There are more and more electrical and electronic devices integrated in vehicle communication and electromagnetic countermeasure systems. These devices interact with each other through electromagnetic field radiation and signal conduction, making electromagnetic compatibility a problem in system design and use. In order to ensure the normal operation of the equipment and the stability and reliability of the system, electromagnetic shielding design is essential. The purpose of electromagnetic shielding is to control the propagation of electromagnetic noise, so that the instruments in the electromagnetic environment will not produce interference while avoiding electromagnetic interference. Usually, materials with better conductivity and magnetic permeability are used to isolate the area to be shielded from the outside open.
Electromagnetic shielding materials belong to a subdivided industry in the field of new materials. At present, the widely used electromagnetic shielding materials mainly include wave-absorbing materials. In the automotive field, it is specifically used in electronic control units, radars, lidars, sensors, and batteries. It has the advantages of high shielding efficiency, light weight, and structured controllability.
Based on the above content, through the application of the wave-absorbing material, and then firmly attaching the back glue of the wave-absorbing material to the surface of the chip, it can effectively solve the problem of electromagnetic interference. Because the wave-absorbing material has high magnetic permeability and good wave-absorbing conversion effect, it is not fragile, has a wide absorption frequency band, good absorption performance, strong weather resistance, anti-aging, easy to bend, easy to process and cut, moisture-resistant, durable High pressure, long-term use and other advantages, so it is an essential shielding material for electromagnetic shielding design.
Product characteristics of absorbing material:
1. Soft and not fragile, light and thin, easy to process and cut, easy to use, and can be installed in a small space.
2. The product needs to be glued or pressed on the metal base plate to achieve a good absorbing effect.
3. The product can correspond to a variety of sizes and shapes.
4. High temperature resistance and good flexibility.
5. Halogen-free and lead-free, meeting the RoHs directive.
