[Joint Research] Joint research on the effects of morphological changes on washability! Detailed explanations and images are presented.
The no-clean solder paste, which continues to evolve, generates significant heat in fields such as 5G devices and high-power devices for electric vehicles (EVs). As environmental burdens increase, it is necessary to pay attention to long-term changes even in stabilized flux residues. Recent market trends have led to the miniaturization of high-performance electronic devices, resulting in reduced distances between components. This, along with the demand for high-speed calculations and increased capacity, has resulted in high currents and voltages. Consequently, even slight flux residues that were previously not problematic can pose various risks, making cleaning necessary in high-reliability devices, even for no-clean flux residues. Together with Mr. Hiroki, who is developing high-performance solder paste, we conducted joint research on the morphological changes of flux residues after soldering and their impact on cleanability. *For more details, please refer to the related links. *The PDF document is a technical material explaining the evolution and challenges of power devices.

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.
