Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide
Maintaining a pristine cleanroom necessitates careful management of electrostatic discharge (ESD). ESD, stemming from accumulation of static potential, can detrimentally affect sensitive parts used in micro-device fabrication. Appropriate ESD mitigation strategies require earthing each apparatus, employing static-dissipative materials like coverings, clothing, and tooling, and requiring atmospheric management to lessen potential generation. Additionally, personnel training on proper ESD techniques is completely essential for maintaining cleanroom quality.
