A clean room is also called a clean workshop, a clean room, or a clean room. It refers to the removal of pollutants such as particles, harmful air, bacteria, etc. , Indoor pressure, airflow speed and airflow distribution, noise vibration and lighting, static electricity are controlled within a certain demand range, and a specially designed room is given. That is to say, no matter how the external air conditions change, the interior can maintain the characteristics of cleanliness, temperature, humidity and pressure that were originally set.

Clean room, also known as clean room, clean room, clean room or clean room. The main function of a clean room is indoor pollution control. Without a clean room, it is impossible to mass-produce pollution-sensitive parts. In FED-STD-2, a cleanroom is defined as a room with air filtration, distribution, optimization, construction materials and devices, in which specific regular operating procedures are used to control the concentration of airborne particulates to achieve an appropriate level of particulate cleanliness .

The cleanliness of the clean room and the continuous stability of pollution control are the core standards for testing the quality of the clean room. The standard is divided into several grades according to factors such as the regional environment and degree of purification. Commonly used are international standards and domestic regional industry standards. Some well-known In addition to the general standards, the purification engineering company also has its own purification indicators that are higher than the international general standards, and its purification capacity and environmental adaptability far exceed those of international brands. Generally, industrial aluminum (stainless steel square pass, plastic-sprayed square pass) is used as the frame, and the fan filter unit FFU is used to supply air. Anti-static vertical curtains are used around it. Up to 100-100,000 grades; especially suitable for areas in the workshop that require high cleanliness, such as the high-precision product assembly area in the assembly line operation area.

The main function of the dust-free workshop is to control the cleanliness and temperature and humidity of the atmosphere that the products (such as silicon chips, etc.) come into contact with, so that the products can be produced and manufactured in a good environmental space. This space is called dust-free. workshop.

Dust-free paper must be used in clean and dust-free workshops.
