Frequently Asked Questions
What contact finish does the TFM-140-32-S-D-P use, and why does it matter for reliability?
The TFM-140-32-S-D-P uses gold over nickel mating contact finish on its Tiger Eye contacts and tin over nickel on the termination side. Gold plating provides a noble metal mating surface with contact resistance typically below 20 milliohms and excellent corrosion resistance across thousands of mating cycles, making it suitable for high-reliability interconnects in defense, aerospace, and test equipment where signal integrity across 80 positions must be maintained over the product lifetime.
How does the TFM-140-32-S-D-P's Tiger Eye contact design improve mating reliability?
SAMTEC's Tiger Eye contact technology uses a dual-beam wiping contact geometry that makes two independent electrical contact points per pin, reducing the probability of an open circuit due to contamination or slight misalignment. For an 80-position 1.27 mm pitch connector like the TFM-140-32-S-D-P, this dual-beam design maintains low contact resistance across all 80 positions even after repeated mating cycles or exposure to vibration environments.
What is the significance of the pick-and-place pad on the TFM-140-32-S-D-P for SMT production?
The integrated pick-and-place pad on the TFM-140-32-S-D-P provides a flat vacuum-grippable surface for automated SMT pick-and-place machines, ensuring accurate placement of the 2.125-inch long 80-position connector body on the PCB pad pattern. Without this feature, placing a connector of this size accurately at 1.27 mm pitch on an automated line would require custom tooling, increasing setup costs and placement error rates in high-volume production.
In which high-speed or high-reliability board designs is the TFM-140-32-S-D-P most appropriate?
The TFM-140-32-S-D-P is most appropriate for high-speed mezzanine connections in FPGA carrier boards, processor modules, and communications line cards where 80 signals at 1.27 mm pitch must transition between PCBs with minimal insertion loss. Its gold contact finish supports signal frequencies above 1 GHz with low contact resistance, and the surface mount vertical orientation maintains a compact 0.44-inch depth profile suitable for stacked card assemblies in 1U and 2U rack equipment.
