The phenomenon of Electro Static Discharge (ESD) occurs when an object with the opposite polarity of static electricity is approached and produces a snap sound accompanied by light.
The electrical noise generated by electrostatic discharge will interfere with the logic circuit and cause random misaction or calculation error of the computer.
Static electricity can also break down computer chips, and there is no trace of it. It can be said that static electricity is the invisible killer of computers. And why is that?
Because the CPU chip in the computer, the memory chip and the very large scale integrated circuit chip on the motherboard are mostly CMOS (composite metal oxide semiconductor) materials, CMOS devices have the advantages of high integration, low cost, fast speed and low energy consumption, so they are widely used.
However, one of its \"fatal\" weaknesses is that the input impedance is large and it is easy to be broken down by static electricity.
