Company information
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.
