The differences between pharmaceutical clean rooms and electronic clean rooms
2026/4/9
The pharmaceutical cleanroom focuses on "ensuring the safety and sterility of drugs", with the main control points being microorganisms, particles, and cross-contamination;
The electronic cleanroom focuses on "protecting precision electronic components", with particular emphasis on controlling tiny particles, static electricity and chemical pollutants. There are significant differences in control standards and design requirements between the two.
01 The control core and goals are different
Pharmaceutical cleanroom: The core is microorganisms (bacteria, molds, etc.) and particles. It needs to prevent drug contamination, ensure sterility and stability, and also prevent cross-contamination between different drugs.
Electronic cleanroom: The core is sub-micron / nanometer particles. It needs to avoid particle attachment causing component short circuits and failures, and strictly control static electricity and chemical pollutants (such as volatile organic compounds).
02 The cleanliness standards and classification are different
Pharmaceutical cleanroom: Follows GMP (Good Manufacturing Practice for Pharmaceuticals), commonly using ISO 14644-1 classification (such as ISO 5/7/8 grades), and also needs to meet microbial limit requirements (such as the number of floating bacteria per cubic meter).
Electronic cleanroom: Follows SEMI standards, with ISO 14644-1 as the main level (such as ISO 1-5 grades, especially in chip manufacturing), focusing on particle size (such as 0.1μm, 0.05μm particle counts).
03 The design and operation details are different
Ventilation and airflow: Pharmaceutical cleanrooms commonly use vertical single-direction flow + high-efficiency filtration, emphasizing uniform air change frequency; electronic cleanrooms pay more attention to airflow stability to avoid particle accumulation, and in some scenarios, inert gas protection is required.
Temperature, humidity and static electricity: Pharmaceutical cleanrooms' temperature and humidity meet the requirements of drug production (such as 20-24℃, 45%-65% RH), with low requirements for static electricity; electronic cleanrooms need precise temperature and humidity control (such as 23±2℃, 40%-50% RH), and must be equipped with anti-static flooring and ion wind equipment.
Materials and disinfection: The walls and floors of pharmaceutical cleanrooms need to be resistant to disinfection (such as alcohol, hydrogen peroxide), without particle shedding, and need to set up disinfection rooms and changing buffer rooms; electronic cleanrooms' materials need to be low volatile, anti-static, and the focus is on dust removal rather than disinfection.
