Research on the Causes and Prevention Techniques of Surface Defects on Nickel Plated Copper Foil

Nickel plated copper foilAs a widely used semiconductor LED、 Key materials in fields such as photovoltaics and displays play a crucial role in the modern electronics industry. However, the surface defects of nickel plated copper foil have always been an important factor affecting product quality and reliability. This article will provide a detailed analysis of the causes of surface defects on nickel plated copper foil and propose effective prevention techniques, with particular reference to the research results and practical experience of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

1、 Causes of Surface Defects on Nickel Plated Copper Foil

1. Defects in the matrix material:
   • Copper foil itself has defects such as holes and cracks, which may be amplified or exposed during the nickel plating process.
   • Copper foil may suffer from scratches, oxidation, and other damages during processing or handling, which can also lead to defects in the nickel plating layer.
2. Electroplating solution issue:
   • The impurity content in the electroplating solution is too high, such as metal ions, organic compounds, etc., which can affect the uniformity and adhesion of the coating.
   • Improper control of pH value, temperature and other parameters of the plating solution may lead to defects such as pinholes and pitting in the coating.
3. Electroplating process parameters:
   • Excessive or insufficient current density can affect the deposition rate and uniformity of the coating.
   • Insufficient or excessive electroplating time may result in insufficient or excessive coating thickness, leading to defects such as peeling and cracking.
4. Electroplating process operation:
   • During the electroplating process, if the stirring is poor, bubbles cannot be effectively expelled, resulting in the formation of pockmarks.
   • Improper pre-treatment before electroplating, such as incomplete removal of oil and oxide layer, may lead to weak bonding between the coating and the substrate, resulting in defects such as peeling.

2、 Preventive techniques for surface defects of nickel plated copper foil

Based on the above causes, combined withAdvanced Institute (Shenzhen) Technology Co., LtdBased on practical experience, the following preventive techniques are proposed:

1. Optimize the matrix material:
   • Choose high-quality copper foil as the base material and avoid using defective copper foil.
   • When processing and handling copper foil, be careful to avoid scratches, oxidation, and other damages.
2. Control the quality of electroplating solution:
   • Regularly check the composition and impurity content of the plating solution to ensure its purity.
   • Strictly control the pH value, temperature and other parameters of the electroplating solution to maintain its stability.
3. Optimize electroplating process parameters:
   • Choose the appropriate current density and plating time based on the material of the copper foil and the properties of the plating solution.
   • Through experimentation and practice, continuously optimize the electroplating process parameters to achieve the best coating effect.
4. Improve the electroplating process operation:
   • Strengthen the stirring and exhaust operations during the electroplating process to ensure that bubbles in the electroplating solution can be promptly expelled.
   • Strictly implement the electroplating pre-treatment process to ensure that the copper foil surface is clean and free of oxide layer.
5. Strengthen quality inspection:
   • During and after the electroplating process, quality inspection of the coating is carried out to promptly detect and address defects.
   • Adopting advanced detection equipment and technology to improve the accuracy and efficiency of detection.
