Abstract :
The human body model (HBM), charged device model (CDM) and field induced model (FIM) have been developed to simulate the electrostatic discharge (ESD) event. The charge/discharge processes for these models are analyzed using Maxwell´s technique and a sphere model. Body potentials, energies and the charge transfer during a discharge are calculated as functions of the charge on the source conductor and the capacitance coefficients for the conductors used. Approximate solutions for the HBM are proposed, and measurements made using a system of conductors and a ground plane are used to determine the accuracy of these solutions. Discrepancies between experimental and theoretical results are analyzed using system potential sensitivity factors
