Conformal Coatings: State of the Industry Versus State of the Art

The results of a major conformal coatings study, the IPC-TR-587 technical report, ‘Conformal Coating Material and Application ‘‘State of the Industry’’ Assessment’ outlines a crucial IPC study of major conformal coating types, application, cure and coating thickness.

How accurate are conventional nominal thickness assessments?

Are they representative? Could immersion testing be a faster, more predictive indicator of performance in harsh environments?

This fascinating study from Electrolube compares six different coatings on witness/SIR test coupons for condensation resistance performance and shows the extensive cross-sectioning after testing and the outcomes for coating thickness and coverage, to understand how physical material properties combine to determine the Coating Protective Index.
