| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The electromagnetic (EM) noise caused by electrostatic discharge (ESD) events due to charged metals is a major source of malfunction to high-tech equipment. Especially, electronic devices and equipment for vehicles are being used in strict EM environment, and there is a tendency for high-tech equipment to increase also in cars. However, single-sided printed circuit boards (PCBs) are still used for that electronic equipment due to simplified fabrication and low production costs. The PCBs of this kind is said to have some immunity to EM noises so far, while its mechanism has remain unknown. The ESD immunity testing is being specified in the IEC61000-4-2, which prescribes the current waveform from an ESD-gun. In this study, with our previously developed FDTD model of the ESD-gun, we simulated the induced voltage in a signal trace fabricated on a single-sided PCB together with magnetic near-field. As a result, we found that there were some discrepancies between simulated and measured voltages induced in the trace despite good agreement between simulation and measurement of the magnetic near-field when the ESD-gun was placed close to the trace, and that fair agreement was observed in simulated and measured induced voltage waveforms when the ESD-gun was rotated so as to be away from the trace. These findings suggest that the induced voltages may be caused by the injected discharge current and the electric coupling between the trace and the EM valve installed in the ESD-gun, and that the simulation problem in this case is due to lack of FDTD modeling corresponding to the EM valve. | |
