Surface-Mount Termination and Board Retention
The BM07B-SRSS-TB(LF)(SN): Termination is surface-mount solder — the header sits flat on the PCB pads and reflows in a standard SMT oven. The solder retention feature adds mechanical hold to the SMT joints, helping the connector stay anchored during cable strain or vibration after the receptacle is mated. Mated stacking height is 4.9 mm, which defines the z-height budget between the PCB and the mating wire assembly — useful when the connector sits in a tight enclosure or under a cover.
