The pyrophosphate copper plating process originated in 1847. In subsequent research and production applications, it has continuously demonstrated its advantages. It is not only applicable to the production of electroformed products but also to steel and aluminum materials. In this article, we will analyze the functions of each component, including the copper pyrophosphate additive.
Ammonium hydroxide
Adding a small amount of ammonium hydroxide can make the produced coating more uniform and brighter, and also promote the dissolution of the anode. Excessive ammonium hydroxide can lead to the formation of cuprous oxide, reducing the adhesion of the coating.
Because ammonia is volatile, it needs to be added every day. The amount added depends on the size of the tank. Generally speaking, electroplating plants can guide the addition based on the results of chemical analysis. When the solution temperature, pH value and ammonia concentration in the solution increase, ammonia will also be consumed, and the two show a positive correlation. However, the current has little effect on the consumption.
Copper pyrophosphate additive
Copper pyrophosphate additives play a significant role in electroplating solutions and have a greater impact on the coating than any other process parameters. Controlling or limiting its concentration helps to refine the grain structure of the coating, obtain the tensile strength and toughness of the coating that meet the customer's requirements, bring a leveling effect to the solution, and enable it to play the role of a brightener.
