1. Uneven thickness of plating layer:
Solution: Adjust the current density of the electroplating equipment to ensure that the current is evenly distributed on the entire workpiece surface; Check the formulation of the electrolyte to ensure that its components are homogeneously mixed; Check whether the operation of the plating equipment is correct, such as stirring the electrolyte, adjusting the position of the electrode, etc.
2. Rough plating:
Solution: Check whether there is suspended solids in the electrolyte, filter or replace the electrolyte if necessary; Adjust the current density to ensure even current distribution; Check whether the operation of the electroplating equipment is correct, such as controlling the temperature of the electrolyte, stirring, etc.
3. Blistering of the plating layer:
Solution: Check whether the electrolyte contains too much gas, and if necessary, degassing treatment; Adjust the current density to avoid being too high; Check whether the operation of the electroplating equipment is correct, such as controlling the stirring of the electrolyte, the position of the electrodes, etc.
4. Plating peeling off:
Solution: Check whether the surface treatment of the substrate is sufficient, and if it needs to be retreated; Check the adhesion between the plating layer and the substrate, and re-treat if there is a problem; Check whether the operation of the plating equipment is correct, such as current density, plating time, etc.
5. The color of the plating layer does not meet the requirements:
Solution: Check whether the formula of the electrolyte is correct and adjust it if necessary; Adjust the current density to ensure even current distribution; Check whether the operation of the electroplating equipment is correct, such as controlling the temperature of the electrolyte, stirring, etc.
6. Cracks in the plating layer:
Solution: Check whether the electrolyte contains too many stress-generating substances, and adjust the formula if necessary; Adjust the current density to avoid being too high; Check whether the operation of the electroplating equipment is correct, such as controlling the temperature of the electrolyte, stirring, etc.
7. Dark spots or oxidation of the plating layer:
Solution: Check whether the electrolyte contains impurities, and filter or replace the electrolyte if necessary; Adjust the current density to ensure even current distribution; Check whether the operation of the electroplating equipment is correct, such as controlling the temperature of the electrolyte, stirring, etc.
8. Wrinkles in the plating layer:
Solution: Check whether the current density is uniform and adjust it if necessary; Check whether the operation of the electroplating equipment is correct, such as adjusting the temperature of the electrolyte, stirring, etc.; Check that the substrate surface is flat and rework if necessary.
9. Color difference in the plating layer:
Solution: Check whether the electrolyte contains impurities, and filter or replace the electrolyte if necessary; Adjust the current density to ensure even current distribution; Check whether the operation of the electroplating equipment is correct, such as controlling the temperature of the electrolyte, stirring, etc.
10. Air bubbles appear in the plating layer:
Solution: Check whether the electrolyte contains too much gas, and if necessary, degassing treatment; Adjust the current density to avoid being too high; Check whether the operation of the electroplating equipment is correct, such as controlling the stirring of the electrolyte, the position of the electrodes, etc.
