You'll need fine-line traces between pads and a stack-up that keeps signal integrity through the mezzanine link. That gap is fixed — no adjustment if your enclosure has tighter clearance.","metaTitle":"Hirose BM20B(0.8)-34DP-0.4V(53), 34 Pos, 0.40mm Pitch","metaDescription":"Hirose BM20 series header, 34 positions, 0.016\" (0.40mm) pitch, 0.8mm stacking height, gold contacts.
