Fields on the horizontal coupling plane excited by direct ESD and discharges to the vertical coupling plane
ABSTRACT Field levels in indirect electrostatic discharge (ESD) test setups are hardly known yet. It has been proposed to ANSI and IEC to use a horizontal simulator position instead of a vertical position in indirect ESD testing. This paper shows the field values on the horizontal coupling plane for different excitations and grounding topologies and questions if the goal of the change – a reduction of the simulator influence – will be achieved. Also, investigations dealing with the sensitivity of digital devices to impulsive fields are presented.

ABSTRACT: This work aims to study the transient electric field radiating by two different generators of electrostatic discharges, which are constructed according to the Standard related to electrostatic discharges. Measurements of the electric field generated by contact electrostatic discharges a few centimetres away from the discharge point are presented. With the aberration to the Standard that the current transducer is mounted on an insulating material instead of a metal plate a closer simulation to real electrostatic discharges is obtained. Measurements proved that there are differences from generator to generator and also differences at the same generator, depending on its orientation.6th WSEAS Int.

ABSTRACT: The aim of this work is the investigation of the transient electric field radiated by two different commercial generators of electrostatic discharges for various charging voltages. Measurements of the electric field generated by contact electrostatic discharges have been conducted a few centimetres away from the discharge point. In this paper the current transducer, which is used for the measurement of the discharge current, is mounted on a grounded metal plane. It is the first time that measurements of the electric field have been conducted along three different directions in relation to the electrostatic discharge generator. Measurements prove that each generator produces a different transient electric field, which affects the equipment that is tested in a different way. Also, each generator produces a different electric field depending on the orientation of the generator. Finally, comparisons of the electric field for both generators and useful conclusions for the decrease of the electric field are presented.Measurement Science and Technology 06/2006; 17(6):1292-1298. · 1.44 Impact Factor
