Plating on Aluminum Substrates for Power

Traditional Techniques for Plating on Aluminum. Plating aluminum is a much more involved process than that of traditional engineering materials such as steel and copper. The reason for this lies also with the reactivity of aluminum; aluminum very readily wants to react with the oxygen in the atmosphere forming oxides on the surface.

Electroless Ni / Pd / Au Plating (ENEPIG)

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 metallization is the electroless deposition of a Nickel diffusion barrier.

Although if you wanted to trade costs, consider giving-up nickel to 150uin thickness, while increasing the gold thickness. Gold over electroless nickel creates brittle joints because of phosphorous in the nickel plating bath. The phosphorous migrates into the over-plating. Electrolytic nickel and gold plating should not be a problem.
