Frequently Asked Questions
What is the contact pitch and position count of the SFM-144-L2-LM-D-A-P, and how does this enable high-density designs?
The SFM-144-L2-LM-D-A-P has 88 positions arranged in a dual row at 1.27 mm (0.050 inch) pitch. This fine pitch allows significantly more signal contacts in a given PCB area compared to 2.54 mm pitch connectors, making it ideal for dense FPGA I/O interfaces, processor mezzanine cards, and compact embedded systems needing 88 reliable connections.
How does the high-reliability rating of the SFM-144-L2-LM-D-A-P benefit test fixtures and avionics designs?
High-reliability socket strips are rated for a high number of mating and unmating cycles with consistent contact resistance over their service life. For test fixtures and avionics boards where the 88-position connector may be mated hundreds or thousands of times, this rating reduces maintenance cost and the risk of intermittent connections compared to standard grade socket strips.
Is the SFM-144-L2-LM-D-A-P compatible with automated SMT assembly processes?
Yes. The SFM-144-L2-LM-D-A-P uses surface mount termination, which is compatible with standard reflow solder assembly processes. Its SMT footprint allows automated placement on high-density PCBs in production environments, including FPGA carrier boards, industrial I/O modules, and measurement instrument motherboards requiring 88-pin socket interfaces.
