Experimental investigation of indirect electrostatic discharge (ESD) for a three body problem

摘要

An experimental investigation of indirect electrostatic discharge (ESD) events for a three body geometry was conducted. Using conducting cylinders of different sizes to model the test system's conductors, capacitance coefficients were measured and body potentials calculated for different geometries of the three floating conductors in close vicinity. The test geometry was chosen to model the approach of the charged human body to an electronic systems which has a neighboring floating conductor. Parameters studied include body sizes, test geometry, and the relative magnitude and polarity of the charges on the three bodies. The results of this work provide a better understanding of the fundamental principles involved in the ESD event involving three bodies. The results have application in estimating the effect of ESD on electronic devices and systems.
