What should I do if the workpiece cannot be deposited with a nickel layer during the production process using medium-phosphorus electroless nickel plating solution?

2022-02-14

    In the production process of using medium-phosphorus electroless nickel plating solution, the workpiece cannot be deposited with a nickel layer, which will seriously affect the production progress. So what should we do in this situation?

     Bigolly Technology made an analysis based on the field experience and the characteristics of the product's medium-phosphorus electroless nickel plating solution Ni-809,The following points should be noted:


    1. The concentration of stabilizer in the medium phosphorus electroless nickel plating solution is too high.At this time, part of the plating solution should be drained, water should be added to the position of the scale line, and then the concentration of the plating solution should be analyzed and the medium phosphorus electroless nickel plating solution should be added to make the concentration of the plating solution within the process range.

    2. The surface of the workpiece is not activated well. The pre-treatment process of the workpiece should be checked in time and improved.

    3. The surface of the workpiece is not catalyzed. Surface catalytic treatment should be done before the workpiece is plated.

    4. The temperature of the electroless nickel plating solution is too low.During production, use a thermometer to measure the temperature of the plating solution regularly to avoid the temperature of the plating solution being too low due to machine failure or human negligence, and control the temperature within the process range.

    5. The pH value of the electroless nickel plating solution is too low.
Use a pH meter to measure the pH value of the plating solution regularly during production. When the pH value is too low, ammonia water should be used to adjust the pH value of the plating solution to the process range.
    Therefore, in the production process of using medium-phosphorus electroless nickel plating solution, if the workpiece cannot be deposited with nickel, we need to pay attention to the above points, which can effectively reduce the occurrence of failures.If you are interested in medium-phosphorus electroless nickel plating solution, please contact Bigolly customer service, you can get free samples and detailed technical information!
