An insulating protective coating applied to the completed board assembly, which conforms to the configuration of the objects coated and provides a barrier against deleterious effects of their environment.
A protective material applied in a thin, uniform layer to all surfaces of a printed wiring assembly including components.
An insulating protective coating which conforms to the configuration of the object coated and is applied on the completed board assembly.
A thin dielectric coating applied to the circuitry and components of printed wiring assemblies for environmental protection against moisture as well as fingerprints. Also provides mechanical protection.
An insulating protective covering that conforms to the configuration of the objects coated (typically printed circuit boards, printed board assembly) providing a barrier against environmental conditions.
Sprayed or dipped. A thin layer of material applied to electronic products to protect it from moisture or other damaging environments.
thin, nonconductive film applied to a circuit for environmental or mechanical protection; usually plastic or inorganic. [SEMATECH
An insulating layer often applied by spraying or dipping that covers and protects the components on a circuit board.
A thin electrically nonconductive protective coating that conforms to the configuration of the covered assembly to provide environmental and mechanical protection.
Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that if uncoated (non-protected) could result in a complete failure of the electronic system. Precision analog circuitry may suffer degraded accuracy if insulating surfaces become contaminated with ionic substances such as fingerprint residues, which can become weakly conductive in the presence of moisture. (The classic symptom of micro-contamination on an analog circuit board is sudden changes in performance at high humidity, for example when a technician breathes on it.)
