlimStack header must bring the total to 2.5mm when mated. If your enclosure or mezzanine standoffs call for a different gap, this is the number to check against your mechanical drawing before committing the BOM line.
