1. introduction

With the development of electronic technology, the demand for high-performance electronic materials is also increasing. PET copper foil, as a new type of composite material, has excellent conductivity, corrosion resistance, and mechanical strength, making it one of the important materials in many fields such as electronic devices, communication equipment, solar panels, etc. Therefore, studying the preparation process, physical and chemical properties, and applications of PET copper foil in various fields is of great significance for promoting the development of the entire electronic materials industry.

2. Preparation process of PET copper foil

PET copper foilIt is a composite material composed of polyester film and copper foil, and its preparation process mainly includes the following steps:

(1) Stick the polyester film to the copper foil. The purpose of this step is to firmly bond the two materials together to ensure stability and overall performance in subsequent processing.

(2) Remove excess copper foil through chemical etching, etching and other methods, and finally form PET copper foil with the required thickness and size. The purpose of this step is to adjust the mechanical strength and appearance quality of PET copper foil.

3. Physical and Chemical Properties of PET Copper Foil

PET copper foil has excellent conductivity, corrosion resistance, and mechanical strength, which make it widely used in various fields. Below, we will introduce the physical and chemical properties of PET copper foil from three aspects.

1. PET copper foil has excellent conductivity, with a resistivity only about 1/10 of pure copper. This conductivity makesPET copper foilBecoming an essential part of various electronic devices, communication equipment, solar panels, and other products.

2. PET copper foil has good corrosion resistance and is not easily affected by oxidation, vulcanization, and other factors. This property has made PET copper foil widely used in some fields that require high material corrosion resistance.

3. PET copper foil has high mechanical strength and heat resistance, and can work normally at high temperatures. These properties enable PET copper foil to maintain good performance even in demanding environments.

4. Machinability PET copper foil is a relatively soft material that is easy to bend, cut, and weld during processing. This processability allows PET copper foil to be made into products of various shapes and sizes, meeting the needs of different fields.
   

PET copper foil has a wide range of applications in many fields due to its excellent physical and chemical properties. The following will introduce the application research of PET copper foil in electronic devices, communication equipment, solar panels and other fields.

1. electronic devicePET copper foilAs a conductive material, it is often used to manufacture various electronic devices such as mobile phones, tablets, laptops, etc. Among these electronic products, PET copper foil is mainly used to connect circuit boards and components to achieve current transmission and control. Compared with ordinary copper foil, PET copper foil not only has better conductivity, but also higher mechanical strength, which can ensure the reliability and stability of electronic products.

2. PET copper foil is widely used in the field of communication equipment, such as antennas, microwave impedance matching devices, etc. The main function of PET copper foil is to provide reflection, refraction, and conduction of high-frequency electromagnetic waves. In addition, PET copper foil can also be used to manufacture high-speed signal transmission lines to meet the high-speed and high bandwidth requirements of data transmission.

3. In recent years, solar panels have become a new type of energy product. PET copper foil, as one of the main materials for solar panels, has good conductivity and corrosion resistance. Therefore, in the manufacturing process of solar panels, PET copper foil can be used as electrode sheets and connecting lines to ensure the high efficiency and long lifespan of solar panels.
