Is the cleaning effect proven? - Challenges in cleanliness evaluation - [Document]
An era where post-cleaning evaluation is questioned! Publication of effective analytical methods other than visual inspection.
This document explains the evaluation methods for cleanliness after flux cleaning. As for existing mainstream evaluation methods, after passing reliability assessments, actual manufacturing processes determine product defects through appearance inspections using AOI. However, there is a growing trend of defects occurring after product inspections. We introduce the factors contributing to such occurrences and effective analytical methods other than appearance inspections, so please take a moment to read through it. [Contents] ■ An era where post-cleaning evaluation is questioned, just like cleaning technology ■ Diversification of flux residue components ■ Separation and analysis methods for complex components ■ Future prospects and added value of cleaning *For more details, please refer to the PDF document or feel free to contact us.

Zestron is a global standard "flux cleaning agent manufacturer" based in Germany, with eight locations worldwide. Our cleaning agents are primarily environmentally friendly water-based cleaners that achieve a balance between cleaning performance and safety, while also enabling the reduction of organic solvents, VOCs, and overall usage to lower costs. At our technical center in Kanagawa, customers can choose from inline and batch-type spray cleaning equipment, as well as jet and ultrasonic devices, tailored to their needs, allowing them to test work cleaning under conditions equivalent to those in production environments. In parallel with the cleaning tests, we analyze cleanliness at our analysis center. Utilizing digital microscopes, FT-IR, ion chromatography, and SEM-EDX/EDS, we can detect flux residues that are often overlooked by visual inspection. After the tests are completed, our engineers will provide a technical report detailing recommended processes. *We generally offer support for cleaning process issues free of charge. If you have any requests or challenges related to flux cleaning, please feel free to contact us.
