0.35mm Pitch Mezzanine Header for Tight Stacking
The Hirose BM28B0.6-10DP/2-0.35V(51) is a 10-position, dual-row header from the BM28 series, designed for board-to-board mezzanine connections where the vertical space budget is tight. The defining spec here is the 0.014" (0.35mm) pitch — that's the board footprint constraint, and it dictates the matching receptacle's contact spacing one-to-one. With a mated stacking height of 0.6mm and only 0.018" (0.46mm) of the header standing above the board, this part fits into ultra-slim assemblies like foldable phones, wearable electronics, or compact camera modules where every tenth of a millimeter counts.
The real value here is the solder retention feature: small tabs on the sides of the header that anchor into the solder fillet during reflow. On a 0.35mm pitch part with no through-hole posts, those tabs take the shear load from the mating cable or board, preventing the header from lifting off its pads during handling or vibration.
