Wave-absorbing material is a noise-reduction magnetic film made of soft magnetic powder and resin in a certain proportion.It has high permeability and soft sides covered with double-sided tape.Just paste it in the right position and it has excellent noise suppression.
PH EMC (electromagnetic compatibility) absorbing wave material is mainly attached to the device and location where produce electronic noise and radiation easily such as IC chip, antenna, power, high-speed signal transmission line connector, camera, battery, touch screen from the set-top box, intelligent mobile phone, tablet computer, UAV, GPS navigation, digital camera, recorder, memory, switching power supply and so on. Used to eliminate the electronic noise and radiation generated by these places, so that the electronic products be able to achieve EMC.
It can also be pasted on the shielding box, to provide test environment with no electromagnetic interference to the electronic test.

Microwave absorber material refers to a class of materials that can absorb electromagnetic energy projected onto its surface, and produce absorption by transforming the material’s consumption into heat energy. Engineering applications, the application of this material in electronic equipment can absorb the leakage of electromagnetic radiation, can achieve the purpose of eliminating electromagnetic interference. In addition to the requirements of microwave absorber materials in a wide band of magnetic waves have a high absorption rate, but also require it to have a light weight, temperature, humidity, corrosion resistance and other properties.
A microwave absorber material is a material that absorbs microwave and electromagnetic energy with less reflection and scattering. Also known as radar absorbing material or radar stealth material. The basic principle of microwave absorber is to convert microwave energy into other forms of motion energy through a certain physical mechanism, and convert it into heat energy through the dissipation of this motion. All forms of lossy motion excited by microwaves can be absorption mechanisms. Common mechanisms include electric induction, magnetic induction, electromagnetic induction, and electromagnetic scattering. Practical microwave absorber materials often have multiple mechanisms at work.
Microwave absorber materials used in notebooks, GPS, set-top boxes can play a role in;
Prevent unnecessary radiation within the machinery: affixed to the internal wall of the machine set to prevent cavity resonance;
Prevent radiation generated from electronic parts, circuits: placed in the middle of the two substrates, affixed to the surface of the IC;
Prevent radiation from the wire: winding wire, stick in the flexible circuit board can filter out coupling noise;
Prevent radiation from the edge of the opening: stick in the perimeter of the opening edge of the metal shell to prevent radiation outside.
Microwave absorber refers to the frequency of 300MHz-300GHz electromagnetic waves, is the radio waves in a limited band of short, that is, the wavelength of 1m (excluding 1m) to 1mm between the electromagnetic waves, is the sub-meter wave, centimeter wave, millimeter wave collectively. Microwave frequency is higher than the general frequency of radio waves, usually also known as “ultra-high frequency electromagnetic waves”. For glass, plastic and porcelain, microwaves almost penetrate and are not absorbed, for water and food, they absorb microwaves and heat themselves up, while for metal objects they reflect microwaves.
Our microwave absorber material adopts electromagnetic resonance and eddy current loss type absorbing mechanism. The loss means that when electromagnetic wave enters the absorbing material, its energy is effectively absorbed by the material and converted into heat or other forms of energy and dissipated.
With the development of digital technology, electronic products are constantly developing towards lightness, thinness and miniaturization, and the installation density of components is getting bigger and bigger, while the operation frequency is getting higher and higher. Therefore, in the complex electromagnetic environment, the problem of electromagnetic compatibility between electronic components is becoming more and more prominent.
As a reliable, fast and effective solution for electromagnetic compatibility, wave-absorbing materials are increasingly used in electronic equipment. By adjusting the electromagnetic parameters of wave absorbing materials, they can be flexibly applied to different frequency bands to solve electromagnetic compatibility problems.
