Frequently Asked Questions
How many positions does the SFM-134-02-STL-D-A-K provide, and at what pitch are they arranged?
The SFM-134-02-STL-D-A-K provides 68 positions arranged in 2 rows at a 0.050" (1.27 mm) pitch. This high pin count and fine pitch combination enables routing a large number of signals across a compact SMT footprint, making it ideal for high-density board-to-board and mezzanine interconnect designs.
What does the STL suffix indicate on the SFM-134-02-STL-D-A-K, and how does it affect PCB assembly?
The STL suffix specifies the tail geometry of the connector's surface-mount terminations, providing an optimized stand-off height that ensures consistent solder joint formation during reflow assembly. This controlled stand-off distance helps maintain uniform solder paste volume under all 68 pins and improves assembly yield in automated SMT production lines.
For a high-speed FPGA daughter card design, why would an engineer choose the SFM-134-02-STL-D-A-K over a through-hole connector?
An engineer would choose the SFM-134-02-STL-D-A-K because its surface-mount design eliminates through-hole drilling, saving PCB fabrication cost and enabling routing on all layers beneath the connector area. The 68-position, 1.27 mm pitch layout provides a very high signal density in a smaller footprint than equivalent through-hole connectors, which is critical for compact FPGA module interfaces with many parallel data and control signals.
In what types of high-reliability systems is the SFM-134-02-STL-D-A-K commonly deployed?
The SFM-134-02-STL-D-A-K is commonly deployed in telecommunications base station hardware, networking switch fabric boards, defense electronics, FPGA-based computing accelerators, and industrial automation controllers where a 68-position, 1.27 mm pitch dual-row SMT socket provides reliable high-density board-to-board signal interconnect in demanding operating environments.
