The Unseen Contaminant: Taking Charge of Electrostatic Contamination

Electrostatic forces occur naturally in everyday life, in all settings. These invisible fields are typically ignored unless the effects are a nuisance or are destructive. In the cleanroom, however, electrostatic forces contaminate the environment in some ways not normally considered. A practical knowledge and conscious effort must be employed to control and minimize these forces to avoid unexpected, negative cleanroom performance, equipment failures, and product destruction. This course provides students with a thorough, practical understanding and approach to recognizing, measuring, and minimizing harmful electrostatic force contamination in their own cleanrooms.
