1. Product Overview
The ZESTRON® Flux Test is a diagnostic kit designed to detect carboxylic-based flux activators on PCB assemblies through a colorimetric reaction. It supplements ionic contamination measurements by revealing non-visible residues, thereby improving the reliability assessment of electronic components. The test is simple, low-cost, and does not require specialized equipment or extensive operator training.
2. Applications
Identification of local contamination caused by carboxylic flux activators on PCB assemblies.
On-site sampling inspections during production.
Assessment of the climatic and operational reliability of electronic assemblies.
Complementary tool to ionic contamination testing for quality control purposes.
Not suitable for detecting halogenated activator residues.
