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: The aim of this work is the investigation of the transient electromagnetic field radiating by two different commercial generators of electrostatic discharges. Measurements of both magnetic and electric field generated by contact electrostatic discharges have been carried out a few centimeters away from the discharge point. In this paper the current transducer, which is used for the measurement of the discharge current is not mounted on a grounded metal plate, but on an insulating material. With this aberration to the Standard a closer simulation to the electromagnetic field produced by the electrostatic discharge generators on the equipment under test is obtained. This experiment is closer to real conditions of electrostatic discharges, which do not involve a metal plate. It is proved by measurements that each generator produces a different transient electromagnetic field, which has different repercussions on the equipment that is tested. Comparisons of the radiating field between the two generators and useful conclusions for the variation of the electromagnetic field are also presented.Measurement 04/2009; · 1.13 Impact Factor

ABSTRACT: This work aims to investigate the transient magnetic field radiating by two commercial generators of electrostatic discharges. Near field measurements have been conducted, a few centimetres away from the discharge point (Pellegrini target). The Pellegrini target is mounted in the centre of a grounded metal plane, inside an anechoic chamber. The measurements are performed in three different directions in relation to the discharge direction. The experimental data show that each ESD generator produces a different transient magnetic field. Furthermore, additional differences in the magnetic field produced by each generator are noted, depending on the direction of the measurement. Finally, comparisons concerning the magnetic field produced by each generator as well as useful conclusions for the decrease of the magnetic field are presented.Measurement 05/2007; 40(4):428-436. · 1.13 Impact Factor
Conference Proceeding: Measurement of the electric field at the near field radiating by electrostatic discharges[show abstract] [hide abstract]
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.
