Abstract

The invention discloses an automatic electrostatic discharge test system which comprises a six-axis mechanical arm, an electrostatic discharge generator, a pressure sensor and a rotating platform. The electrostatic discharge generator is arranged at the tail end of the six-axis mechanical arm; and the pressure sensor is arranged at the joint of the six-axis mechanical arm and the electrostatic discharge generator so as to detect the pressure applied by the electrostatic discharge generator to the product to be detected. The device can improve the testing efficiency, guarantees the testing quality, and can prevent the to-be-tested product from being broken when the to-be-tested product is in contact with the electrostatic discharge generator.

Description

technical field [0001] The invention relates to the technical field of electrostatic discharge testing, in particular to an automatic electrostatic discharge testing system. Background technique [0002] With the increasing integration of semiconductor ICs and the thinner gate oxide layer, the phenomenon of ESD electrostatic discharge is fatal to electronic products. It may cause damage to the internal electronic circuits of components and affect the use of electronic products. life. Therefore, it is necessary to carry out electrostatic discharge testing to evaluate the anti-interference performance of electrical and electronic products when they are subjected to electrostatic discharge, so as to ensure product reliability. [0003] Electrostatic discharge generator, also known as electrostatic discharge simulator, is an important instrument used in electromagnetic compatibility ESD testing. The electrostatic discharge generator is mainly used to simulate the electrostatic...
