Chemical Resistance Coatings for Circuit Board Protection

Contact Us

Plasma Ruggedized Solutions’ conformal coatings, potting/encapsulation processes offer physical protection of the treated products. But, certain applications can also be used for circuit board protection and security purposes. Our circuit board protection services help prevent reverse engineering, physical tampering, and information and data theft.

Customized Circuit Board Protection

Plasma Ruggedized Solutions can add opaque conformal coatings for circuit board protection to hide writing, legends, and names (manufacturers, etc.) on components. We offer epoxy, urethane, and silicone hard coatings that provide superior physical protection, and are difficult to remove or rework, making physical tampering nearly impossible. These coatings undergo more involved curing processes which use both ambient and thermal cure to develop their hard finishes. The coatings applied for circuit board protection are considerably thicker than coatings used for other purposes. Standard coatings are approximately 3 mil thick—for circuit board protection purposes, it is between 4 and 5 mil, the upper range of possibility for coating thickness.

Circuit board protection and chemical resistance coatings are often used for new products and designs that companies are just developing or releasing, to make copying or reverse engineering of the internal workings far more difficult. Plasma Ruggedized Solutions’ coating services have the added bonus of making the treated products much more physically robust, making it a better overall product with a longer potential operating life. In addition to physical protection, these specialized substances impart chemical resistance coatings qualities as well.

Potting & Encapsulation Services

The most effective coating methods for circuit board protection are potting/encapsulation. Epoxy is most common, but we offer a wide range of materials to meet your project’s requirements. Whether you need something with low or high thermal transmission qualities, opaqueness for visual security, or any other special properties, Plasma Ruggedized Solutions will work with you to create the ideal solution for your needs. We can also assist in the design of special housings, shells, or other casings for your assemblies to add a further level of security.
