EMI Shielding Spray Coating - Spray Coating

If you are looking for solutions or alternative suppliers for EMI component shielding, whether it is new or existing parts, please consider CHEERSONIC’s spray equipment.

In almost every industry, effective shielding of components from electromagnetic interference (EMI) is essential. All electronic equipment must be protected from any radiation that may interfere with its normal operation.

The ideal shielding layer can isolate the components in seamless spheres made only of highly conductive metals such as aluminum, copper, silver or gold. Of course, this would be completely impractical, let alone the price.

In fact, component housings are usually injection-molded to provide lightweight and inexpensive parts. The part can be easily made into any shape required. However, plastic has no shielding properties. EMI can pass directly.

Therefore, a conductive coating that can increase the shielding performance of the housing or the component itself has been developed. These coatings are used for the first time in aerospace, military and high-tech applications to reflect harmful EMI.

Shielding can be applied to the enclosure to prevent EMI radiation, or it can be directly used on precision electronic components to protect them from interference.

Why use our ultrasonic spraying machine?

Ultrasonic spraying can make the shielding material evenly deposited on the parts, covering every part and contour, even tiny gaps. The spraying process ensures absolute application consistency, which helps to improve quality, cost and material performance. Once the spraying process is completed, it can be fully expanded to meet production needs.

The conductive paint used in spraying contains pure copper and a combination of stainless steel, chromium and other metals to prevent or reduce the effects of EMI. Pretreatment can make the surface to be coated have excellent adhesion, so that a uniform thickness of the coating can be formed without peeling or peeling.
