The absence of faults and the closed nature of the protective coating on electronic assemblies have a significant impact on their reliability in terms of climate and harmful gas safety. In particular, edge alignment on connection contacts and pore channels in coating pooling areas should be detected and eliminated quickly, as they can lead to assembly failures.
Zestron's Coating Layer Test makes unclosed layers visible by coloring them black. This rapid test can be used for random samples during production. In addition to detecting defects in the protective coating of assemblies, the coating layer test also functions as a solderability test for components.
