Frequently Asked Questions
What is the contact material and mating finish of TFC-145-02-FM-D, and how does this affect long-term connector reliability?
The TFC-145-02-FM-D uses phosphor bronze contacts with a gold flash mating finish and tin-over-nickel termination finish. Gold flash on the mating surfaces provides corrosion resistance and low initial contact resistance, while the nickel barrier prevents tin whisker migration into the mating zone, supporting reliable performance over thousands of mating cycles in industrial environments.
How many positions does TFC-145-02-FM-D provide, and what mating connector should be paired for a complete board-stacking assembly?
The TFC-145-02-FM-D provides 90 positions in a dual-row layout at 0.050-inch (1.27 mm) pitch. It mates with SAMTEC SFM series socket strips of the same pitch and position count, creating a complete board-stacking interconnect. The pairing allows signal transmission between two PCBs separated by a configurable stack height.
Is TFC-145-02-FM-D suitable for wave solder or reflow assembly, and what termination finish is used?
The TFC-145-02-FM-D uses a tin (Sn) with nickel (Ni) barrier termination finish, which is compatible with both wave soldering and reflow soldering processes. The nickel barrier protects against intermetallic growth during reflow at peak temperatures up to 260°C, ensuring reliable solder joint formation across all 90 positions in the dual-row footprint.
When is TFC-145-02-FM-D the preferred choice over premium SAMTEC board-stacking connectors in a cost-sensitive design?
TFC-145-02-FM-D is specified when a design requires 90 positions at 0.050 inch pitch but the program has cost constraints that rule out higher-grade plating options. The Tiger Eye series delivers the same phosphor bronze contact base and dual-row 1.27 mm pitch geometry as premium lines, but at reduced unit cost, making it attractive for commercial-grade industrial I/O and telecom backplane applications.
