CLEANLINESS ANALYSIS FROM A SINGLE SOURCE
We analyse the exact μm for you
Impurities from the production process, such as flux or particles, can greatly affect the functional reliability of electronic assemblies.
At our disposal, we employ a range of analytical methods to assist you in verifying the surface purity of your assemblies. On top of that, our team of experienced experts interpret the results from the measurement and data recording for you to address existing issues and optimize your process effectively.
That's why 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
ANALYTICAL METHODSState-of-the-art Analytical Methods for Reliable Results
At ZESTRON, we utilize an extensive range of cutting-edge analytical methods and equipment to ensure the utmost reliability for our valued customers.
We employ not only the ionic contamination measurement using a contaminometer for purity determination but also the ion chromatography option for process validation and risk assessment.
Other analytical techniques includes utilization of the FTIR spectroscopy to characterize organic residues on surfaces, particle extraction and analysis in accordance with VDA19/ISO 16232 standards to ensure technical cleanliness, visual inspections using state-of-the-art optical and digital microscopes and qualitative thermal analysis aids to determining the presence of anions, cations, and weak organic acids.
