How to eliminate static electricity in the human body
Anti-static wrist strap: It is used to discharge static electricity from the human body. Widely used in a variety of electronic operating stations.
Anti-static shoes: Anti-static shoes can guide static electricity from the human body to the ground, thus eliminating static electricity from the human body, and effectively suppressing the dust generated by people moving around in the clean room.
Anti-static overalls: Prevent static build-up on clothing.
Anti-static gloves: If the operator needs to hold static sensitive components frequently, it is necessary to wear anti-static gloves.
In the production process of the electronics factory, because the static voltage value of the clothing in the various activities is much higher than the electrostatic discharge damage threshold of many static sensitive devices, it may cause sensitive devices when touching or approaching these components. Damaged or broken down.
In the production process, due to the need for frequent activities, it is inevitable that friction will cause the clothing and shoes to be charged, especially when wearing high-insulation chemical fiber clothing. Since the human body itself is a good conductor, the charging of the clothing will cause the human skin to be charged around the body due to electrostatic induction, and a certain static voltage is also formed.
For the operator, there are two possible channels for electrostatic discharge, one is the discharge between the fingertip (skin) and the ground conductor, and the other is the discharge between the overalls and the ground conductor. Both of these discharges can cause damage to static-sensitive devices, causing irreparable damage.
In order to eliminate the electrostatic hazard, the body's own anti-static equipment is indispensable. For the first type of discharge hazard mentioned above, the anti-static wrist strap is the first choice, but it cannot eliminate the second discharge hazard. For the latter, you can only use anti-static clothing to eliminate, so that the two-pronged approach can achieve the real effect of eliminating static electricity.
