Electromagnetic shielding film is an electromagnetic shielding material mainly used for FPC (flexible printed circuit board) and related components. FPC has a thin thickness, light weight, and can be bent and folded to meet the needs of existing intelligent devices. But now people have a higher experience and performance of intelligent devices, so higher requirements are put forward for the electromagnetic shielding film of FPC core materials, which requires high shielding efficiency, thin thickness, light weight, bending resistance, high peel strength, and low grounding resistance.

With the rapid development of intelligent devices, printed circuit boards, as essential electronic components that connect various functional devices, are facing more performance changes due to the demand for intelligent devices. For example, size, stability, flexibility, high-frequency and high-speed performance. In order to meet the needs of the rapidly developing environment of intelligent devices, it largely depends on the use and processing of membrane materials in circuit boards. How should electromagnetic shielding films be developed?

In intelligent devices, electromagnetic shielding films are mainly used for flexible circuit boards or high-frequency circuit boards, and the requirements for electromagnetic shielding films vary depending on the usage scenarios. With the implementation of 5G communication technology, signal series connection has become a core issue, and the market demand for electromagnetic shielding films is constantly increasing.

Electromagnetic shielding film is the core material for ensuring the normal operation of FPC circuit boards. With the rapid development of electronic information technology, FPC is widely used in intelligent devices such as consumer electronics and automotive electronics. FPC has also rapidly developed and widely applied in these markets, thereby promoting the market growth of electromagnetic shielding films.

In recent years, due to the booming development of consumer electronics, automotive electronics, and 5G industries, the demand for electronic components has surged. As the core component of FPC, the demand for electromagnetic shielding films has gradually increased. Electromagnetic shielding film is a type of shielding material mainly made of metal alloy, which is made of special materials and can effectively suppress electromagnetic interference. It is usually affixed to the surface of FPC products. Due to the market's requirements for the rapid development of FPC at high frequencies, the demand for electromagnetic shielding films is becoming increasingly high.

Today, Lesser mainly introduces a device that can be used for high-precision cutting of electromagnetic shielding films - a femtosecond picosecond laser processing system. This equipment adopts an imported picosecond laser, with high energy control accuracy, small heat affected area, fast speed, high efficiency, high beam quality, high processing accuracy, and stable performance. It is an ideal cutting method for electromagnetic shielding films.

The UV picosecond laser cutting machine is known as the fastest knife. Suitable for cutting electromagnetic film shielding, it can also accurately cut materials such as roll to roll, FPC soft board shape, PCB soft hard combination plate, PCB auxiliary materials, PET film, PI film, PP film, adhesive film, copper foil, explosion-proof film, Sony adhesive, etc.

With the rapid development of intelligent devices and the increasing demand, the market scope of FPC has further expanded, and the market coverage of electromagnetic shielding films has continuously expanded, bringing vigorous development to electromagnetic shielding film laser processing equipment enterprises.
