Frequently Asked Questions
How many contact positions does the SFM-142-T2-STL-D provide, and what is its pitch?
The SFM-142-T2-STL-D provides 84 contact positions arranged in a dual-row layout at a 0.050" (1.27 mm) pitch. This high pin count in a compact footprint makes it suitable for applications requiring dense signal routing within a constrained PCB area.
What soldering process is recommended for the SFM-142-T2-STL-D?
The SFM-142-T2-STL-D uses surface-mount (SMT) termination, making it compatible with standard reflow soldering processes at peak temperatures up to approximately 260°C. This supports automated pick-and-place assembly commonly used in high-volume electronics manufacturing, improving throughput and solder joint consistency compared to hand soldering.
For what types of systems is an 84-position socket like the SFM-142-T2-STL-D a better fit than a lower pin-count connector?
An 84-position socket is preferred in systems with many parallel data, control, or power signals that need to be routed between boards or modules, such as FPGA daughter cards, backplane connections, or large sensor arrays. Using a single 84-pin connector at 1.27 mm pitch instead of multiple smaller connectors reduces the number of assembly steps and connector-to-connector alignment issues.
What distinguishes the SFM series from standard low-cost socket strips?
The SAMTEC SFM series is built to high-reliability standards, featuring precision-machined contacts with gold plating for low and stable contact resistance across thousands of mating cycles. Unlike generic socket strips, the SFM-142-T2-STL-D is rated for demanding environments including aerospace and military electronics where connector failure is not acceptable.
