Computer maintenance staff need to wear an anti-static wrist strap
ESD wrist strap can be used in electronics, medicine, aerospace, precision machinery, etc. But you know that computer maintenance staff also need to wear an anti-static wrist strap. Why do you say that?
Most of the chips of the computer are semiconductor integrated circuits. If a strong voltage is encountered, it may be damaged by breakdown. The static electricity generated by the human body is as small as several thousand V and tens of thousands of V. The wrist directly directs static electricity through the ground of the electrostatic wrist to the ground without affecting the semiconductor components.
One thing to understand is that your chip may be damaged by static electricity and it can be used. But you should never think that he has nothing, such as the CPU, maybe a certain line of his line will be burned, it can be used in time, it will also affect the life, just like a wire that is about to break. This is one of the reasons why everyone is not sensitive to static electricity. It is believed that static electricity will not burn semiconductor components.
It seems that it is necessary to wear an ESD wrist strap. Anti-static wrist strap is the most basic and most commonly used product in anti-static equipment. It is not only easy to set up and operate, but also most expensive in price. The reason is through wrist strap and grounding. The wire discharges the static electricity from the human body to the earth. Therefore, the wristband must be in contact with the skin when it is used. The grounding wire must also be directly grounded, and the grounding wire must be unobstructed to maximize its effectiveness.
