300,000-class Cleanroom definitione
Definition
300,000-class purification clean workshop refers to air pollutants within a certain range of space particles, hazardous air, such as the exclusion of bacteria and the indoor temperature, cleanliness, room pressure, air velocity and air distribution, noise vibration and lighting, static control within a range of needs, especially given the design of the room while. That is regardless of how changes in the outside air conditions, and its interior could all have to maintain the cleanliness requirements originally set properties such as temperature, humidity and pressure.
Standard
300,000-class purification clean workshop main role is to control the product (such as silicon chips, etc.) are in contact clean air temperature and humidity to survive and make the product of the environment in a good space, production, manufacture, this space we called 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 air division standards prescribed in the past. That is not the so-called 100% clean with no dirt, but to control in a very small amount of units. Of course, in line with the dust particles of the standard criteria with respect to our common dust is already a little small, but for the optical structure is concerned, even a little bit of dust will have a very large negative impact, so in the production of optical structure on , dust is inevitable requirement.
