It is designed for board-to-FPC or mezzanine stacking at a 0.6mm mated stack height, with a 0.014\" (0.35mm) pitch that drives a tight board footprint. Gold-plated contacts (1.97µin) on both rows suit repeated mating cycles in compact consumer or industrial electronics where signal integrity and corrosion resistance matter. The solder retention feature adds metal hold-downs to anchor the connector during SMT reflow and resist shear force from cable strain. ## What the 0.35mm Pitch and 34 Positions Mean for Your Layout The 0.014\" (0.35mm) pitch is the tightest in the BM28 series, so the board trace routing between pads must be carefully managed — typically 0.175mm line/space or tighter. The 0.024\" (0.61mm) height above board and 0.6mm mated stack height define the z-axis budget — this connector fits into ultra-thin assemblies like smartphone or wearable stacks.","metaTitle":"Hirose BM28B0.6-34DS/2-0.35V(51) Receptacle, 34 Pos","metaDescription":"Hirose BM28 series 34-position receptacle, 0.014\" (0.35mm) pitch, gold contacts, SMT with solder retention. 0.6mm mated stack.
