WebNov 21, 2024 · The expectation is that Ni corrosion would not occur in ENEPIG, as the Au ions have no direct access to the Ni. This would be true if the Pd layer is impervious to the Au ions. If the Pd layer is thinner (1 to 4µin/0.025 to 0.1µm), it is not totally impervious, and the Au ions may have access to the underlying Ni, offering an easier path to ...
