Frequently Asked Questions
What contact finish does STMM-105-02-S-D-SM-K-TR use, and why does it matter for board-to-board reliability?
STMM-105-02-S-D-SM-K-TR uses 30 µin gold over 50 µin nickel as the mating contact finish, providing excellent corrosion resistance and low, stable contact resistance over thousands of mating cycles. The phosphor bronze base material adds spring compliance, ensuring consistent electrical contact across all 10 positions in compact dual-row SMT board-to-board connections.
For a space-constrained PCB, how small is the STMM-105-02-S-D-SM-K-TR body, and what pitch does it use?
STMM-105-02-S-D-SM-K-TR has a body length of 0.633 inch (approximately 16 mm) with a body depth of 0.24 inch, fitting a dual-row 10-position header into a very compact footprint. The connector uses a 2 mm pitch between positions, enabling dense board-to-board layouts in handheld instruments, wearable modules, and compact embedded computing boards.
Which soldering process does STMM-105-02-S-D-SM-K-TR support, and what termination finish is used on the PCB pads?
STMM-105-02-S-D-SM-K-TR is designed for surface mount assembly, with termination contacts finished in tin (Sn) over a nickel (Ni) barrier layer for reliable solder joint formation during reflow at peak temperatures up to 260°C. The SMT termination style eliminates through-hole vias, saving board space and simplifying PCB fabrication for high-volume automated production runs.
