Electronics factories typically rely on the ISO 14644-1 standard for cleanroom classification, which ranges from ISO 1 (highest cleanliness) to ISO 9 (basic dust control). The optimal classification depends on production processes and component precision requirements:

• Application Scenarios: Chip manufacturing, wafer processing, advanced packaging, photolithography operations, and high-density PCB assembly
• Particle Control Standards:
•  
  • ISO 5: ≤3,520 particles (≥0.5μm) per cubic meter
  • ISO 4: ≤352 particles (≥0.5μm) per cubic meter
  • ISO 3: ≤35 particles (≥0.5μm) per cubic meter
• 
  
• Special Requirements: Requires laminar airflow systems, strict temperature/humidity control (±0.1°C/±2%), vibration isolation, and molecular contamination (AMC) filtration
