Frequently Asked Questions
What contact plating specification does SEAM-40-09.0-S-06-2-A-K-TR use, and why does 30 µin gold matter for high-speed signal links?
The SEAM-40-09.0-S-06-2-A-K-TR uses 30 microinches of gold over 50 microinches of nickel contact plating. The 30 µin gold thickness provides a robust, oxidation-resistant mating surface that maintains contact resistance below 20 milliohms across hundreds of mating cycles and temperature excursions from -55°C to +125°C, which is critical for multi-GHz differential pairs found in PCIe, SATA, and custom SerDes links in high-speed board stacking assemblies.
How does the 9.0 mm board stacking height of SEAM-40-09.0-S-06-2-A-K-TR affect mezzanine card design clearances?
A 9.0 mm board-to-board separation provides sufficient clearance for standard mid-height SMD components such as 4 mm tall electrolytic capacitors, low-profile voltage regulators, and crystal oscillators on the inner-facing PCB surfaces. Designers should add a minimum 1.0 mm margin above the tallest component height on both boards to avoid contact during thermal expansion, as PCB warpage at operating temperatures can reduce the effective gap by 0.2 to 0.5 mm in 40-position connector arrays.
What is the procurement lead time for SEAM-40-09.0-S-06-2-A-K-TR, and how should buyers plan for tape-and-reel production orders?
The SEAM-40-09.0-S-06-2-A-K-TR has a factory lead time of approximately 6 to 7 weeks from SAMTEC. Tape-and-reel packaging means the minimum order is typically one full reel, commonly 500 to 1000 pieces. Production buyers should place orders 8 to 10 weeks before the first assembly date and maintain a 2-week safety stock given that specialized high-density board stacking connectors with 30 µin gold plating have limited spot distribution inventory.
Which SAMTEC mating connector is compatible with SEAM-40-09.0-S-06-2-A-K-TR for a complete board stacking assembly?
The SEAM series mates with SAMTEC's SEAF or compatible receptacle series designed for the same 9.0 mm stacking height and 40-position single-row configuration. The ELP (Ergonomic Lead-in Profile) feature on the SEAM-40-09.0-S-06-2-A-K-TR provides self-guiding contact lead-ins that reduce mis-insertion force and prevent pin damage during blind-mate assembly, which is especially valuable in rack-mounted systems where visual alignment of 40 contacts at 2.54 mm pitch is difficult.
