Frequently Asked Questions
What is the contact pitch and row configuration of the SFM-145-T2-STL-D?
The SFM-145-T2-STL-D features a 0.050" (1.27 mm) pitch dual-row layout with 90 total positions (45 per row), enabling high-density connectivity in a compact surface mount footprint suitable for space-constrained PCB designs.
Which PCB assembly processes are compatible with the SFM-145-T2-STL-D surface mount socket strip?
The SFM-145-T2-STL-D is designed for standard SMT reflow soldering processes. Its surface mount termination style supports automated pick-and-place assembly with typical reflow temperatures up to 260°C, making it compatible with lead-free SAC305 solder paste manufacturing.
How does the SFM-145-T2-STL-D compare to through-hole socket strips for mezzanine board applications?
Compared to through-hole alternatives, the SFM-145-T2-STL-D offers a lower profile and smaller PCB footprint due to its SMT design. With 90 positions at 0.050" pitch, it provides high pin density on a single side of the board, eliminating drilling costs and enabling double-sided PCB utilization in mezzanine and module stacking applications.
What is the maximum number of signal connections available in the SFM-145-T2-STL-D?
The SFM-145-T2-STL-D provides 90 contact positions arranged in 2 rows of 45 pins each at 0.050" (1.27 mm) pitch. This configuration supports up to 90 independent signal, power, or ground connections per connector, making it suitable for wide data bus and multi-channel signal routing applications.
