Ultra-Fine-Pitch Mezzanine Plug for Tight Stack Heights
Its 0.016" (0.40mm) pitch and dual-row layout pack 34 circuits into a footprint that fits between a smartphone battery and the main PCB — the pitch drives trace-and-space routing at the board layout stage. Mated stacking height is 0.8mm, with the connector sitting just 0.027" (0.68mm) above the board surface, making it suited for ultra-slim products where every tenth of a millimeter of z-height is budgeted against the enclosure wall.
Contact Plating and Solder Retention for Reflow Assembly
Surface-mount termination with these retention features means the part can run through a standard lead-free reflow profile without tombstoning or shifting.
