ABSTRACT:
Current injection electrostatic discharge equipment that includes a discharge capacitor connected to the input terminal of a switch or relay which selectively applies a current discharge from the capacitor to a test tip, the wave shape of the current discharge being shaped to match a standardized waveform. Shaping is achieved by providing first and second inductor coils in series between the output terminal of the switch and the test tip, and by providing an electrically conductive plate connected to the junction of the inductors so as to provide a free space capacitance.
