The alkaline copper plating process is a common surface treatment, but rough plating is a vexing problem when using alkaline copper plating additives. Understanding the causes of these problems is important for improving the quality of the plated layer.
First of all, one of the main reasons for rough plating is the presence of impurities in the plating solution. During alkaline copper plating, the accumulation of impurities affects the uniformity of the plating solution, which in turn leads to rough plating. Common impurities such as metal impurities, oil contaminants and oxides can adversely affect the plating solution. In order to remove these impurities, proper purification methods are necessary.
Secondly, the unbalanced ratio of components in the plating solution can also lead to rough plating. Potassium salt plays a stabilizing role in the cyanide copper plating solution and can improve the performance of the plating solution. By adjusting the concentration of potassium salt appropriately, the uniformity and brightness of the plated layer can be improved. Especially when the ratio of the components of the plating solution is not controlled properly, adjusting the concentration of potassium salt can improve the performance.
The use of good alkaline copper plating additives such as Bigely Cu-201 is also an effective solution to the problem of rough plating.Cu-201 Alkaline Copper Brightener is characterized by a wide operating range, good covering ability, etc., and is capable of obtaining copper plating with detailed crystallization and uniform bright copper coatings. It is suitable for workpieces with different substrates such as steel, copper, bronze and zinc alloy castings, and can improve the quality of the plating layer. By optimizing the composition of the plating solution, Cu-201 can effectively reduce the probability of roughness of the plated layer and enhance the overall surface treatment effect.
