Embodiment Construction

[0023] In order to improve the problem that the existing circuit board cannot pass the electrostatic discharge test before leaving the factory, the present invention proposes an electrostatic discharge protection device for the circuit board.

[0024] Among the protection methods of electrostatic discharge, grounding is the most effective and economical method. The charge accumulated on the object will completely release the energy in one discharge, which is the main cause of electrostatic discharge damage. The method of protection is to connect all objects together, then ground, and maintain a low grounding resistance, so that the charge on the object can quickly dissipate to the earth, avoiding the harm of electrostatic discharge.

[0025] Therefore, the present invention utilizes an ESD protection device for a circuit board, and disposes it near the tip portion where ESD is likely to occur, such as screws, I / O ports or sockets. In this way, the charge accumulated on the ti...

Abstract

An electrostatic discharge protection device for a circuit board at least includes a non-conductor layer and a conductor layer. The non-conductive layer is in contact with the circuit board to insulate the conductive layer from the circuit board. The conductive layer disperses the charge accumulated at the tip portion of the circuit board, improving the electrostatic discharge protection capability of the circuit board.

Description

technical field [0001] The invention relates to an electrostatic protection device, in particular to an electrostatic discharge protection device for a circuit board. Background technique [0002] General electronic devices, such as notebook computers, PDAs, etc., are easily damaged by electrostatic discharge (ESD) and affect the normal working status of machines or system devices. The instantaneous potential caused by the electrostatic discharge phenomenon is quite large, and because the design of IC components is becoming smaller and smaller, the electrostatic potential that may cause electrostatic discharge damage is also reduced. In practical applications, some high-speed components have an electrostatic potential of 30V may be damaged. [0003] The reason for electrostatic discharge is that a charged object will form an electric field, which will ionize the nearby gas and produce a discharge phenomenon. Whether it is a conductor or a non-conductor, it will generate an...
