60-Position Mezzanine Receptacle at 0.80 mm Pitch — the Board-Stacking Gap Decider
The 0.031" (0.80mm) pitch and dual-row layout give you 60 contacts in a compact footprint — the kind of density needed for a wide data bus or a dense signal interconnect between two PCBs.
SMT Termination and the Board Guide — What the Assembly Line Sees
This is a surface-mount receptacle, so it goes through a reflow oven — no through-hole wave solder. The board guide is a molded alignment feature that helps the pick-and-place machine seat the part accurately before reflow.
Gold Plating at 8.00 µin — Adequate for Controlled Mating Cycles
It is not the heavy 30-50 µ" gold you'd spec for a field-service connector that sees hundreds of insertions in a dusty factory. For a mezzanine board that gets mated once at build and maybe a few times during rework, 8.00 µ" gold is adequate. The gold is on the mating surface; the solder tails see the reflow profile directly.
