The application of thousand-level clean room workshop in optical manufacturing, LED product production, lighting, circuit board, lens, lens production, optical instrument production and research and development will all involve the scope of yellow light clean room. The application of thousand-class optical clean room can greatly improve product quality and production efficiency and enhance its own brand influence.
The main function of clean room is to control the cleanliness, temperature and humidity of the atmosphere where products (such as silicon wafers) come into contact, so that products can be manufactured in a good environmental space. We call it clean room. According to international practice, the level of dust-free purification is mainly based on the number of particles with a particle size larger than the dividing standard per cubic meter of air. In other words, the so-called dust-free, not 100% without any dust, but controlled in a very small unit. Of course, the particles that meet the dust standard in this standard are very small compared with our common dust, but even a little dust will have a very big negative impact on the optical structure, so dust-free is an inevitable requirement for the production of optical structure products.
The number of dust particles with a particle size of less than 0.3 micron per cubic meter is controlled below 3500, reaching the A level of international dust-free standards. At present, the dust-free standards applied to chip-level production and processing have higher requirements for dust than A-level, and such high standards are mainly applied to the production of some chips with higher grades. The amount of dust is strictly controlled within 1000 per cubic meter, which is commonly known in the industry as 1K level.
Clean room mainly has the following three states:
Empty clean room: a clean room (facility) that has been built and can be put into use. It has all related services and functions. However, there is no equipment operated by operators in this facility.
Static clean room: a clean room (facility) with complete functions, proper setting and installation, which can be used or being used as set, but there are no operators in the facility.
Dynamic clean room: a clean room in normal use, with perfect service functions, equipment and personnel; If necessary, you can engage in normal work.
The above is "What industries are the clean rooms with thousand-level requirements used in?" If in doubt, please contact Anhui people and Purification.
