What is conformal coating? Learn about protective coatings for PCBAs: materials, application methods and environmental protection.
What is Conformal Coating?
Conformal coating is a thin protective layer applied to assembled PCBs to protect against moisture, dust, chemicals and temperature extremes.
Conformal coating is a thin, transparent protective layer (25-75 µm) that shields assembled boards from environmental hazards. Common materials include acrylic, polyurethane, silicone, epoxy and parylene.
Process and Application
Application methods range from spraying and dipping to robotic selective coating. Essential for harsh environments in automotive, medical, industrial and outdoor applications.
