Electrostatic Discharge Immunity

1. Introduction to the test

　　The electrostatic discharge immunity test mainly checks the discharge (direct discharge) caused by people or objects touching the equipment, and the impact on the operation of the equipment caused by the discharge (indirect discharge) of people or objects on adjacent objects of the equipment. During electrostatic discharge, a discharge current of 1-50A can be generated within 0.5-20ns. Although the current is large, the energy is small because the duration is very short. Therefore, general electrostatic discharge will not cause harm to people, but it may cause destructive harm to electronic products such as integrated circuit chips.

　　The test levels of electrostatic discharge test are: contact discharge 2kV, 4kV, 6kV, 8kV; air discharge: 2kV, 4kV, 8kV, 15kV.
