The unique advantages of PI gold-plated film in electronic products

In the rapidly developing field of electronic technology today, the selection of materials is crucial for the performance, reliability, and stability of electronic products.Polyimide (PI) gold plating filmAs a high-performance composite material that combines high conductivity, excellent shielding effectiveness, and good heat resistance, it is gradually becoming one of the indispensable materials in electronic products. This article will explore the unique advantages of PI gold plating film in electronic products and support its excellent performance through data.

1、 Excellent conductivity performance

The PI gold plating film significantly enhances the conductivity of the PI film through the gold plating process, making it an ideal choice for connecting devices in electronic products. The gold plating layer, as a precious metal coating, has extremely high conductivity and good corrosion resistance. Coating a layer of gold on the surface of PI material can not only significantly improve its conductivity, but also effectively prevent its performance from deteriorating in harsh environments such as humidity and corrosion. For example, flexible circuit boards using PI gold-plated film have significantly improved conductivity, ensuring smooth transmission of electronic signals.

2、 Excellent electromagnetic shielding performance

PI gold-plated film also demonstrates its unique advantages in the field of electromagnetic shielding. Electromagnetic shielding effectiveness (SE) is a key indicator for measuring a material's ability to attenuate electromagnetic waves. occupyAdvanced Institute (Shenzhen) Technology Co., LtdResearch has shown that the SE value of PI gold-plated film in the high frequency range (such as 10MHz to 3GHz) is over 70dB, significantly better than the average SE value of traditional copper plates (about 50dB). This characteristic is particularly important in electronic products with complex electromagnetic environments, such as mobile phones, computers, etc. PI gold plating film can effectively block external electromagnetic wave interference, protect electronic components from electromagnetic radiation, and improve the electromagnetic compatibility of electronic products.

3、 Excellent high temperature resistance

PI material itself has excellent thermal stability and can maintain stable performance in high temperature environments. The PI gold-plated film inherits this characteristic and can maintain stable conductivity and shielding effectiveness in high temperature environments. Experimental data shows that under high temperature (≥ 350 ℃) conditions, the conductivity and shielding effectiveness of PI gold plating film remain stable, far superior to traditional metal shielding materials. This makes PI gold plating film significantly advantageous in the manufacturing of precision electronic components that require high temperature resistance.

4、 Good chemical stability and mechanical strength

PI gold-plated filmHas good tolerance to various chemicals and is not easily corroded or deteriorated. At the same time, it has high mechanical strength, can withstand certain external forces and pressures, and is not easily damaged or deformed. This helps ensure the reliability and stability of precision electronic components.

5、 Widely applicable fields

PI gold-plated film has been widely used in multiple high-tech fields due to its unique performance advantages. In electronic devices, PI gold plating film is commonly used for key components such as flexible circuit boards and touch screens, improving product performance and reliability. In the aerospace field, PI gold-plated film is used for thermal insulation of spacecraft, insulation protection of electronic components, and electromagnetic interference shielding, providing strong guarantees for the safe operation of spacecraft. In addition, PI gold plating film is widely used in military, medical and other fields, providing reliable electromagnetic shielding protection for electronic devices in these fields.

6、 Advanced preparation technology

The preparation of PI gold plating film cannot be separated from advanced metal coating technology. The application of modern coating technologies such as Physical Vapor Deposition (PVD) enables metal materials to be uniformly and densely deposited on the surface of PI thin films, forming a strong and smooth thin layer of metal. This coating technology not only improves the performance stability of PI gold plating film, but also reduces production costs, promoting its wide application in various fields.

conclusion

in summary,PI gold-plated filmIn electronic products, it has unique advantages such as excellent conductivity, outstanding electromagnetic shielding performance, excellent high temperature resistance, good chemical stability, and mechanical strength. These advantages make PI gold plating film occupy an important position in electronic product manufacturing and provide strong support for its wide application in various fields. With the continuous advancement of technology and the improvement of preparation techniques, we have reason to believe that PI gold plating film will play a more important role in the future, promoting the continuous improvement of electronic product performance.
