Types of Copper Plating KPW Offers
Acid copper provides excellent leveling, high macro-throwing power, and high plating speeds. However, acid copper does have limitations. Some metals, such as steel and aluminum, are attacked and etched by the acidic solution. It can also produce immersion deposits that have very poor adhesion. For these metals, a cyanide copper strike must be used prior to plating.
Cyanide copper is essential for copper plating on steel, zinc, and aluminum because it adheres well to them and minimizes immersion deposits. Cyanide copper has excellent throwing power which leads to less thickness variations. This is extremely important when dealing with parts that have complicated shapes.
