In acid tin plating process, the plating solution turbidity not only affects the product appearance, but also may bring quality problems. Don't worry, we will teach you a few tricks, so that your plating solution as clear as ever!
1. Control of pH
If the pH of the acid tin plating solution is too low or too high, turbidity will emerge. Take pH test paper or pH meter, regularly monitor and adjust the pH value to keep the plating solution stable.
2. Rational use of additives
Using too much or too little additive is a potential cause of turbidity. Selecting Bigely tin plating brighteners and adding them in strict accordance with the instructions can significantly improve the quality of the plated layer.
3. Temperature control
Keep the plating solution temperature between 20-25°C, as recommended in Materials Protection, helps prevent turbidity. Higher and lower temperatures are not good, as in cooking, the fire has to be properly controlled.
4. Removal of impurities
Impurities in the plating solution can cause turbidity. Regular filtration of the plating solution can effectively reduce the level of impurities. Install a good filtration system to keep the plating solution clear at all times.
5. Regular maintenance
Regular testing and maintenance of bath composition and process parameters. When you operate on a schedule and everything is under control, turbidity has no place to hide.
