Current refers to the flow of charge from one point to another, at different potentials. In other words, a difference in potential causes a flow of current. This flow of charge or current is the basis of all electrical and electronic engineering because it represents the electrical performance of energy.
However, this is a great paradox, when the same charge can not flow smoothly, but rather an unexpected, sudden current flows, for which the electronic device is identical detrimental this The condition is called electrostatic discharge or ESD for short. The reason for this danger is that solid-state electronic devices, including semiconductor materials and components, can cause irreversible damage when subjected to electrostatic discharge.
therefore, does not require too much emphasis can recognize a full of millions of dollars worth of electronics components consisting of a solid data center needs to be protected in order to prevent such a charge, to avoid damage to property , data loss and loss of data center operations company image and reputation.
to do a further precaution, we need to know more about this phenomenon itself. Due to some simple activities, electrostatic discharge may occur. For example, when a person walks on a carpet, static electricity may be generated, and electrostatic induction may also generate an electrostatic discharge. There are three main modes for explaining the phenomenon of electrostatic discharge, which are human body mode, charged device mode and mechanical mode. I won't explain the details of these patterns in this relatively short article, but basically these patterns mimic the intensity and source of electrostatic discharge phenomena to varying degrees. For example, if a person walks on a carpet and obtains a positive or negative charge, and then comes into contact with a comprehensive circuit of different potentials, an electrostatic discharge will occur between the human body and the electronic components, which is the human body mode of electrostatic discharge.
electrostatic discharge spark may have or may not spark. I believe that everyone in you has seen thunder and lightning during the rainy season. Lightning is also an instantaneous discharge, albeit at a large scale and with a large potential difference. However, as long as a few volts of electrostatic discharge may be sufficient to damage several types of electronic devices. This damage can make a part of the equipment or the entire equipment unusable, or cause a potential damage, the equipment can keep working, but its actual reliability and service life is much lower than a normal equipment.
simply understand what is electrostatic discharge, as well as various manifestations, is related to the next million dollar question of how to prevent the occurrence of such phenomena. Because the cost of a typical data center equipment is high, not to mention the value of valuable data and information storage in these machines. Because there are several electrostatic discharge modes, there are several ways to protect electronic devices in the data center.
a technique is the use of all types of anti-static clip, help make any electrostatic discharge to ground, thereby protecting equipment. A detailed analysis of these antistatic clips can be found in the "Application Report" by Texas Instruments experts.
all static-sensitive components should be handled with care, and should ensure that clothing and floor staff is antistatic. The same principle when
not apply to these devices work, in their packaging and transportation process, should use the same precautions.
technicians working on a computer data center, server and other electronic devices should ensure that he (or she) when intermittently contacting the metal surface, no machine is generated between the body and the potential difference between the electrostatic discharge .
should pay particular attention to the storm, and should try not to let the system work during the storm. We see and enjoy the spectacular spectacle of thunderstorms, but if you look at the security of electronic devices, thunderstorms are not so spectacular.
In addition to taking more preventive measures against individual equipment, the overall construction of the data center should also be carried out in accordance with the following lightning protection appropriate measures. These include the installation of appropriate lightning protection systems that have been inspected by the relevant authorities. Includes a wide range of equipment such as transient voltage surge suppressors and surge arresters.
data center should have a set of regulations, which, depending on the work, including the need to wear certain types of clothes to prevent damage from static electricity. These regulations should not only exist on paper. Staff at all levels should have an in-depth understanding of the phenomenon of electrostatic discharge and the potential losses that electrostatic discharge will bring to the company. These losses will eventually affect the interests of each employee.
understand the type of electrostatic discharge patterns and the possibility of damage, data center management should not be left to chance, it should provide appropriate protection measures and policies. A tiny static spark can cause catastrophic loss of the entire data center. It should be borne in mind: prevent problems before they happen.
