Alkaline copper plating can be applied directly to steel, copper alloys and zinc alloys, and the bonding of the plated layer is usually very good. However, when using alkaline copper plating additives, poor bonding can sometimes occur due to poor process operation or when the composition of the plating solution is not within the process range.
When using alkaline copper plating additives and poor bonding occurs, the first step is to determine whether it is caused before or during the copper plating process. How to determine? According to the experience of our engineers, you can take a part (the material is not problematic) and directly plated copper after a good pre-plating treatment.
If the bonding of the plated layer after such treatment is good, it indicates that the original bad bonding is caused by the poor treatment before plating, and vice versa is generated in the copper plating process. The following is a specific analysis of the possible causes of poor bonding of the plated layer and processing methods.
Incomplete degreasing before plating
The surface of the workpiece is stained with oil, to solve this problem, the electroplating plant needs to be strict process specifications and process parameters, reasonable setup of pre-treatment process, you can also set up organic solvents degreasing or increase the ultrasonic equipment, strengthen the degreasing operation and the process of inspection to ensure that the operation of the workers have to do it seriously.
