Maintaining a pristine cleanroom necessitates rigorous control of electrostatic discharge (ESD). ESD, caused from generation of static charge, can severely harm sensitive devices used in electronics manufacturing. Appropriate ESD mitigation strategies require grounding every apparatus, utilizing static-dissipative items like surfaces, attire, and tooling, and implementing moisture regulation to reduce potential build-up. Moreover, personnel education on proper ESD handling is completely essential for maintaining cleanroom purity.
