1μm filtration! Contributing to improved yield in semiconductor manufacturing.

In the semiconductor industry, maintaining processing accuracy is crucial for the stable production of high-quality products. Foreign substances in the coolant can lead to processing defects and degradation of product performance, potentially lowering yield rates. Our coolant precision filtration system keeps the coolant clean with a filtration accuracy of 1μm, stabilizing processing accuracy and contributing to yield improvement. 【Usage Scenarios】 - Grinding, polishing, and cutting processes in semiconductor manufacturing - Stabilization of processing accuracy - Reduction of defect rates 【Effects of Implementation】 - Decrease in processing defects - Reduction of defect rates - Improvement in product quality
