Higher use safety and higher automation degree are realized, and the time for arranging the device by an operator is saved.

Description

technical field [0001] The invention relates to an electrostatic discharge test device, in particular to an electrostatic discharge immunity test device. Background technique [0002] The electrostatic discharge immunity test is used to test the anti-static interference ability of a single device or system. The test is to test the device under test by simulating the discharge of an operator or object when it touches the device, or the discharge of a person or object to an adjacent object ( equipment under test, referred to as EUT). [0003] According to GB / T 17626.2 (IEC 61000-4-2) "Electromagnetic Compatibility Test and Measurement Technology Electrostatic Discharge Immunity Test" standard, the electrostatic discharge test needs to be carried out by the tester holding an electrostatic gun. During the test, lithium batteries, etc. Sensitive parts under test may explode and catch fire, posing potential safety hazards. Therefore, there are many researches in this field on av...
