Are you overlooking ion residues? An explanation of the pitfalls of flux cleaning.
Organic solvents, which are used in various fields, are currently an indispensable part of the chemical industry, and it is difficult to completely stop their use. In recent years, due to technological advancements and corporate efforts in various industries, the amount of organic solvents used and their atmospheric emissions have been significantly reduced. However, in the flux cleaning of electronic devices in Japan, cleaning agents primarily based on organic solvents are widely used. However, flux cleaning has essentially transformed into "complex residue cleaning," and while solvent-based cleaning agents are very effective against organic components such as rosin, they are almost unable to dissolve ionic substances or insoluble metal salts, making removal by "dissolution" methods difficult. *For more detailed information, please refer to the related links.

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.
