1. Dust-free: dust-free workshop is usually used for the production of very demanding products, such as electronic equipment, optical products and other production environment. Dust free workshop keeps the dust and particulate matter in the air at very low level through fine air filtration system and other control measures to ensure the quality and reliability of the products.
2. Aseptic: Aseptic means that no microorganisms exist in the workshop. In some industries, such as pharmaceuticals and medical devices, the requirements for product sterility are very high. Aseptic workshops use a series of control measures, such as air filtration, disinfection and sterilization, to prevent microbial contamination and ensure product safety and effectiveness.
3. Static-free: Static-free means that the generation and accumulation of static electricity in the workshop is effectively controlled and does not affect product quality and the production process. In some industries, such as electronics, semiconductors, etc., static electricity may have an impact on the product, such as damage to the device, interference with the signal. Static-free workshop controls and eliminates static electricity through measures such as ground conductivity and static eliminators to ensure product quality and reliability.
In summary, the "three noes" of the clean room refers to dust-free, bacteria-free and static-free, and is to ensure the quality and reliability of the product and take strict environmental control measures.
