The grade of a clean room is usually divided according to the number and size of particles allowed in the air. Internationally, 14644 grades are usually used for classification. According to this standard, the grades of clean rooms are from high to low: 150-9. It should be noted that clean room standards can vary depending on the specific industry and application. In semiconductor chip production, clean room standards are usually stricter to ensure that the quality and performance of the chips produced meet expectations. The level of clean room can be divided into :1 level > 10 level > 100 level > 1000 level > 10000 level > 100000 level > 300000 level.
Class 1 clean room is mainly used for manufacturing integrated circuits in the microelectronics industry, and the accuracy of integrated circuits is required to be submicron level.
The Class10 clean room is mainly used in the semiconductor industry with a bandwidth of less than 2 microns.
Class 100 cleanliness is widely used to meet the cleanliness needs of most industries. Aseptic production technology for the pharmaceutical industry. The cleanroom can be used for surgery to manufacture grafts and integrators, as well as for isolation treatment of patients who are particularly sensitive to bacterial infections.
Class 1000 clean room is mainly used for the production of precision optical products, but also for testing, aircraft telescope assembly, precision micro-bearing assembly, etc.
Class 10000 clean rooms can be used for the assembly of hydraulic or pneumatic equipment and in some cases also in the food and beverage industry. In addition, class 10000 clean rooms are also widely used in the medical industry.
