Defect Bulletins
This section contains SCH’s technical bulletins on conformal coating defects. For full guides, return to the Conformal Coating Defects Hub.
Pinholes, Bubbles & Foam
Entrapped air, skinning and viscosity issues leading to bubbles and burst pinholes in the coating film.
Capillary / Wicking Around Components
Unwanted coating creeping under parts due to surface tension, gaps and process speed.
De-Wetting
Coating pulls back from surfaces due to contamination or low surface energy—identification and correction.
Orange Peel
Rough, textured surface caused by poor flow, atomisation issues or solvent imbalance.
Delamination
Coating lifting or separating from surfaces due to poor adhesion, contamination or stress.
Cracking
Film fractures caused by mechanical stress, incorrect cure cycles or excessive coating thickness.
Corrosion & Ionic Contamination
Residual ions and moisture driving leakage/corrosion; prevention and testing.
