The cleanliness standard for a Class 100,000 cleanroom is clearly defined: the number of dust particles with a diameter of 0.5 micrometers or larger per cubic foot of air must not exceed 100,000. Simultaneously, there are precise requirements for temperature, humidity, air pressure, and airflow organization. Temperature is generally controlled between 18 and 26°C, humidity is maintained between 45% and 65%, the workshop maintains positive pressure, and airflow is uniformly distributed to create a stable and suitable production environment.
The building structure and decoration materials are the first line of defense. Walls and ceilings often use color-coated steel sandwich composite panels, which are smooth, easy to clean, fireproof, and airtight; floors mostly use epoxy self-leveling flooring or PVC flooring, which are wear-resistant, slip-resistant, and anti-static. The air purification system is the core; air is filtered through primary, medium, and high-efficiency filters to remove dust and contaminants. Air conditioning units regulate temperature, humidity, and airflow, and ductwork evenly delivers clean air. Strict purification procedures are in place for personnel and materials entering and exiting; personnel must change clothes and undergo air showers, and materials must be processed through cargo showers or pass-through windows to prevent external contamination.
In the electronics industry, it provides a clean environment for semiconductor chip manufacturing and electronic component production, reducing dust damage to products and improving yield rates. In the pharmaceutical field, it ensures cleanliness in drug production and medical device manufacturing, preventing microbial contamination and ensuring medication safety and device quality. In the food industry, it is used for food packaging and processing, preventing foreign matter contamination, inhibiting microbial growth, and extending food shelf life.
With its professionalism and reliability, the Class 100,000 cleanroom has become an indispensable guarantee for quality production in many industries, continuously contributing to the high-quality development of products.
