EMCscreenQ&A

QWhat precautions should I take when attaching EMCscreen to walls, etc.?

AEAttach the MSsheets together so that they do not overlap, and seal the seams with conductive tape (aluminum tape, etc.) that is approximately 3 cm wide.

QHow does it differ from ordinary electromagnetic shielding materials such as aluminum or copper metal films?

AAluminum and copper have an electromagnetic wave shielding performance of over 100 dB, and reflect 99.999% of electromagnetic waves. As a result, the effects of reflection and resonance become greater, causing unexpected electromagnetic interference in surrounding devices.
The EMCscreen is punched to reduce the shielding rate to approximately 99%, uniformly reducing the impact on surrounding equipment and reducing electromagnetic interference.
Errors caused by electromagnetic interference in equipment do not require the electromagnetic waves to be reduced to zero; rather, the level of the electromagnetic waves can be reduced to a level where no errors occur. Therefore, materials with appropriate shielding performance for the purpose, such as EMCscreen or MGnet, are more suitable for EMC countermeasures than materials with too high shielding performance.

QHow durable is EMCscreen?

AEMCscreen has excellent corrosion resistance due to the combination of aluminum foil and glass fiber. Aluminum naturally forms an oxide film to prevent corrosion, and the glass fiber itself is highly corrosion resistant and resistant to chemicals and moisture.

QIs EMCscreen fire resistant?

AEMCscreen is also heat resistant (it has passed the first grade of fire resistance), so it is also used in the soundproofing walls of space rockets.

QWhat does EMC stand for?

AIt is an abbreviation of electromagnetic compatibility. It refers to the state in which the electromagnetic interference waves emitted by electrical and electronic equipment do not affect any other equipment or systems, and the equipment itself continues to function satisfactorily even when it is subjected to electromagnetic interference from other equipment or systems.
