Electrostatic defending device of multiple discharge paths

Abstract

The invention relates to an electrostatic defending device of multiple discharge paths. The electrostatic defending device comprises a conducting wire, a discharge part and a plurality of grounding parts, wherein the conducting wire is used for providing electrostatic current to pass through; the discharge part is coupled to the conducting wire; the grounding parts surround the discharge part, anda discharge path is respectively formed between each grounding part and the discharge part for providing electrostatic discharge; and distances of all discharge paths are equal. When the discharge paths are increased, the success probability of inducing the electrostatic discharge is improved so as to ensure that the electrostatic current is easier to dissipate by a plurality of the discharge paths, and the service life of a discharge point and a grounding point is further improved.

Description

technical field [0001] The invention relates to an electrostatic protection device, in particular to an electrostatic protection device with multiple discharge paths. Background technique [0002] Electro Static Discharge (ESD) is one of the main causes of damage to most electronic components or electronic systems, and this kind of electrostatic damage can cause damage to semiconductor components, thereby affecting the function of integrated circuits and making electronic products useless. Traditionally, devices that discharge static electricity are mostly implemented using the principle of tip discharge. The electronic device adopts the electrostatic protection method of tip discharge. The current leads to the grounding position in the device to prevent electrostatic sensitive components or microcircuits from being damaged by static electricity and failing. [0003] However, in the prior art, the tip discharge is used to induce electrostatic discharge to dissipate the elec...

Problems solved by technology

[0003] However, in the prior art, the method of using tip discharge to induce electrostatic discharge to dissipate the electrostatic current often fails to induce discharge in actual operation.

The reasons can be roughly classified as: (1) Improper configuration of the distance between the tips of the two conductors; (2) Other discharge paths appear: the electrostatic arc usually does not follow a straight line, but is located within a three-dimensional space in front of the conductor tip, within a specific distance, as long as there are other (3) continuous discharge for many times; (4) after the conductor tip is discharged many times, the tip part will be oxidized or carbonized, resulting in the tip becoming round and causing the discharge effect to deteriorate.
