Laser equipment for high-precision cutting of electromagnetic shielding films

Electromagnetic shielding film is an electromagnetic shielding material, mainly used for FPC (flexible printed circuit board) and related components. FPC is thin, light, bendable and foldable, meeting the needs of existing smart devices. But now people have a higher experience and performance of smart devices, so they have higher requirements for the electromagnetic shielding film of FPC core materials, which requires high shielding efficiency, thin thickness, light weight, bending resistance, high peeling strength and low grounding resistance.

With the rapid development of smart devices, printed circuit boards, the key components connecting various functional devices, as indispensable electronic components, are facing more performance changes due to the needs of smart devices. For example, size, stability, flexibility, high frequency and high speed performance. In order to meet the needs of the rapid development of smart devices, it depends largely on the use and processing of membrane materials in circuit boards. How should electromagnetic shielding films develop?

In smart devices, electromagnetic shielding film is mainly used for flexible circuit boards or high-frequency circuit boards. Different usage scenarios have different requirements for electromagnetic shielding film. With the realization of 5G communication technology, signal series connection has become a core issue, and the market demand for electromagnetic shielding film has continued to increase.

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

In recent years, due to the vigorous 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 film has gradually increased. Electromagnetic shielding film is a shielding body mainly based on metal alloys, made of special materials, which can effectively suppress electromagnetic interference and is usually attached to the surface of FPC products. Due to the market's requirements for high-frequency and high-speed development of FPC, the requirements for electromagnetic shielding film are getting higher and higher.

Today, Laisai Xiaobian mainly introduces a device that can be used for high-precision cutting of electromagnetic shielding film-femtosecond picosecond laser processing system. The equipment uses imported picosecond lasers 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 film.

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

With the rapid development and increase in demand of smart devices, the market scope of FPC has further expanded, and the market coverage of electromagnetic shielding film has continued to expand, bringing vigorous development to electromagnetic shielding film laser processing equipment companies.
