0.40mm Pitch Mezzanine Plug for Tight Stack Heights
The TE Connectivity 4-2363962-0 is a 40-position, 2-row board-to-board plug with outer shroud contacts, designed for a 0.8mm mated stacking height.
At 0.8mm mated stack height, this plug pairs with a matching receptacle of the same series to create a 0.8mm board-to-board gap. The 0.40mm pitch demands a tight PCB layout.
Solder Retention in Reflow Assembly
The solder retention feature means the connector body includes metal tabs that reflow-solder to pads on the board, not just the signal contacts. This keeps the plug from lifting during the second reflow pass or from shear force when the mating receptacle is inserted or removed. For a 0.8mm stack height part, those tabs matter — the narrow profile leaves little room for a mechanical lock, so the solder joint takes the mechanical load.
