AI Technical Summary
Existing technologies cannot quickly, non-destructively, and quantitatively detect the integrity of silane electrophoretic films on automotive panels, resulting in long testing cycles, high costs, and delayed results, which cannot meet the needs of new product development and production line release.
We employ low-vacuum SEM morphology quantification and four-probe conductivity spatial mapping technology, combined with AI to automatically extract morphological features and conductivity data, to establish a spatial mapping relationship between SEM and conductivity. We then determine the integrity of the film layer by analyzing the defect cluster density and conductivity gradient.
It enables rapid and non-destructive membrane integrity testing, reducing the testing time for a single sample to 1 hour, lowering costs, accurately diagnosing micropores and cracks, reducing defect rates, supporting full inspection on the production line, and outputting the integrity index in real time.
