Conformal coating is a process in which a transparent material is applied to electronic components and circuitry to guard against elements that could damage the functions of the circuit board, including harsh temperatures, moisture, dust or other factors. Conformal coating is often used instead of potting because it is lighter, easier to test and easier to repair.
The types of coatings available vary greatly and could include: acrylic, silicones, epoxy, polyurethane, parylene and more.
Just as there are many choices for conformal coating materials, there are also a variety of application methods. The coating is chosen specifically for the application of the custom printed circuit board assembly. The application method is chosen based on the material selected. In most high-tech contract electronics manufacturing facilities, application by semi-automated equipment is the preferred method. At SMD, we use a PVA system to best meet our customers’ specific needs.
SMD offers conformal coating as an additional value-added service to our customers. For the past 25 years, we have made every effort to stay ahead of manufacturing trends and technologies to better serve our customers.
