EMI Shielding Ultrasonic Spraying Coating Technology

Description:

EMI shielding ultrasonic spraying technology is a revolutionary technique for shielding within the critical frequency range of 1-500MHz. As is well known, the frequency range of 1-500MHz covers common frequencies of many electronic devices, from daily smartphones to complex industrial control systems. EMI shielding ultrasonic spraying technology precisely deposits conductive materials to form an ultra-thin but efficient shielding layer, achieving seamless coverage and minimizing signal leakage, thereby improving shielding efficiency. This enables electronic components to operate stably and uninterrupted without electromagnetic interference.


Parameters:

Factors:

1. Material selection Conductivity: The conductivity of the chosen coating without delay impacts the protecting effect, and it is normally imperative to pick substances with excessive conductivity. Particle size: The dimension and distribution of conductive particles can have an effect on the uniformity and protective impact of the coating.
2. Spray parameters Spray pressure: Excessive or inadequate spray strain can have an effect on the thickness and uniformity of the coating. Spray speed: The spray velocity need to be appropriate. If it is too fast, it can also reason uneven coating, and if it is too slow, it can also motive fabric waste.
3. Surface treatment Substrate cleanliness: The cleanliness of the substrate floor earlier than spraying can have an effect on the adhesion of the coating. Surface roughness: A tough floor may additionally result in uneven coating and have an effect on protective performance.
4. Environmental conditions Temperature and humidity: The temperature and humidity of the spraying surroundings can have an effect on the drying velocity and adhesion of the coating. Air flow: Air float can have an effect on the atomization impact of the coating all through spraying.
5. Coating thickness Coating thickness: Appropriate coating thickness can ensure good shielding effect; Being too thin may not effectively block electromagnetic interference, while being too thick may lead to other problems.
6. Post processing technology Curing method: The curing method of the coating (such as thermal curing, UV curing) has a significant impact on the final performance. Coating testing: Corresponding shielding effect tests should be conducted to ensure compliance with design requirements.
