Risks of damage to electronics with reference to charged clothing

Abstract

Risks of damage to electronic devices with reference to charged clothing have been identified and quantified. The key parameters to control, in order to minimise the device failures due to electrostatic discharge (ESD), are peak ESD current and charge transfer in a direct discharge and device charging by induction and rubbing. An extensive experimental program was carried out to gain experience on threshold levels of these parameters. Use of ESD protective garments over normal clothes of operators is highly recommended in order to minimise ESD failures of devices. The ESD protective garments must be properly used and designed, otherwise they themselves form an ESD risk to electronics.
