In order to evaluate the toughness of automotive ECU's to electrostatic discharge, a conventional method where electrostatic discharge pulse is applied to connector parts on a printed circuit board is commonly used. But quantitative re-designing principles to improve the static electricity tolerance have not been made clear that completely utilizes the test data shown below till now, because propagation mechanism of static electricity on a circuit board is not clear. This paper describes the ESD current measurement technique which detects the near magnetic field generated by ESD currents. The authors developed to measure the ESD currents using the new loop antenna on a circuit board. The ESD current, was generated with the static electricity applied to a model circuit pattern in conformity with IEC and ISO standard and measured using the antenna. Also it was able to visualize how static electricity energy would propagate through the circuit board. The authors concluded that ESD current measurement by near magnetic field using small shielded loop antenna was effective. The authors also confirmed that this measuring method enables quantitative evaluation of the effect of a bypass capacitor attached as an anti-static-electricity measure, as well as visualization, at the time of static electricity discharge, of discharge current propagation on an ECU circuit board.
