Evaluation of Cleanliness in Solder Selection | C3 Ion Chromatography Analysis
Obtain evaluation data under unified conditions for overseas and Japan! Cleanliness evaluation in solder selection | Case study of C3 ion chromatography analysis.
This case introduces the acquisition of evaluation data with unified conditions in Japan and overseas, in collaboration with overseas bases, due to the selection of solder to be used for new products, including factor analysis of detected components. In this case, unlike the analysis based on the overall extraction evaluation of the substrate represented by the ROSE Test, a localized analysis was conducted with a limited evaluation area. Additionally, by combining two analytical methods, it became possible to identify the types of ions affecting the degree of ion contamination and corrosive residues, allowing for the identification of areas on the substrate that are of high concern. [Issue] ■ In selecting the solder to be used for new products, the delivery destination requested the implementation of C3/IC analysis. *For more details, please refer to the related links 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.
