Which term is a coating type distinct from encapsulation?

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

Answer: (A)

Conformal coating is a thin protective film applied to assembled boards to guard against moisture, dust, and chemicals. It’s the coating type that stays on the surface without fully sealing or enclosing the components. That makes it distinct from encapsulation or potting, which involve surrounding the components in resin or filler to create a full enclosure. Encapsulation and potting completely enclose the parts, offering different protection but making inspection, repair, or rework much harder. Fungus proof coating is also a coating, but in the standard terminology used for electronics protection, the clear category that stands apart from encapsulation is the conformal coating.
