Wafer is the basic material for manufacturing semiconductor chips. After a long crystal growth process, the silicon ingots are cut, barreled, sliced, chamfered, polished, laser engraved and packaged to become the basic raw material of the integrated circuit factory. - Silicon wafers. After so many processes, wafers are not easy to obtain, and wafers are very important in the process of revolving storage. The wafer patch ring can well fix the wafer inside the frame box, so that the wafer can be transported during the production process without causing damage to the expensive wafer and scratching. DongHongXin wafer ring Wafer patch ring material is made of imported materials from Japan. It has the advantages of flatness, high hardness, excellent folding resistance, excellent corrosion resistance and strong scratch resistance. At the same time, the surface is specially treated to keep it clean for a long time. Bright and beautiful!
