Board-Stacking Fit: 0.35 mm Pitch, 0.6 mm Stack Height
The 0.014" (0.35 mm) pitch packs 20 circuits into a dual-row footprint that forces a fine-line PCB layout — expect trace-and-space limits below 0.18 mm on the inner layers to route all signals out of the connector zone. Mated stacking height is 0.6 mm, which means the two PCBs sit nearly flush; this suits handheld, wearable, or camera-module assemblies where every tenth of a millimetre of clearance is allocated elsewhere.
Solder Retention and SMT Assembly
The plug body includes solder retention features — small metal tabs or barbs that reflow into the solder fillet alongside the signal contacts. On a 0.35 mm pitch part with no through-hole anchors, those retention features are what keep the connector from lifting off the pad during the reflow oven or from shearing off when the mated board stack is handled. The surface-mount termination is the only mounting option; no press-fit or through-hole variant exists in this series at this pitch.
