EMI SHIELDING

Electromagnetic interference (EMI) shielding is used for blocking strong electromagnetic fields that would otherwise interfere with sensitive devices and signals. This interference may degrade the devices or stop them from working entirely.

We deliver conductive coatings that provide excellent shielding performance for electromagnetic interference, in high-volume production. These coatings are ideal for use on electronic enclosures and assemblies which require high-level reliable EMI shielding performance. Besides the addition of these excellent properties, our EMC coatings will always be optimized for your specific requirements.

Emimet

Various types of advanced materials are available to provide perfect shielding performance for electromagnetic interference. Apart from our standard EMC coatings, EmiNit2947 and EmiNit 2479, there is the possibility to use other materials as well for electromagnetic shielding performance.

Due to the substrate materials, and environmental factors in housings and components, there might be a need for a specific type of coating material, which can be determined by the characteristics and traits of the material. Stainless steel or titanium will, for example, be an excellent coating material in corrosive environments.

Besides the standard silver and gold coating for EMI shielding, we can also conduct outstanding EMC coatings by the utilization of materials, such as:
