Computer repairers need to wear an anti-static wrist strap
ESD wrist strap can be used in electronics factories, medicine, aerospace, precision machinery, etc. But you know that computer repairers also need to wear anti-static wrist straps. Why do you say that?
Most of the computer chips are semiconductor integrated circuits, and they may be broken down and damaged when encountering strong voltages. The static electricity generated by the human body can range from several thousand V to tens of thousands of V. The wrist directly introduces static electricity into the ground through the ground terminal of the electrostatic wrist without affecting the semiconductor components.
One thing to understand is that maybe your chip is damaged by static electricity and it can still be used. But you must not think that it is nothing, such as a CPU, maybe a certain line of his circuit is burned, and it can be used in time, which will also affect the life span, 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 out semiconductor components.
Now it seems necessary to wear an ESD wrist strap. Anti-static wrist strap is the most basic of anti-static equipment, and it is also a must-have for the most commonly used production line. It is not only very convenient in erection and operation, but also the most affordable in price. The reason is that it is through the wrist strap and grounding Wire, discharge the static electricity on the human body to the earth yes, so the wrist strap must be in contact with the skin when using it, and the grounding wire must also be directly grounded, and ensure that the grounding wire is unobstructed in order to achieve maximum effect.
