Coating layer test Refill 0.1L Bottle

The reliability of protective PCB assembly coatings, with regard to climate and harmful gas safety, is essentially determined by the uniform application of the coating without interferences or gaps in the protective layer. In particular, common trouble areas such as solder joint edges and pore channels in coating pooling areas, when lacking a proper coating layer, have detrimental effects on the final board assembly. The ZESTRON® Coating Layer Test utilizes a black color reaction as a visual indicator of defects in the protective coating, even in the case of μ-coatings, adding standardized methods for coating thickness measurements with a rapid detection of defects in closed or dense coatings.
