  • Page 13: Avoiding Electrostatic Discharge Damage

    Getting Started Avoiding Electrostatic Discharge Damage The human body can collect thousands of volts of destructive static electricity from ordinary activities, for example, walking on a rug, handling synthetic materi- als, or wearing synthetic clothes. When this static electricity discharges onto another surface at a different voltage potential, it is called electrostatic discharge or ESD .
