Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide

Wiki Article

Maintaining the pristine area necessitates rigorous control of electrostatic discharge (ESD). ESD, stemming from generation of static potential, can severely harm sensitive devices used in electronics production. Effective ESD prevention approaches include earthing all machinery, using static-dissipative items like flooring, garments, and tooling, and requiring humidity regulation to reduce charge build-up. Further, personnel instruction on proper ESD handling is necessarily essential for guaranteeing cleanroom integrity.
