Abstract

The invention discloses an electrostatic discharge test system. The electrostatic discharge test system comprises a longitudinal adjustment device, a transverse adjustment device, a vertical adjustment device and a fixing device for mounting an electrostatic gun; the vertical adjustment device comprises a vertical stepping motor and a vertical synchronous belt mechanism, a vertical slide rail anda vertical slider; a driving pulley is in transmission connection with the motor shaft of the vertical stepping motor; the vertical slider is fixed to the synchronous belt of the vertical synchronousbelt mechanism and is slidably disposed on the vertical slide rail; the fixing device is fixed to the vertical slider; and the vertical adjustment device realizes linear advancement through the vertical synchronous belt mechanism and the vertical slider. With the electrostatic discharge test system of the invention adopted, when the antistatic capability of an electronic product is tested by meansof air discharge, it can be ensured that the electrostatic gun can leave the electrostatic induction area of the electronic product in time during one discharging-power storage period of the electrostatic gun, and therefore, damage to the electronic product caused by the instantaneous continuous secondary discharge of the test point of the electronic product can be avoided, and the test accuracyof the antistatic capability of the electronic product can be improved .

Description

technical field [0001] The invention relates to the field of electrostatic discharge testing in electromagnetic compatibility test technology, in particular to an electrostatic discharge testing system. Background technique [0002] Electromagnetic compatibility refers to the ability of a device or system to work normally in its electromagnetically compatible environment without causing unacceptable electromagnetic disturbance to anything in the environment. It is divided into the characteristics of electrical and electronic equipment emitting electromagnetic disturbance to the outside and the ability of electrical and electronic equipment to resist external interference. The electrostatic test verifies the ability of electrical and electronic equipment to resist external interference; electrostatic discharge is the charge between two objects with different potentials Transfer, the energy generated by this may cause data errors or even permanent physical damage to electrical...
