| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | International Electrotechnical Commission (IEC) prescribes an immunity test (IEC61000-4-2) of electronic equipment for electrostatic discharges (ESDs), and specified the waveform of a discharge current from human ESD, which shall be calibrated for contact discharges of an ESD-gun onto an IEC recommended calibration target with a transfer impedance of 1. For the specified current waveform, however, it cannot always be injected onto actual equipment under test (EUT). In the present study, we investigated to what extent discharge currents injected onto EUT differ from the calibration target current with respect to the metallic size of EUT enclosure. We first confirmed that measured discharge currents for contact discharges of an ESD-gun onto the calibration target can be calculated from the magnetic near field simultaneously measured with a magnetic field probe placed closed to the ESD-gun, and thereby estimated the discharge currents for contact discharges onto a ground plane (1.5m by 1.5m) and circular metal plates with different diameters: 80mm, 50mm and 30mm in lieu of EUT metallic enclosures, and a metal ring (inner diameter: 44mm and outer diameter: 52mm) on the top cover of a battery-driven laptop computer (B5 size) as actual EUT. As a result, we found that the estimated discharge current onto the ground agrees with the target current, and the discharge currents onto the circular metal plates have waveforms with the same rising parts but smaller peaks, which increase with the metal size, reaching 85% and 97% for 30mm and 80mm diameters, respectively. For the laptop computer, it was found, on the other hand, that the discharge current onto a metal ring of the top cover despite small metal size for contact discharges approximately agrees with the target current. | |
