The Hirose BM23FR0.8-18DP-0.35V(895) is an 18-position, dual-row header from the BM23 series, using a 0.014" (0.35mm) pitch. This is the tightest pitch in the BM23 family, so the PCB footprint must be laid out with fine trace widths and tight spacing — expect 0.18mm to 0.20mm trace/space on the inner layers to route out all 18 signals. The mated stacking height is 0.8mm, which sets the board-to-board gap in a mezzanine configuration; the 0.025" (0.63mm) height above board means the connector sits low, leaving clearance for components on the underside of the top board. Gold flash (1.97µin) on the contacts handles the few mating cycles typical of a production assembly — it is not specced for repeated field reconnects.
