Today, with the continuous development of material surface treatment technology, nickel plating process has a wide range of applications in many fields. When it comes to nickel plating on PEN (polyethylene naphthalate) films, chemical nickel plating and electroplating nickel plating are two common process choices.

PEN nickel plating filmSignificant achievements have been made in research and development, and there has been in-depth research and practice on the application of these two processes on PEN films.
Application of electroless nickel plating on PEN film
Chemical nickel plating is a method of using a reducing agent to reduce nickel ions in a solution and deposit them on the surface of PEN film without external current. Advanced Institute (Shenzhen) Technology Co., Ltd. has found in its research that electroless nickel plating has unique advantages on PEN films. Chemical nickel plating can form a uniform coating on the surface of PEN film, without being limited by the shape and size of the film. Even for PEN films with complex shapes, a nickel layer with consistent thickness can be obtained. The strong adhesion between the electroless nickel plating layer and the PEN film is due to the chemical bonding formed between nickel atoms and surface molecules of the PEN film during the electroless plating process. In some electronic component packaging applications that require high uniformity and adhesion of the coating, the chemical nickel plated PEN nickel film performs well, effectively protecting internal components and improving product stability and reliability.
However, electroless nickel plating also has some drawbacks. The composition of the plating solution for electroless nickel plating is complex, and strict control of parameters such as temperature and pH value of the plating solution is required. Otherwise, it is easy to cause the plating solution to fail, which makes the cost of electroless nickel plating relatively high. The deposition rate of electroless nickel plating is slow and the production efficiency is low. In the face of large-scale production demand, it may not be able to meet the requirements of fast supply.
Application of Nickel Electroplating on PEN Thin Films
Electroplated nickel plating is the process of reducing and depositing nickel ions on the surface of the cathode (PEN film) by applying an external current.
Advanced Institute (Shenzhen) Technology Co., LtdWhen studying the application of nickel electroplating on PEN thin films, it was found that the biggest advantage of nickel electroplating is its fast deposition rate. In a relatively short period of time, a certain thickness of nickel layer can be obtained on the surface of PEN film, which can greatly improve production efficiency and reduce production costs for large-scale industrial production. The process of electroplating nickel is relatively simple and easy to control. By adjusting parameters such as current density and plating solution concentration, the thickness and quality of the nickel layer can be accurately controlled.
However, there are also some shortcomings in the application of nickel electroplating on PEN films. Due to the edge effect during the electroplating process, the coating thickness at the edges and corners of PEN film is often thicker than other parts, resulting in poor coating uniformity. If a uniform coating is to be obtained, additional process steps need to be added, such as using auxiliary anodes or using special fixtures. Electroplated nickel plating requires conductive treatment of PEN film, as PEN film itself is insulating, which increases the complexity and cost of the process.
Comprehensive comparison between the two
In practical applications, the choice between chemical nickel plating or electroplating nickel plating on PEN films depends on specific requirements and conditions. If the requirements for uniformity and adhesion of the coating are extremely high, and the sensitivity to cost and production efficiency is relatively low, such as in the manufacturing of high-end electronic devices, electroless nickel plating
PEN nickel plating filmIt may be a better choice. For large-scale production, which focuses more on production efficiency and cost control, and has relatively less stringent requirements for coating uniformity, such as surface treatment of general metal packaging materials, nickel electroplating has more advantages.
Advanced Institute (Shenzhen) Technology Co., Ltd. continuously explores optimization methods for chemical nickel plating and electroplating nickel plating processes in the research of PEN nickel plating film, committed to providing higher quality and more suitable PEN nickel plating film solutions for different industries, and promoting the application and development of PEN nickel plating film in more fields.
