Maintaining a pristine cleanroom necessitates careful management of electrostatic discharge (ESD). ESD, resulting from generation of static potential, can detrimentally damage sensitive parts used in electronics manufacturing. Appropriate ESD prevention strategies require earthing every apparatus, employing static-dissipative materials like flooring, attire, and tooling, and implementing moisture regulation to lessen charge build-up. Moreover, personnel training on proper ESD handling is absolutely critical for ensuring cleanroom integrity.
