Frequently Asked Questions

How many signal positions does STMM-110-02-S-D-SM-K-TR support and at what pitch?

STMM-110-02-S-D-SM-K-TR features 20 positions in a dual-row configuration (10 per row) on 0.050-inch (1.27mm) pitch. The 1.023-inch body length accommodates these contacts in a compact rectangular layout, supporting dense signal routing between a baseboard and daughter module at a standardized SAMTEC pitch.

What termination finish does the STMM-110-02-S-D-SM-K-TR use and how does it affect soldering?

The connector uses tin (Sn) over nickel (Ni) barrier termination on its square pin-socket contacts. This finish is compatible with standard SAC305 lead-free reflow profiles at peak temperatures up to 260°C, ensuring good wettability and reliable solder joint formation during surface-mount assembly in production environments.

Is STMM-110-02-S-D-SM-K-TR packaged for automated assembly, and what is the lead time?

Yes, the -TR suffix designates tape-and-reel packaging compatible with standard 8mm or 12mm feeder systems for automated pick-and-place machines. The factory lead time is approximately 1 week from authorized SAMTEC distributors, with the 0.237-inch body breadth fitting standard component trays used in high-volume PCB assembly operations.

Which embedded module designs benefit from using STMM-110-02-S-D-SM-K-TR as the board connector?

Embedded computing daughter cards, FPGA mezzanine modules, and wireless radio boards benefit from STMM-110-02-S-D-SM-K-TR due to its 20-position dual-row SMT footprint that fits standard 0.050-inch grid layouts. The 0.24-inch body depth keeps stack height low, important for designs targeting total assembly heights under 10mm in portable or panel-mounted industrial devices.
