Frequently Asked Questions
How many positions and what pitch does the SFM-142-L2-FM-D offer?
The SFM-142-L2-FM-D provides 84 positions arranged in a dual-row layout with a 0.050" (1.27 mm) pitch, giving 42 contacts per row. This extremely high-density configuration allows designers to consolidate over 84 signal lines into a surface mount connector with a footprint far smaller than equivalent 0.100" pitch alternatives, reducing board area and improving routing efficiency.
For which types of board-to-board connections is the SFM-142-L2-FM-D best suited?
The SFM-142-L2-FM-D excels in backplane-to-daughter-card, mezzanine, and FPGA-to-I/O-expansion board connections where 84 signals must pass between PCBs in a compact assembly. Its 0.050" pitch dual-row SMT design is ideal for high-speed digital data buses, analog multiplexer inputs on 8-channel or 16-channel measurement systems, and any stacked-board architecture requiring reliable high pin-count interconnects.
What is the reflow compatibility and assembly process for the SFM-142-L2-FM-D?
The SFM-142-L2-FM-D is designed for standard SMT reflow assembly, compatible with lead-free solder profiles up to 260 °C peak temperature per IPC/JEDEC J-STD-020 guidelines. Its surface mount leads support solder paste stencil printing and automated pick-and-place placement, streamlining high-volume assembly for the 84-position footprint and ensuring consistent solder joint quality across all contacts.
