Electrostatic discharge protection on circuit board

Abstract

The present invention which is static electrical discharging protection for circuit is applied for two separated circuit boards. It works as that the second circuit board chip is not impacted by static electrical discharging current when static electrical discharging current is generated on the first circuit board so the second circuit board chip is protected from impact of static electrical discharging current.

Description

technical field [0001] This invention relates to electrostatic discharge protection on circuit boards, and more particularly to current protection paths in split circuit boards against electrostatic discharge strikes on other circuit boards. Background technique [0002] Typically, the surface of the human body accumulates an electrostatic charge that can be as large as several thousand volts. If you touch a metal object with your hands, especially a general IC chip or a circuit board embedded with an IC chip, the electrostatic charge on the body will be discharged to the IC chip or circuit board in an instant, which is called Electro Static Discharge (Electro Static Discharge, ESD). The electrostatic discharge current is likely to cause malfunction or damage of the IC chip. [0003] Please refer to figure 1 , which represents a schematic diagram of circuit board wiring of a known thin optical disc device. The circuit board of the thin disc device can be divided into two...
