Frequently Asked Questions

What stacking height and contact finish does the SEAM-20-03.5-S-06-2-A-K-TR provide?

The SEAM-20-03.5-S-06-2-A-K-TR provides a 3.5 mm board stacking height with contacts finished in 30 micro-inch gold over 50 micro-inch nickel. The gold finish ensures low contact resistance and excellent corrosion resistance, supporting reliable electrical performance across multiple mating cycles in board stacking applications with tight height constraints.

How does the peg mounting feature of SEAM-20-03.5-S-06-2-A-K-TR improve assembly quality?

The peg board mounting option mechanically anchors the SEAM-20-03.5-S-06-2-A-K-TR to the PCB through alignment pegs that fit into corresponding holes on the board. This prevents connector movement during reflow soldering, ensuring all 20 contacts maintain proper pad registration and eliminating misalignment defects in high-volume automated assembly operations.

For which system types is the SEAM-20-03.5-S-06-2-A-K-TR a preferred stacking interconnect choice?

The SEAM-20-03.5-S-06-2-A-K-TR is preferred for board stacking in compact embedded computing modules, mezzanine add-in cards, and wireless communication modules where a 3.5 mm stack height and 20-position signal capacity are required. Its SAMARRAY and ELP features also make it compatible with SAMTEC high-density array connector ecosystems used in telecom blades and FPGA evaluation kits.
