Quality Control
Cleanroom quality assurance is achieved through full - process control in design, construction, equipment, monitoring, and management to ensure the environment meets stringent standards. The core aspects are as follows:
Compliant Design and Construction
Select materials (such as stainless steel and anti - static floors) according to the cleanroom class (e.g., ISO Class 5 - 8). Optimize the airflow layout to eliminate dead zones and minimize dust accumulation.
Control cleanliness throughout the construction process: Workers should wear cleanroom clothing. After completion, perform purging and leak testing. Conduct leak testing on high - efficiency particulate air (HEPA) filters before installation (leakage rate < 0.01%).
Reliable Equipment and Systems
Air - handling equipment is equipped with multi - stage filtration (filtration efficiency ≥ 99.99%). Temperature and humidity control is within ±0.5°C/±2% RH. The air velocity of fan filter units (FFUs) is 0.45m/s ± 20%.
Real - time monitoring: Continuously monitor airborne particles, differential pressure, temperature, and humidity. Automatically alarm and adjust when parameters exceed the standard, and restore normal conditions within 10 minutes.
Standardized Operation and Maintenance
Graded cleaning: Wipe dust daily and disinfect weekly. Use anti - static tools and avoid cotton materials.
Regular maintenance: Replace pre - and medium - efficiency filters based on differential pressure. Replace HEPA filters when the final resistance is at least twice the initial resistance. Conduct third - party testing of 12 indicators annually.
Personnel training: Workers must pass assessments on cleanroom behavior and electrostatic protection. The annual retraining rate should be 100%.
