The term conformal coating is typically associated with which protective action?

• A. Conformal coating
• B. Encapsulate
• C. Potting compound
• D. Fungus proof coating

Answer: (B)

Conformal coating is a thin protective film applied to an assembled circuit board to guard against environmental hazards. It coats the surface and contours of the board, protecting traces, pads, and components from moisture, dust, chemicals, and humidity while allowing heat to dissapate and enabling possible rework in some cases. This is different from encapsulation, which would completely surround the entire assembly in resin or epoxy, giving bulk protection but making heat dissipation and future servicing harder. Fungus-proof coatings aren’t a standard term for electronic protection.
