Frequently Asked Questions
What signal capacity and pitch does SFM-136-L2-L-D-A-P-TR provide for mezzanine card designs?
The SFM-136-L2-L-D-A-P-TR provides 72 signal positions in a dual-row layout at 0.050" (1.27 mm) pitch, fitting a PCB footprint of approximately 46.4 mm length. This density suits FMC mezzanine card designs compliant with VITA 57.1, embedded computing modules, and high-speed signal processing boards requiring many parallel signal channels within limited board area.
How does the L2 solder tail variant of SFM-136 differ from T2 tails in terms of SMT assembly requirements?
The L2 solder tail on SFM-136-L2-L-D-A-P-TR provides a longer lead length compared to T2 tails, accommodating slightly thicker PCB solder mask clearances and improving solder joint robustness during reflow at up to 260°C. L2 tails suit designs where additional solder fillet height is needed for mechanical reliability, particularly on boards experiencing thermal cycling from -40°C to +85°C in industrial or aerospace applications.
Why is tape-and-reel packaging important for SFM-136-L2-L-D-A-P-TR in high-volume production environments?
Tape-and-reel (TR) packaging for SFM-136-L2-L-D-A-P-TR ensures each connector is individually pocketed in carrier tape on standard reels, enabling automated SMT pick-and-place feeders to place parts accurately at rates exceeding 10,000 placements per hour. This eliminates manual handling of the 72-position dual-row socket strip and reduces misalignment errors that could damage the 1.27 mm pitch contact array during high-volume PCB assembly.
