WHAT IS A CONFORMAL COATING?
A conformal coating is a thin polymeric film that conforms to a printed circuit board's contours to protect its components. Conformal coatings protect electronic components from exposure to environmental factors. Examples of these factors include moisture, dust, chemicals, and temperature extremes.
HOW IS IT APPLIED?
Coatings can be applied in many ways, including brushing, spraying, dispensing, and dip coating.
WHAT ARE THE TYPES OF CONFORMAL COATINGS?
Several materials can use conformal coatings, such as acrylics, silicones, urethanes, UV curable, synthetic rubber, and water-based. Each has its characteristics, making them preferred for specific environments and manufacturing scenarios. It is important to choose a coating chemistry meeting the application needs.
