Gold contact finish is standard across the series, which suits repeated mating cycles without corrosion concerns. This low profile is typical for tight enclosures where every tenth of a millimetre counts. The 0.40mm pitch drives the board footprint: trace escape between pads at this density needs careful routing, especially if inner-layer vias are involved. The solder retention features on the header body anchor it during reflow, reducing the chance of misalignment from paste slump or board handling.","metaTitle":"Hirose BM20B(0.8)-24DP-0.4V(53) Header, 24 Pos, 0.40mm Pitch","metaDescription":"Hirose BM20B(0.8)-24DP-0.4V(53) header, 24 positions, 0.016\" (0.40mm) pitch, 0.8mm stacking height.
