Frequently Asked Questions
What makes the Tiger Eye contact system in the TFC-110-02-L-D-A superior to standard stamped contacts?
The Tiger Eye system uses a formed-beam contact geometry that maintains consistent normal force of approximately 50 grams per pin across 100 or more mating cycles, compared to standard stamped contacts that can lose compliance after 20-30 insertions. The gold (10 µin) over nickel (50 µin) plating adds corrosion resistance, extending reliable electrical performance in humid or mildly corrosive operating environments.
How does the shrouded housing of TFC-110-02-L-D-A aid PCB assembly and field service?
The shroud around the 20-position dual-row contacts acts as a mechanical guide during mating, reducing mis-alignment forces that could damage 10 µin gold plating. In field service environments where boards are swapped without fixtures, the 1.125" body length shroud keeps all 20 pins protected from accidental side-loading, preventing bent contacts and extending connector service life beyond 50 insertion cycles.
For a compact FPGA mezzanine card running at 3.3 V logic, is TFC-110-02-L-D-A suitable?
Yes. The TFC-110-02-L-D-A board-stacking connector handles signal voltages up to standard CMOS levels including 3.3 V across its 20 dual-row positions. The dual-row layout provides 20 signal or power pins in a 1.125" body length footprint, and the gold-plated contacts maintain contact resistance below 20 mΩ over the rated mating cycles, ensuring clean signal transitions for FPGA I/O interfaces at speeds up to several hundred MHz.
How does the RoHS-compliant tin-over-nickel termination finish affect soldering of TFC-110-02-L-D-A?
The tin (Sn) over nickel (Ni) barrier termination is fully compatible with standard lead-free reflow profiles peaking at 260 °C, and the nickel barrier prevents tin diffusion into the copper contact base that could degrade solder joint strength over time. This makes the TFC-110-02-L-D-A suitable for RoHS-compliant production lines without special flux or alloy accommodations.
