Supports the maintenance of high purity in semiconductor manufacturing.
In the semiconductor industry, the contamination of minute impurities during the manufacturing process can have a serious impact on product quality and performance. Particularly in environments that require high purity, the leaching of trace components from gaskets and compatibility with fluids become critical issues. Proper gasket selection is essential for improving product yield and reducing manufacturing costs. Our "Gasket Fluid Compatibility Chart" evaluates the compatibility of gaskets with various fluids used in the semiconductor manufacturing process on a three-tier scale of ◎, A, and X, designed for intuitive judgment. This enables the rapid selection of optimal gaskets and helps maintain a high-purity environment. [Usage Scenarios] - Piping in clean rooms - Chemical supply lines - Ultrapure water production equipment [Benefits of Implementation] - Reduced risk of foreign matter contamination - Improved product quality - Stabilization of the manufacturing process
