Clean room is a specially designed environment engineered to exclude airborne particles, bacteria, and other harmful pollutants. It maintains precise control over indoor temperature, cleanliness, interior pressure, air velocity, air distribution, noise, vibration, lighting, and static electricity. Regardless of external air condition fluctuations, the interior space consistently meets original requirements for cleanliness, temperature, humidity, and pressure performance.
The primary function of a clean room is to control environmental cleanliness and atmospheric humidity for products during the manufacturing process (such as silicon semiconductors). By creating an optimized production environment, it ensures product integrity. International standards dictate purification levels based on the concentration of particles per cubic meter. While "dust-free" does not mean zero particles, it refers to strictly controlled, minute levels that prevent negative impacts on highly sensitive optical and electronic structures.
