The 0.016\" (0.40mm) pitch drives the PCB footprint — tight enough for dense routing but requires a matching BM20 series header on the opposite board. Gold contact finish handles the mating cycles typical of internal mezzanine connections in portable electronics and compact modules. ## SMT with solder retention — holds position through reflow Surface mount termination with solder retention features means the connector stays put during reflow without secondary clips. Two rows of contacts at 0.40mm pitch give 10 total positions — confirm your circuit count matches before committing the BOM line.","metaTitle":"Hirose BM20B(0.8)-10DS-0.4V(53) 10-Pos 0.4mm Receptacle","metaDescription":"Hirose BM20 series 10-position receptacle, 0.40mm pitch, 0.80mm mated height, gold contacts, SMT with solder retention.
