1. Level 1: the dust-free workshop of grade 1 is suitable for the electronic and optical industry of manufacturing integrated circuit chips, and the regulation of integrated circuit chips is sub μ M.
2. Grade 10: the dust-free workshop of Grade 10 is suitable for industrial production of semiconductor materials with network bandwidth less than 2 μ M.
3. Class 100: a class 100 dust-free workshop is not a sterile workshop. It is strict with the natural environment of "sterility test" or "clean" environment. Class 100 clean room can be used for aseptic testing, manufacturing and processing technology of medical and pharmaceutical industry. Many of these clean workshops are used in the production and manufacturing of plant-based objects, surgery, transplantation, and integrated device manufacturing Bacterial infection is more sensitive to the patient's protective treatment, such as bone marrow transplant patients after surgery.
4. Class 1000: the ten thousand level dust-free workshop is suitable for the production and manufacture of high-quality electronic and optical products, as well as for testing, assembly lines, airport snails, high-quality miniature bearings, etc.
5. Class 10000: the 1000 level dust-free workshop is used for the assembly line of hydraulic machinery or standard air pressure machinery and equipment. In some cases, it is also used in the food industry. In addition, the 1000 level dust-free workshop is also common in the medical industry.
6. Class 100000: the class 100000 dust-free workshop is used in many industrial sectors, such as the production and manufacturing of electronic optical products, the production and manufacture of small electronic devices, the production and manufacturing of large and medium-sized electronic technology, the production and manufacturing of hydraulic press or standard pneumatic system software, the production and manufacturing of food industry, and the production of medical and pharmaceutical industries.
7. 300000 level: the 300000 level dust-free workshop is lower, which is used for general cleaning area, such as the corridor with too low level.
