Investigation of the igniting capability of ESD sparks

By investigating the physical characteristics of the ignition processing of electrostatic discharge (ESD) sparks, the igniting capability of the ESD sparks are arrived. According to the conditions for the ESD spark and the figuration, the ESD sparks can be classified into six types: the corona discharge, the brush discharge, the cone discharge, the human physical discharge, the spark discharge and the propagation brush discharge. The space distributions and the duration of ESD spark are the key characteristic to determine the igniting capability of ESD sparks. The igniting energy of the typical type ESD sparks are as follows: equal to and less than 0.025 mJ for the corona discharge, 3 mJ for the brush discharge, 10 mJ for the cone discharge, 30 mJ for the human physical discharge, 1 J for the spark discharge and 10 J for the propagation brush discharge.
