Introduction to EMC Electromagnetic Compatibility Shielding Film
Electromagnetic shielding filmApplied to industries such as 5G communication and automotive electronics. In the 5G environment, the trend of lightweight, short, high-frequency and high-speed electromagnetic shielding film products in consumer electronics, represented by smartphones, is becoming increasingly evident. The use of internal structure FPC is constantly increasing to improve the internal assembly density. At the same time, electromagnetic interference between electronic components is becoming more serious, which objectively increases the demand for electromagnetic shielding film. This demand is reflected on the one hand in the increase of electromagnetic shielding film usage, and on the other hand in the requirements for improving the performance of electromagnetic shielding film (such as thinner thickness, higher shielding effectiveness, lower insertion loss, stronger bending resistance, stronger tear resistance, etc.)
EMC electromagnetic compatibility shielding film is mainly used for installation on the metal shielding shell of circuit boards. It has good electromagnetic shielding performance and can effectively suppress circuit faults and damage caused by electromagnetic wave coupling or radiation. Electromagnetic shielding film is a functional thin film that has a good inhibitory effect on electromagnetic interference. The principle is to embed a layer of metal film inside the metal shell of the circuit board, thus forming a circuit shielding layer that has a shielding effect on electromagnetic waves.
EMC electromagnetic compatibility shielding filmIt is also a material used to prevent electromagnetic wave interference, and its functions are as follows:
1. Shielding electromagnetic waves: EMC electromagnetic compatibility shielding film can reflect or absorb electromagnetic waves through its conductive layer, thereby achieving shielding effect and protecting electronic devices from external electromagnetic interference.
2. Reduce radiation: In some situations where electromagnetic radiation is required, EMC electromagnetic compatibility shielding film can reduce the radiation level and ensure that electromagnetic radiation meets national and international standards.
3. Improve performance: In some demanding electronic devices, installing EMC electromagnetic compatibility shielding film can improve the stability and reliability of the equipment, and reduce the failure rate.
4. Privacy protection: In some high security situations, EMC electromagnetic compatibility shielding film can protect the internal information of the device from external theft.
In summary, EMC electromagnetic compatibility shielding film plays an important role in protecting electronic devices from electromagnetic interference, improving device performance and reliability, and protecting privacy.
