Before the resin encapsulation of semiconductors: What surface design enhances insulation and bonding strength?
A detailed explanation of specific approaches to surface treatment that are key to maximizing the quality of semiconductor resin encapsulation!
Semiconductor devices, which function as the brains of various electronic devices ranging from smartphones, automobiles, to home appliances that are essential in our daily lives, are supported by their high reliability. One of the key technologies that ensure this reliability is "resin encapsulation." The process of covering and solidifying semiconductor chips with resin is indispensable for protecting them from external environments and maintaining stable performance over long periods. However, as products require higher reliability, there are increasing cases where simply solidifying with resin is not sufficient. To fully realize the true performance of resin encapsulation, it is extremely important how well the surfaces of the semiconductor chips and substrates to be encapsulated are prepared, which is referred to as "surface design." *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.
