With the development of digital technology, electronic products continue to develop towards lightness, thinness and miniaturization. The mounting density of components is increasing, and the operating frequency is getting higher and higher. Therefore, in a complex electromagnetic environment, electromagnetic compatibility issues between electronic components have become increasingly prominent. As a reliable, fast and effective product to solve electromagnetic compatibility, microwave absorbing materials are increasingly used in electronic equipment, and can be practically applied in mobile phones, computers, military equipment and other scenarios. By adjusting the electromagnetic parameters of the absorbing material, it can be flexibly applied to different frequency bands to solve the electromagnetic compatibility problem.
So how to judge the technological content of the performance of the absorbing material? That mainly depends on the thickness and permeability of the product. In the current trend of increasingly thin and light mobile phones, the noise suppression sheet, which is one of the indispensable parts of OLED screen mobile phones, is also bound to be thinner and thinner, and it is necessary to continuously improve the magnetic permeability to suppress the electromagnetic The noise generated. Among the same type of products, the thinnest Japanese product is 20um, and the domestic product can basically reach this level. Improvements in the highest permeability, thickness, etc. have been greatly improved, and the ultra-wideband radar wave absorption protective coating absorbs Excellent wave performance, good physical and weather resistance, high-frequency silica gel absorbing materials have also realized imported replacement.
At present, the electromagnetic noise suppression sheet and silica gel absorbing patch developed and produced have been widely used in communications, radar and other fields. As an emi shielding material, its excellent electromagnetic wave absorption performance has allowed it to successfully enter many well-known domestic electronic technology products. The core supply chain of the enterprise.
