Protect your printed circuit boards from exposure to harsh environments and extend the life of your boards. See if conformal coating is right for you.
Increase reliability in harsh environments
Contamination from moisture, dust, fungus, extreme temperatures, chemicals, and other environmental hazards can impact the performance of your PCBs. If your boards are exposed to these conditions, safeguard them with conformal coating.
What is conformal coating?
Conformal coating is a transparent thin polymeric film that conforms to the contours of your printed circuit board to protect the board’s components with minimal effect on your component weight. Conformal coating is used to protect the surface of the PCB from harsh elements.
Why Use Conformal Coating?
Conformal coating extends the life of your PCB in harsh environments while protecting it from abrasion and moisture. It is ideal when you want to:
- Protect your PCBs from environmental contamination including
- Extreme temperatures
- Other environmental hazards
- Prevent bleed between close components
- Allow closer conductor spacing
- Minimize environmental stress on your PCB
What types and methods do we use?
MacroFab masks and then sprays your PCBs with the conformal coating. Here are the types we provide:
To ensure quality, we add a UV tracer to all of our conformal coating and inspect your boards for quality control under a UV light according to certified industry standards.
MacroFab’s headquarters use a spray coating method which is the second most widely used and accepted application. Advantages of spray coating are the ability to coat at high volumes quickly, reduced masking, better coverage and a more uniform thickness.
We have a Partner Network of more than 40 factories, each with a specific set of capabilities, including various conformal coating types and methods. If you have specific requirements, our experienced team will match your project with a factory equipped for your needs.
