Frequently Asked Questions
What is the pitch and row configuration of the SFM-140-L2-F-D-A-K?
The SFM-140-L2-F-D-A-K features a dual-row configuration with 80 positions total on a 0.050" (1.27 mm) pitch. This compact spacing allows high-density signal routing in space-constrained PCB designs, making it suitable for applications requiring 40 pins per row in a surface mount footprint.
Which PCB assembly processes are compatible with the SFM-140-L2-F-D-A-K socket strip?
The SFM-140-L2-F-D-A-K uses surface mount technology (SMT) termination, making it fully compatible with automated reflow soldering assembly processes. Its 1.27 mm pitch footprint aligns with standard SMT pick-and-place equipment, supporting high-volume production lines while maintaining reliable solder joint integrity across the 80 positions.
How does the SFM-140-L2-F-D-A-K compare to through-hole alternatives for backplane interconnects?
Unlike through-hole connectors that require wave soldering or hand assembly, the SFM-140-L2-F-D-A-K's surface mount design reduces PCB layer requirements by eliminating plated through-holes, saving board space. The 0.050" pitch and 80-position dual-row arrangement deliver comparable signal density while enabling double-sided component placement on boards as thin as 1.6 mm.
