Conformal coatings are a specially formulated material, made of silicon, urethane and acrylic, designed to protect printed circuit boards and related equipment from the environment. This improves and extends the circuit board’s working life and ensures security and reliability of performance. These coatings ‘conform’ to the contours of the circuit board and its components creating a thin (25-50 micron) layer which is both lightweight and flexible. Conformal coatings protect circuitry from hazards such as chemicals (e.g. fuels, coolants etc.), vibration, moisture, salt spray, humidity and high temperature. In an uncoated circuit board, these conditions can cause corrosion, mold growth and power leakage resulting in operational failure.
Conformal coatings provide protection for electronic circuitry in a wide range of products including:
- Programmable highway signs
- Mobile phones
- Washers and dryers
- Microwave ovens
- Security systems
- Engine management systems
- Navigation systems
- Radar control systems
As part of our conformal coating division we offer encapsulation services as well. This is a process which coats the product in a thick protective coating, providing an even greater level of protection for the product.
Examples of our work are below. See more in the Conformal Coating gallery.
