We check your entire cleaning process using a wide variety of - optical, chemical or physical - test methods.
In addition, we provide you with comprehensive technical reports, including picture evidence, to ensure total transparency and traceability. And last but not least, we assess the possible consequences of residual contamination for you and recommend the appropriate optimisation measures.
PURITY ANALYSIS FROM A SINGLE SOURCEWe Analyse Exactly to the μm for You
The functional reliability of electronic assemblies can be significantly impaired by impurities from the production process, e.g. flux or particles.
Using various analytical methods, we help you to prove the surface purity of your assemblies. However, our analytics go far beyond simply measuring and recording data. Our experienced experts also interpret the results for you and derive the right measures to solve existing problems or optimise your process.
Therefore zestronYour Advantages at a Glance
Proof of surface cleanliness/quality for internal and external ISO audits
Security for warranty claims from customers and suppliers
Verifiable cleanliness for statistical process control
Assurance of the coatability and bondability of your assemblies
Other available methods include, for example, the characterisation of organic residues on surfaces by means of FTIR spectroscopy, particle extraction and analysis according to VDA19 / ISO 16232 to ensure technical cleanliness, visual inspection by means of optical and digital microscopes as well as qualitative thermal analysis for the determination of anions, cations and weak organic acids.
zestron analytikumThe Following Methods are Available for Purity Analysis
ZESTRON reliably ensures a consistently high bath quality of the cleaning process and thus optimal process reliability: Based on the bath samples you send us, we define individual monitoring parameters for you using standardised analysis procedures. This allows you to utilise the maximum bath life of the cleaner and thus reduce your process costs at the same time.
