Several measures to improve the stability of the electroless copper plating solution

In the previous article, we discussed some factors that contribute to the poor stability of the electroless copper plating solution. So, what methods should electroplating factories adopt to enhance its stability?

Use air agitation

During the application of the electroless copper plating solution, air stirring must be adopted. Because once the copper ions in the plating solution are reduced to cuprous oxide, the O2 in the air will oxidize the cuprous oxide into Cu2+ ions, thereby inhibiting the formation of copper powder resulting from the disproportionation reaction.

During the mixing process, the electroplating factory needs to follow the guidance of the electroless copper plating solution manufacturer, Bigely and take measures such as oil and dirt removal for the air added to the tank, because doing so can prevent oil and dirt from entering the plating solution.

Add stabilizers to the electroless copper plating solution

There are many commonly used stabilizers. However, when preparing the solution, the dosage of this substance must be strictly controlled. Because if the dosage exceeds the specified range, the electroless copper plating reaction will stop and the copper cannot be completely deposited.

Some electroplating factories aim to cut costs and choose to prepare their own chemical solutions. However, due to a lack of profound understanding of the functions of the chemical components, the solutions produced have problems such as poor stability. Frequent malfunctions occur on the production line, and instead of solving these issues, they have to spend time and energy to make adjustments, which is not worth it.
