Application of absorbing material products

1. It can be used in the cavity of electronic equipment such as notebook computers, mobile phones, communication cabinets, etc.

2. It can be used to reduce the radiation and noise of various electronic equipment.

3. It can reduce the coupling conduction radiation interference between low frequencies and reduce the low frequency echo interference

4. It can reduce the internal EMI (resonance, crosstalk) in the barrier frame.

5. Applied between the chip and the heat dissipation module.



6. Application of EMI/RFI: EMI (Electro Magnetic Interference): literally translated as electromagnetic interference. The three elements of electromagnetic interference: interference source, interference propagation path and sensitive equipment. Interference source refers to the electronic equipment or system that produces electromagnetic interference, interference propagation Ways include cables, space, etc. Sensitive equipment refers to electronic equipment or systems that are susceptible to electromagnetic interference. Radio frequency interference (RF Interference): Radio frequency is a high-frequency alternating current, also known as electromagnetic waves. Radio frequency interference is the interference caused by electromagnetic waves. For example, two electromagnetic waves with similar frequencies will be received by the receiver at the same time and cause interference. There will be harmonic interference near the transmitting station. Interference with other receiving equipment. Transmitting electromagnetic waves of the same frequency can interfere with the radio station.

In a complex electromagnetic environment, how to prevent and eliminate electromagnetic pollution is very necessary. The wave absorbing material is made of rubber, resin, magnetic powder and other materials, and is prepared by a new film forming technology. It has the characteristics of high magnetic permeability and good wave absorbing and shielding effect. It is widely used in the fields of smart consumer electronics and automotive electronics. Above, the use of absorbing materials attached to the surface of electronic components can effectively absorb noise, reduce electromagnetic radiation, and inhibit electromagnetic interference. Take the computer as an example, the absorbing material is attached to the surface of the electronic original (such as LCD module, keyboard, CPU, memory and other components) to effectively reduce the influence of electromagnetic interference on the surrounding devices, thereby ensuring the normal operation of the device. In OLED modules, the application of absorbing materials can prevent flickering.
