Alternative Testing Method applicable to Air Discharge and Contact Discharge via Fixed Gap from ESD Generator in Contact Discharge Mode

Abstract

An alternative testing method applicable to both air discharge and contact discharge is proposed via a fixed gap from an ESD generator in its contact discharge mode under conditions limited to a test voltage of 8 kV. The method can be used not only to provide the air discharge current close to the step response of the ESD generator through a fixed gap from 0.03 mm to 0.5 mm, but also via 1 mm gap to give the contact discharge current that meets IEC calibration requirements.
