Detailed explanation of the development trend of conductive shielding film in one article

Driven by the development trends of electronic products such as lightweighting, miniaturization, lightweighting, high-frequency, and high-speed, FPC hasElectromagnetic shielding filmThe functional requirements are also beyond the original higher electromagnetic shielding efficiency. It also needs to be able to effectively reduce the transmission loss of signals. Therefore, in the field of electromagnetic shielding films, high shielding efficiency and low insertion loss have become the development trend of new electromagnetic shielding films.

As an important raw material for flexible circuit boards, it has broad application space in the fields of electromagnetic shielding and absorption. PCB is a key electronic interconnect device for electronic products, known as the "mother of electronic products". Flexible circuit board is a type of printed circuit board that has the characteristics of high wiring density, light weight, bending, and three-dimensional assembly, and is suitable for miniaturized and lightweight electronic products.

The sieve made by special technology is synthesized at high temperature; By special processing, electromagnetic interference is reduced, and shielding glass does not produce distortion in observed patterns (including dynamic color images), with high fidelity and high definition characteristics; At the same time, it also has the characteristics of explosion-proof glass. Effectively blocking the propagation of electromagnetic waves such as radio waves and infrared radiation, thereby successfully blocking the effects of information leakage, electronic eavesdropping, and electromagnetic radiation interference, ensuring the normal operation of equipment, and avoiding the impact of electromagnetic radiation on personnel.

How to make windows have normal lighting and electromagnetic shielding effects. This requires the use of high-tech transparent films that can provide electromagnetic shielding while ensuring high transparency. Electromagnetic shielding film is a transparent film that meets the requirements of light transmission. When the propagation path of electromagnetic waves encountersElectromagnetic shielding filmAt this time, it will change the propagation direction of electromagnetic waves.

When electromagnetic waves couple or radiate from one side to the other, the shielding film can suppress or attenuate the electromagnetic waves. Laptop computers GPS、ADSL、 Mobile phones and other 3C products may produce noise due to high-frequency electromagnetic interference, which affects communication quality
