Frequently Asked Questions
What stack height and position count does SEAM-20-11.0-S-08-2-A-K-TR support for board stacking?
The SEAM-20-11.0-S-08-2-A-K-TR provides an 11.0 mm board stacking height with 160 positions at 0.050" (1.27 mm) pitch. This combination makes it well-suited for compact, high-density board stacking in FPGA mezzanine cards, computing blades, and high-performance networking line cards.
How do the ELP contacts in SEAM-20-11.0-S-08-2-A-K-TR benefit high-speed signal designs?
The ELP (Eye of the Needle) contacts in SEAM-20-11.0-S-08-2-A-K-TR incorporate Final Inch impedance control technology, which minimizes signal reflection and crosstalk at multi-gigabit data rates. This is essential for 160-position board stacking applications in high-speed computing and communications equipment where signal integrity across all channels must be maintained.
What is the lead time for SEAM-20-11.0-S-08-2-A-K-TR and how should procurement teams plan orders?
The factory lead time for SEAM-20-11.0-S-08-2-A-K-TR is 1 week, which is exceptionally short for a 160-position high-density board stacking connector. Procurement teams can rely on quick turnaround for prototype and production orders, though the tape-and-reel format and specialized SEARAY interface may require minimum order quantity commitments.
Is SEAM-20-11.0-S-08-2-A-K-TR RoHS compliant and lead-free for use in modern electronic assemblies?
Yes. The SEAM-20-11.0-S-08-2-A-K-TR is lead-free and RoHS compliant as indicated by its Pb-free code. This makes it fully compatible with modern lead-free SMT assembly processes, including SAC305 solder reflow, for all 160 positions at the 1.27 mm pitch board stacking interface.
