Abstract

The invention relates to a testing device and system for testing electrostatic discharge protection performance of a TVS (Transient Voltage Suppressor) device. The testing device comprises a PCB (Printed Circuit Board) and a plurality of TVS device bonding pads, the TVS device bonding pads are arranged on the wiring of the PCB, and each TVS device bonding pad is used for packaging the corresponding type of TVS device to be tested. According to the invention, by arranging a plurality of TVS device bonding pads, the testing device for testing the electrostatic discharge protection performance of the TVS device can package a plurality of TVS devices, so that the situation that corresponding schematic diagrams need to be modified and PCB Layout files need to be adjusted when TVS devices with a plurality of packaging modes exist is avoided, the PCB Layout files are designed at one time, the electrostatic discharge protection performance of TVS devices with various packaging modes can be detected, the detection efficiency is improved, and the design cost and the material cost are reduced.

Description

technical field [0001] The invention relates to the technical field of electrostatic discharge (Electro-Static discharge, ESD) testing of TVS devices, in particular to a testing device and system for testing the electrostatic discharge protection performance of a transient suppression diode (Transient Voltage Suppressor, TVS) device. Background technique [0002] At present, electronic equipment, especially communication equipment, needs to design TVS devices on interfaces or modules prone to ESD problems to protect related circuits and ensure that related equipment can still work normally in an environment prone to static electricity. [0003] In the related art, firstly, the layout design of the electronic equipment is carried out, and a packaged TVS device is placed in the layout design drawing. Then produce the finished chip according to the layout design drawing. Finally, the ESD test is carried out on the finished chip to detect the electrostatic discharge protection ...
