Board-to-Board Receptacle for Dense PCB Stacking
The 1MM-R-D25-VS-00-H-TBP: This 50-position receptacle from the AMPMODU 1MM series mates with a matching 1.00mm-pitch pin header in a board-to-board stack. The 2-row layout with 0.039" (1.00mm) row spacing keeps the board footprint compact — useful when routing traces between the rows on a dense PCB.
Termination is solder-only, surface-mount — the contacts are reflow-soldered to the PCB pads. The part is packaged in a box and includes pick-and-place features, so it feeds through a standard SMT placement machine without manual handling. The contact finish on the solder post is tin, 150.0µin (3.81µm) thick — this wets well with standard SAC305 solder paste and meets the wetting requirements for a RoHS3-compliant assembly line.
The base product number is 1MM-R-D, which covers the AMPMODU 1MM receptacle family — confirm the position count and plating variant when ordering.
