What this 10-position SMT header does on the board
The B10B-PH-SM4-TB is a 10-position, single-row SMT header from JST's PH series, pitched at 2.00 mm.
Mounting and footprint details for the layout
Surface-mount termination with solder retention pads — the two extra hold-downs at each end anchor the header during reflow and resist peel forces from the mated cable. The contact mating length is 3.30 mm, which gives a solid wipe before the detent clicks in.
