2 Layer Teflon Rigid PCB with ENIG Finish

Another beneficial product offered by Rigiflex is the 2 layer Teflon PCB with ENIG finish. Teflon is a non-viscous material, which can remain stable in high temperatures applications. It is also resistant to heat, moisture, abrasion, and corrosion. The second beneficiary feature is the surface finish Electro Nickel Immersion Gold (ENIG). It provides a flat and level finish, and the immersion gold protects the nickel from oxidation. ENIG is also easy to use in the PCB manufacturing process, especially during circuit board soldering. The combination of Teflon and ENIG results in a PCB with an organic base material that is capable of preventing low conductivity and circuit loss.
