Understanding Cleanroom pressure differential Fundamentals in Semiconductor

Pressure differential optimization begins with understanding the physics of airflow control in contamination-sensitive environments. The fundamental principle relies on creating controlled airflow patterns that prevent particle migration from less clean areas toward critical manufacturing zones. This approach utilizes the natural tendency of air to flow from high-pressure regions toward low-pressure areas, effectively creating invisible barriers against contamination ingress.

Why Temperature and Humidity Control is Critical in Cleanrooms

Semiconductor cleanrooms typically implement cascade pressure systems where the most critical Class 1 areas maintain pressures 25-50 Pa above adjacent zones.
