Frequently Asked Questions
How many contacts does the QSE-020-01-C-D-A-K provide and at what pitch?
The QSE-020-01-C-D-A-K provides 40 positions in a dual-row (2x20) arrangement with 0.050" (1.27 mm) pitch. The 0.838" body length fits within compact PCB footprints, making this board stacking socket suitable for FPGA daughter boards and mezzanine modules where high contact density in a small area is required.
What role does the peg mounting option play in the QSE-020-01-C-D-A-K assembly process?
The PEG mounting option provides mechanical pegs that insert into corresponding PCB holes, anchoring the QSE-020-01-C-D-A-K connector body securely before reflow soldering. This prevents the 40-position socket from shifting during pick-and-place and reflow processes, ensuring accurate alignment with the mating board stacking connector and reducing defects in high-volume assembly.
Which mating connector mates with the QSE-020-01-C-D-A-K in a board stacking application?
The QSE-020-01-C-D-A-K socket mates with SAMTEC's QSH series board stacking plug headers at the same 0.050" (1.27 mm) pitch and 40-position dual-row configuration. The tin-over-nickel contact finish on both connector bodies ensures reliable electrical contact with low mating force across the specified number of mate-unmate cycles.
Is the QSE-020-01-C-D-A-K suitable for lead-free PCB assembly with automated placement equipment?
Yes, the QSE-020-01-C-D-A-K includes a pick-and-place pad feature that provides a flat surface for vacuum nozzle placement, enabling automated SMT assembly. The tin-over-nickel contact finish is compatible with RoHS-compliant lead-free reflow soldering processes at standard peak temperatures above 250°C, and SAMTEC quotes a factory lead time of approximately 2 weeks 4 days for bulk orders.
