Frequently Asked Questions
What pitch and contact count does the SFM-144-L2-STL-D-A-K provide?
The SFM-144-L2-STL-D-A-K features a 0.050" (1.27 mm) pitch dual-row configuration with 144 contacts total, arranged in 2 rows of 72 pins. This fine-pitch layout supports high-density board-to-board interconnections in compact PCB designs where space is at a premium.
Which board-to-board applications benefit most from this SAMTEC socket strip?
This connector is ideal for FPGA daughtercard interfaces, industrial backplane assemblies, and test-and-measurement systems requiring 144 reliable signal paths at 1.27 mm pitch. The dual-row surface-mount design supports automated reflow soldering, making it well suited for high-volume production environments that demand consistent electrical performance across hundreds of contacts.
How does the stainless-steel hardware (STL suffix) affect the reliability of this connector?
The STL stainless-steel hardware provides superior corrosion resistance compared to standard plating options, extending connector service life in humid or chemically active environments. Combined with SAMTEC's high-reliability construction rated for repeated mating cycles, the stainless-steel option maintains dimensional stability and contact normal force over the full -55°C to +125°C operating temperature range.
Can the SFM-144-L2-STL-D-A-K be reflowed using standard SMT processes?
Yes. The surface-mount termination style is compatible with standard 260°C peak reflow profiles used in automated SMT assembly lines. The 0.050" (1.27 mm) pitch lands can be accurately registered with solder paste stencils, and the component's tape-and-reel (-TR) packaging variant supports pick-and-place equipment for high-throughput production runs.
