Why do electronics factories require employees to wear anti-static clothing
Why do electronics factories require employees to wear anti-static clothing? First of all, we must be clear about the composition of anti-static clothing. The anti-static clothing is made of special polyester filaments and high-performance permanent conductive fibers through a special process. This anti-static and dust-proof fabric has excellent and durable anti-static and dust-proof functions. , Can effectively release the static charge of the human body.
In the production process of the electronics factory, because the static voltage value on the clothing has greatly exceeded the electrostatic discharge damage threshold of many electrostatic sensitive devices during various activities, the sensitive devices may be caused when they touch or approach these components. Is damaged or broken down.
During the production, due to frequent activities of the staff, it is inevitable that friction will be generated and the clothing and shoes will be charged, especially when wearing high-insulating chemical fiber clothing, the charging will be aggravated. Since the human body itself is a good conductor, the charged clothing will cause the skin of the human body to be charged due to electrostatic induction, and a certain static voltage will also be formed.
For operators, there are two possible paths for electrostatic discharge, one is the discharge between the fingertip (skin) and the grounding conductor, and the other is the discharge between the work clothes and the grounding conductor. Both of these discharges may cause damage to electrostatic sensitive devices and cause irreparable losses.
To eliminate the hazards of static electricity, the human body’s own anti-static equipment is essential. For the first type of discharge hazard mentioned above, an anti-static wrist strap is the first choice, but it cannot eliminate the second type of discharge hazard. For the latter, it can only be eliminated by wearing anti-static clothing, so that the two-pronged approach can achieve the real effect of eliminating static electricity.
