Frequently Asked Questions
What pitch and row configuration does the SFM-144-02-L-D-A-K use?
The SFM-144-02-L-D-A-K uses a 0.050-inch (1.27 mm) pitch in a dual-row layout, providing 144 positions total. This tight pitch enables high-density interconnects while keeping the PCB footprint compact and suitable for space-constrained designs.
Which PCB assembly processes are compatible with the SFM-144-02-L-D-A-K surface-mount termination?
The surface-mount termination of the SFM-144-02-L-D-A-K is compatible with standard SMT reflow soldering processes. Its footprint supports 0.050-inch pitch pad layouts, and the component withstands typical reflow temperatures up to 260°C, making it suitable for lead-free assembly lines.
In what type of systems is the SFM-144-02-L-D-A-K a good fit for mezzanine board interconnects?
The SFM-144-02-L-D-A-K is a strong choice for mezzanine and daughter-card interconnects in telecommunications, industrial control systems, and data communications equipment. Its 144-position, dual-row design supports parallel data buses with 72 signal pairs, enabling high-bandwidth connections between stacked boards.
How does the SFM-144-02-L-D-A-K compare to SAMTEC's single-row socket strips for connector density?
Compared to single-row socket strips with a similar 0.050-inch pitch, the SFM-144-02-L-D-A-K provides twice the position count per unit length by using a dual-row configuration. This results in 144 positions in roughly the same board length as a 72-position single-row strip, reducing PCB area by up to 50%.
