Frequently Asked Questions
How many signal positions does the SFM-144-L2-L-D-A-K provide, and what is the contact pitch?
The SFM-144-L2-L-D-A-K provides 144 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch, enabling high-density signal routing on surface-mount PCBs. This compact pitch is ideal for space-constrained designs requiring many simultaneous connections.
For which PCB assembly processes is the SFM-144-L2-L-D-A-K socket strip designed?
The SFM-144-L2-L-D-A-K is a surface-mount (SMT) component compatible with standard reflow soldering processes. Its SMT footprint supports automated pick-and-place assembly, and its 0.050" pitch accommodates fine-pitch PCB pad layouts common in high-density designs with 144 pins.
When would SFM-144-L2-L-D-A-K be preferred over a through-hole equivalent for board-to-board interconnects?
The SFM-144-L2-L-D-A-K is preferred when PCB real estate is critical, as its surface-mount 0.050" pitch occupies significantly less board space than a through-hole 144-position connector. It also supports double-sided assembly, making it ideal for compact industrial and telecom boards where component density exceeds 100 connections per square inch.
