Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide
Maintaining a pristine cleanroom necessitates strict regulation of electrostatic phenomena (ESD). ESD, caused from accumulation of static charge, can detrimentally harm sensitive parts used in semiconductor production. Appropriate ESD prevention approaches include grounding each apparatus, utilizing antistatic substances like flooring, attire, and fixtures, and enforcing moisture management to lessen potential accumulation. Moreover, personnel training on proper ESD techniques is completely vital for ensuring cleanroom quality.
