Frequently Asked Questions
What stack height does SEAM-40-09.0-L-10-2-A-K-TR provide for mezzanine board designs?
The SEAM-40-09.0-L-10-2-A-K-TR provides a fixed 9.0 mm board-to-board stack height. This controlled spacing is critical in mezzanine designs where the distance between stacked PCBs must accommodate specific component heights or airflow requirements in chassis-enclosed systems.
How does the ELP (Eye of the Needle) termination on SEAM-40-09.0-L-10-2-A-K-TR differ from standard solder termination?
The Eye of the Needle (ELP) press-fit termination makes an interference fit into plated-through-holes in the PCB without solder, providing a gas-tight electrical connection at each of the 40 pins. This eliminates solder reflow heat stress and allows rework without desoldering, which is a key advantage in high-reliability aerospace and defense assembly processes.
What contact plating does SEAM-40-09.0-L-10-2-A-K-TR use and how does it affect signal integrity?
The connector uses gold (10 micro-inch) plated over nickel (50 micro-inch) on the mating contacts. Gold plating minimizes contact resistance and prevents oxidation, maintaining consistent electrical performance across all 40 contacts throughout the connector's rated mating cycle life in industrial and defense environments.
Is SEAM-40-09.0-L-10-2-A-K-TR RoHS compliant and what is the typical factory lead time?
Yes, SEAM-40-09.0-L-10-2-A-K-TR is RoHS compliant with a Pb-free designation. Samtec lists a factory lead time of approximately 1 week for standard orders, though buyers sourcing tape-and-reel volumes for production should confirm current availability with authorized Samtec distributors to plan BOM procurement accordingly.
