Characterisation of electrostatic discharges from insulating surfaces

Davidson, J. L., Williams, T. J., Bailey, A. G. and Hearn, G. L. (2001) Characterisation of electrostatic discharges from insulating surfaces Journal of Electrostatics, 51 & 5

Record type: Article


This paper investigates how the presence of a grounded backing plane influences the electrostatic discharge (ESD) characteristics from a charged polystyrene sheet. High-speed digital sampling techniques are used to capture discharge current waveforms via a specially designed current probe, the resultant scans giving clear indication of how the surface charge distribution contributes to the ESD. Data obtained indicate that the presence of a grounded backing plate close to a charged plastic surface has a significant effect on the resultant discharge from the surface for a given initial surface charge density. The results suggest that the presence of an earthed metal backing plate can mean the difference between an incendiary and a non-incendiary ESD. This has implications for the design of plastic components for use in sensitive flammable atmospheres.
