Frequently Asked Questions
What mating height and contact finish does the SEAM-50-02.0-S-04-2-A-K-TR provide for board stacking?
The SEAM-50-02.0-S-04-2-A-K-TR offers a 2.00 mm mating height with 30 microinch gold over 50 microinch nickel contact finish, providing excellent signal integrity and corrosion resistance for high-cycle board stacking applications in 50-position configurations.
How does the peg mounting option on the SEAM-50-02.0-S-04-2-A-K-TR improve SMT assembly yield?
The peg board mounting feature on the SEAM-50-02.0-S-04-2-A-K-TR mechanically locks the 50-pin connector to the PCB prior to reflow, preventing movement during the solder paste reflow process. This reduces misalignment defects in automated assembly lines and is especially valuable for the 2.696 inch body length at 2.00 mm stack height.
Which system architectures benefit most from the SEAM-50-02.0-S-04-2-A-K-TR's 50-position stacking design?
Server blades, FPGA mezzanine cards, defense avionics modules, and test and measurement backplanes benefit from the SEAM-50-02.0-S-04-2-A-K-TR's 50-position, 2.00 mm stack height. The gold contact finish supports repeated mating cycles and maintains low contact resistance across the 50 pins.
What procurement considerations apply when sourcing the SEAM-50-02.0-S-04-2-A-K-TR in tape-and-reel format?
The SEAM-50-02.0-S-04-2-A-K-TR is packaged in tape-and-reel (TR suffix) for automated pick-and-place assembly. Buyers should confirm minimum reel quantity (MOQ), lead time, and RoHS certification before committing to volume orders on this 50-position board stacking connector with 2.00 mm height.
