Indication of resin based residues on pcb assemblies

The ZESTRON® Resin Test visually and temporarily identifies the local distribution of resin-based residues on electronic assemblies via a color reaction. Critical resin residues, which cause poor adhesion of conformal coatings and delamination effects can be localized during the production and removed by a cleaning step. Thus the critical resin amount of <40 μg/cm² (258.06 μg/sq in) according to J-STD 001 can be met. This test complements analytical methods such as Ionic Contamination Measurement (detection of inorganic residues) and the ZESTRON® Flux Test (detection of activators/acids).
