Clean room, also known as clean rooms or clean rooms. It is the basis for pollution control. Control airborne particle concentration, so as to achieve an appropriate particle cleanliness levels. Refers to the clean room air pollutants within a certain range of spatial microparticles, harmful air, bacteria, etc. excluded, and the indoor temperature, the cleanliness, room pressure, air speed and air distribution, noise and vibration and lighting, static demand control within a certain range, specially designed rooms and given. Clean room regardless of how changes in the external conditions of the air, its interior can have all previously set to maintain the cleanliness requirements of characteristics, temperature, humidity and pressure and other properties of. The main role of the clean room is to control products (such as silicon chips, etc.) in contact with the atmosphere and clean live temperature and humidity, so that products can be in a good environment space of production, manufacture, this space we call clean room. According to international practice, Clean purification level is mainly based on the particle diameter is larger than the number of particles per cubic meter of criteria for the classification of air to regulations. That is called not 100% clean of any dirt, but to control in a very small amount of units. Of course, the particles of dust standards comply with this standard with respect to our common dust is already a little small, but in terms of the optical structure, even a little bit of dust will have a very large negative impact, so the optical construction products , dust is an inevitable requirement. As shown in Table number of dust per cubic meter will be greater than 0.5 micron particle size control in 3500 or less, reached the international standard Class A dust-free. Application of chip-level of clean production and processing standard requirements for dust higher than A-level, such a high standard to be applied in a number of major high level of chip production. Dust quantity is strictly controlled in less than 1000 per cubic meter, which is the industry called 1K level. 1.
