Frequently Asked Questions
What inter-board spacing does the 7.0 mm stack height of SEAM-40-07.0-S-06-2-A-K-TR define, and how does that constrain component height on the daughter card?
The 7.0 mm stack height sets the center-to-center board separation to 7.0 mm when the SEAM connector is mated with its receptacle. This limits the maximum height of components mounted on the daughter-card face closest to the motherboard to approximately 5.5 mm to 6.0 mm, accounting for solder joint and tolerance stack-up, making it compatible with low-profile capacitors, resistors, and thin QFN packages in dense board-stacking designs.
How does the 30 µin gold contact finish on SEAM-40-07.0-S-06-2-A-K-TR benefit applications with frequent board swaps?
Gold plating at 30 µin (microinches) over 50 µin nickel provides a hard, oxide-free contact surface that maintains contact resistance below 20 mΩ across hundreds of mating cycles. For field-replaceable line cards or modular computing boards that are swapped monthly during maintenance, the 30 µin gold finish significantly outlasts the 5 µin to 10 µin flash-gold finish used on cost-optimized connectors, reducing signal degradation over the product's service life.
Which SAMTEC technologies on SEAM-40-07.0-S-06-2-A-K-TR improve signal integrity for multi-gigabit board-stacking interfaces?
This part integrates SAMTEC's SEARRAY technology, which provides a controlled-impedance signal path optimized for differential pair routing at data rates above 10 Gbps, and ELP (Edge Launch Pin) geometry that reduces stub effects at high frequencies. Together, these features keep insertion loss below 1 dB at 15 GHz for 80-position stacking connectors, supporting PCIe, 100G Ethernet, and similar high-speed interfaces in networking and computing platforms.
How should procurement teams account for the 9-week lead time when planning production schedules for SEAM-40-07.0-S-06-2-A-K-TR?
With a factory lead time of approximately 9 weeks, buyers sourcing SEAM-40-07.0-S-06-2-A-K-TR should place purchase orders at least 10 to 12 weeks before the scheduled PCB assembly start, adding 1 to 2 weeks buffer for incoming inspection and inventory receiving. For programs with 6-month production ramps, blanket orders covering 3 to 6 months of forecast volume reduce per-unit lead-time risk and can improve pricing at quantities above 500 reels.
