ZESTRON® Flux Test Kit

Indicates carboxylic-based flux activators through a color reaction

The ZESTRON® Flux Test Kit indicates carboxylic-based flux activators through a color reaction.  This qualitative test is an important supplement to the ionic contamination measurement as non-visible residues can be easily detected.  Additionally, this test helps to identify the local distribution of contamination which in turn provides valuable data pertaining to short-term and long-term failures.


  • The distribution of local contamination helps to determine the climatic reliability of electronic assemblies
  • Quick and easy test method. No extensive training required
  • No special test equipment needed
  • No additional floor space requirements
  • Can be used throughout the facility
  • Low cost per tested part
