We will introduce the mechanisms of occurrence, confirmation and analysis methods, as well as frequently asked questions regarding the cleaning of metal salts!
The miniaturization and high-density integration of electronic devices have progressed, and in recent years, there has been advancement in multifaceted operations utilizing AI for automatic control and complex communications. In this context, the reliability required of electronic devices has become increasingly important. Among these, one of the causes of trouble that was not previously anticipated is "unintended metal salts." The formation of metal salts during the soldering process is an essential reaction for establishing solder joints, but there are cases where "unintended metal salts," which do not contribute to the joint, occur as side reactions. *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.
