The necessity of anti-static technology in the computer room

1. introduction

Anti-static technology in the computer room is part of the protection of the computer room in the protection category. Static electricity generated due to various reasons is one of the most frequent and most difficult to eliminate. Static electricity will not only cause random failures in the operation of the computer, but also cause the breakdown and destruction of certain components, such as CMOS, MOS circuits, and dual-level circuits. In addition, it will also affect the normal work and physical and mental health of operators and maintenance personnel. The application of computers in various fields of national economy, such as weather forecasting, aviation management, railway transportation, postal and telecommunication services, microwave communications, securities operations, financial and financial services, artificial satellites, missile launches, etc., has become increasingly popular and in-depth. As the name of the economy is closely related, once the computer system fails in operation, especially if the large-scale failure will bring huge losses to the country's economic belt, the resulting political impact can not be ignored.

Static problems in the equipment room and the problems caused by static electricity protection are not only difficult to detect by hardware personnel, but also sometimes caused by software personnel mistakenly thinking that it is a software failure. In addition, when the static electricity is discharged by a human body to a computer or other device (namely, the so-called ignition), when the energy reaches a certain level, it also gives people the feeling of electric shock, causing the operating system to be a mental burden for maintenance personnel and affecting work efficiency. How to prevent the harm of static electricity not only involves the design of the computer, but also has a great relationship with the structure and environmental conditions of the computer room. When building and managing computer rooms, it is always an important issue to analyze the effects of static electricity on computers, study their fault characteristics, identify the root causes of static electricity, and formulate measures to reduce or eliminate static electricity.

The impact of static electricity on computers The impact of static electricity on computers is mainly reflected in the impact of static electricity on semiconductor devices. It can be said that the semiconductor device is sensitive to static electricity, that is, the computer is sensitive to static electricity. With the development of the computer industry, the major component semiconductor devices that make up computers have also been rapidly developed. Due to the high density and high gain of the semiconductor device, the high speed, high density, large capacity, and miniaturization of the electronic computer are also promoted. At the same time, it has also led to the semiconductor devices themselves becoming more and more sensitive to electrostatic reactions. There are two types of electrostatic effects on computers. One is component damage, the other is causing computer malfunctions or operational errors. Component damage is mainly used in computers, large-scale integrated circuits, and it also has a certain influence on bipolar circuits. For the early MOS circuits, when the electrostatic charged body (usually high electrostatic voltage) is primary to the legs of the MOS circuit, the static electrification body discharges them, causing the MOS circuit to breakdown. In recent years, the MOS circuit has high density and high speed. With low prices, it has been widely used and developed. At present, most MOS circuits have a termination protection circuit, which improves the anti-static protection capability. In spite of this, when using it again, especially when repairing and replacing, it is also necessary to pay attention to electrostatic stars, and excessive static voltage will still cause breakdown of the MOS circuit. Electrostatic discharge caused by malfunction or operation error is caused by the static electricity charged to touch the computer, discharge to the computer, it may cause the computer logic component input error signal, causing computer error. In severe cases, the calculation program sent to the computer will be disordered. In addition, static electricity also has a significant effect on the external equipment of the computer. When a display device with a cathode ray tube is disturbed by static electricity, the image may be disordered, and the display may not be blurred. Static electricity will also cause malfunctions of modems, network cards, faxes, etc., and printers that have poor alignment.

4. Computer static fault features:

1). Computer malfunction due to static electricity

a. The season in which static electricity faults occur is mainly the drying season of winter and spring, which means that static electricity changes with humidity.

b. Electrostatic-induced failures are more accidental and less reproducible. They are generally random failures. Therefore, it is difficult to find out the cause of the induction.

c. Electrostatic and computer room floor. The furniture used is related to the staff’s overalls.

d. When an electrostatically induced electronic computer malfunctions, it often occurs when the human body or other insulator comes in contact with a computer device.

2). Causes of Computer Failure Caused by Electrostatic Discharge

a. Due to the instantaneous current flowing through the chassis, induced noise is generated on the signal line and the power line.

b. Due to the high voltage generated by the static electricity, a safe potential change occurs at the chassis ground, which causes a logically generated potential change.

c. Electromagnetic waves generated by the contact portion during electrostatic discharge give rise to radiated noise of the signal.

In short, BlueBest anti-static floor is the must-use product in our production workplace. It is also for our work efficiency is higher and the machine is used for a longer period of time.
