Coating AOI systems inspect the application of conformal coating on electronic assemblies. Automated cameras examine the coating pattern to help identify missed areas, unwanted coverage and other visible application issues within the system’s capabilities.
The inspection setup must suit the coating material and how it appears under the selected illumination. Where a fluorescent tracer is present, suitable lighting can make coverage easier to assess. Connectors, test points and other keep-out areas need clearly defined inspection criteria because coating in these locations can interfere with later use.
Compare board access, component shadowing and the inspection cycle against your application process. Programming should distinguish intentional uncoated regions from genuine omissions. Coverage inspection should also be considered alongside any required thickness or cure checks, since a visible coating image does not establish every aspect of coating quality.
