Frequently Asked Questions
What distinguishes the formed (F) termination on SFM-129-T2-F-D-K-TR from standard straight-lead SMT terminations?
The formed (F) termination on this 58-position SAMTEC socket bends the contact leads to a specific geometry that improves solder fillet formation during SMT reflow at standard reflow temperatures. This enhances mechanical pull strength and electrical contact reliability compared to straight-lead terminations, particularly important in vibration-prone industrial environments.
How many signal positions can the SFM-129-T2-F-D-K-TR accommodate in a dual-row SMT layout?
The SFM-129-T2-F-D-K-TR provides 58 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch. This high contact count in a compact surface mount footprint enables routing of 58 independent signal or power channels between stacked boards, reducing the total connector count needed for complex embedded system interconnects.
Why is T2 tape-and-reel the recommended packaging for SFM-129-T2-F-D-K-TR in production environments?
T2 tape-and-reel packaging for SFM-129-T2-F-D-K-TR is sized to accommodate the 58-pin SMT connector body precisely in the carrier tape pockets, preventing movement during reel transport and ensuring reliable pick-and-place accuracy. This reduces placement defects compared to bulk or tray packaging in automated high-volume SMT assembly lines.
