1. The Importance of Dust Control in Cleanrooms
Dust control is a crucial factor in maintaining a sterile environment in cleanrooms where sensitive products and equipment are manufactured. Even ultra-fine particles, invisible to the naked eye, can seriously affect product quality, cause contamination, and compromise the safety of production processes. In the manufacturing of high-precision devices such as semiconductor chips, displays, sensors, and sterile pharmaceuticals, the presence of particles as small as 0.3 μm – 5 μm can result in severe product defects.
Some key reasons why dust control in cleanrooms is essential include:
-
Preventing product and environmental contamination: Dust particles can carry microorganisms and chemical contaminants that settle on product surfaces, equipment, or wafers/silicon, directly impacting performance and output reliability.
-
Maintaining cleanliness to international standards: A Class 100 (ISO 5) cleanroom requires particle density ≤ 3,520 particles/m³ (0.5 μm size) and ≤ 10,200 particles/m³ (0.3 μm size). Therefore, real-time particle density monitoring is necessary to control HVAC, AHU, FFU, and unidirectional airflow systems.
-
Protecting the quality of sensitive products: Products such as pharmaceuticals, microchips, medical devices, and high-tech items must be produced in dust-free environments. A particle control system ensures that these products are not damaged or contaminated by airborne particles.
-
Safeguarding worker health: Airborne dust can cause health issues for workers, especially fine particles that can enter the respiratory tract. Dust control ensures a safe working environment and protects employee health.
