[Data] Particle Counter and Large Particles

The ISO cleanliness level is clear! But why is the work surface contaminated? We will answer that.

This document introduces particle counters and large particles. It addresses the question, "Are there no large particles in clean rooms?" as well as the concerns of "not being able to measure" and "is that all?" Additionally, it includes references on gravitational settling, the particle size of contaminants that should be managed (e.g., thin films, laminating, painting processes), and more. It responds to the misconception that particle counters can handle particle sizes from very small to very large. [Contents] ■ Are there no large particles in clean rooms? ■ Not being able to measure, is that all? ■ Reference 1: What about gravitational settling of particles? ■ Reference 2: Particle size of contaminants that should be managed (e.g., thin films, laminating, painting processes) ■ Reference 3: Real-time mode = seeing what is happening right in front of you *For more details, please refer to the PDF document or feel free to contact us.
