Board-Stacking Fit for Tight Z-Height Designs
The Hirose BM28B0.6-10DS/2-0.35V(51) is a 10-position, 2-row receptacle with center strip contacts from the BM28 series, designed for FPC-to-board interconnects where board spacing is at a premium. At a 0.014" (0.35mm) pitch and a mated stacking height of 0.6mm, this connector fits into ultra-slim assemblies like smartphones, tablets, and wearables where every tenth of a millimeter counts. The gold-plated contacts (1.97µin) handle signal-level currents in a permanent or semi-permanent FPC connection — the light flash is adequate for the limited mating cycles typical of a factory-installed flex that stays mated through the product's life.
What the 0.35mm Pitch Means for Your Board Layout
The 0.35mm pitch is the tightest constraint on the board footprint — it drives trace width and spacing in the breakout region. With a 0.014" (0.35mm) centerline, you'll need fine-line PCB capability (typically 0.15mm trace / 0.15mm space or tighter) to route all 10 signals out of the connector footprint. The 2-row arrangement doubles the routing density per linear millimeter of board edge compared to a single-row FPC connector at the same pitch.
The official base product number is BM28B0.6, so any alternate suffix (like the (53) variant) shares the same pitch, height, and contact finish but may differ in packaging or reel orientation — verify the full order code against your BOM line before committing.
The BM28B0.6-10DS/2-0.35V(51) is the 10-position member; the series also offers 16-position (BM28B0.6-16DS/2-0.35V(53)) and 20-position (BM28B0.6-20DS/2-0.35V(51)) variants at the same 0.014" (0.35mm) pitch and 0.024" (0.61mm) height above board. All share gold contacts and solder retention.
