Its defining dimensions are the 0.016\" (0.40mm) pitch and a mated stacking height of 1.5mm — the tight pitch packs 70 signal lines into a compact footprint, while the 1.5mm stack height sets the board spacing in a portable or handheld assembly where z-height is at a premium. ## Mating and Board Layout The 0.40mm pitch demands precise PCB land pattern alignment; the recommended footprint is available in the Hirose product drawing. The SMT pads are laid out in a dual-row staggered pattern to maintain signal integrity through the mezzanine connection.","metaTitle":"Hirose DF40C-70DS-0.4V(51) Receptacle, 70 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-70DS-0.4V(51) receptacle, 70 positions, 0.40mm pitch, 1.5mm stacking height.
