Frequently Asked Questions
What pitch and position count does the SFM-128-T2-H-D-A-P-TR socket strip provide?
The SFM-128-T2-H-D-A-P-TR provides 56 positions arranged in a dual-row configuration on a 0.050" (1.27 mm) pitch, offering 28 positions per row. This fine pitch allows designers to route high pin-count signals within a board area significantly smaller than standard 0.100" pitch connectors, making it ideal for high-density FPGA and processor module interfaces.
For what environmental or reliability classes is the high-reliability (H) grade rating appropriate?
The high-reliability (H) grade designation on the SFM-128-T2-H-D-A-P-TR indicates enhanced contact finish and tighter manufacturing tolerances that meet requirements for military, aerospace, and medical-grade applications. These connectors are typically rated for operating temperatures from -55°C to +125°C and are designed to withstand 500 or more mating cycles without significant contact resistance degradation.
How does the 0.050" pitch of SFM-128-T2-H-D-A-P-TR compare to standard 0.100" pitch connectors in board space savings?
The 0.050" (1.27 mm) pitch of the SFM-128-T2-H-D-A-P-TR occupies approximately half the linear board space per position compared to standard 0.100" (2.54 mm) pitch connectors, enabling a 56-position dual-row interface in roughly the same footprint as a 28-position 0.100" connector. This density advantage is critical in compact PCBs for portable instruments, small-form-factor computers, and mezzanine card interconnects.
Which SMT assembly processes are compatible with this SAMTEC socket strip?
The SFM-128-T2-H-D-A-P-TR is designed for surface mount reflow soldering and is supplied in tape-and-reel (TR) format compatible with standard automated pick-and-place equipment. It withstands lead-free reflow peak temperatures up to 260°C per J-STD-020, and its SMT terminations are coplanar to within standard tolerances to ensure reliable solder joint formation across all 56 positions in a single reflow pass.
