WebJan 5, 2024 · Key similarities and differences of Pd and Ni in catalytic systems are discussed. Overall, Ni and Pd catalyze a vast number of similar C–C and C–heteroatom bond-forming reactions. However, the smaller atomic radius and lower electronegativity of Ni, as well as the more negative redox potentials of low-valent Ni species, often provide … http://jx-plating.com/tech_EPP-I.html

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 ... WebElectroless Ni / Pd / Au Plating (ENEPIG) Piezo-electrical thin films. Semiconductor manufacturers usually rely on Aluminum and in some rare cases Copper as contact metallization. Unfortunately, Aluminum cannot be soldered and the copper is usually not thick enough for a reliable solder connect. A very efficient way to gain a solderable ...
