Frequently Asked Questions
How many positions and rows does the SFM-133-L2-SM-D-A-K provide and what is its pitch?
The SFM-133-L2-SM-D-A-K is a 66-position dual-row socket strip with a 0.050 inch pitch, delivering high-density interconnection in a compact surface mount footprint suitable for space-constrained board-to-board designs.
What PCB assembly process is the SFM-133-L2-SM-D-A-K optimized for?
This connector is designed for surface mount assembly, making it compatible with standard SMT reflow soldering processes. Its 0.050 inch pitch and dual-row layout with 66 pins supports automated pick-and-place and reflow in high-volume production environments.
Which types of systems benefit from the SFM-133-L2-SM-D-A-K's high-reliability socket design?
Telecom line cards, industrial compute modules, FPGA mezzanine boards, and backplane systems benefit from this connector's 66-position dual-row high-reliability design, which ensures stable 0.050 inch pitch signal connections across thousands of mating cycles.
When is SFM-133-L2-SM-D-A-K a better choice than a through-hole equivalent connector?
The SMT version is preferred when board thickness is limited or when wave soldering is not available, since its surface mount termination eliminates through-hole drilling while still providing 66 positions at 0.050 inch pitch for high-count signal routing.
