The ZESTRON® Resin Test Kit visually helps in identifying the local distribution of resin-based residues on electronic assemblies through a color reaction.  The presence of critical resin residues, which cause poor adhesion of conformal coatings and delamination, needs to be fully removed by a cleaning application.

Advantages:

• Localized detection of resin-based contamination on electronic assemblies
• Quick and easy test method. No extensive training required
• No specific test equipment needed
• No additional floor space requirements
• Can be used throughout the facility
• On-site sampling inspection during production
• Low cost per tested part

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.

Advantages:

• 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

Various factors such as “drag-out,” dilution, flux loading, and evaporation can influence the actual concentration. Therefore, routine measurement of all process related parameters are highly recommended. The ZESTRON® Bath Analyzer 10, ZESTRON® Bath Analyzer 20 and ZESTRON® Bath Analyzer 30 are designed for use with ZESTRON's cleaning agents.

In order to achieve consistent cleaning results, the user has to ensure that the actual concentration of the cleaning agent stays within the recommended application range. Various factors such as “drag-out”, dilution and evaporation can potentially influence the actual concentration. Regular measurements of all process related parameters are therefore highly recommended. The ZESTRON® Bath Analyzers are a simple, easy-to-use method which provides reliable and accurate results for fresh and contaminated cleaning baths.
