New measures for electrostatic protection in LED production workshops
Electrostatic protection is to eliminate static electricity or control the static voltage within an allowable range so that it does not cause harm. To put it simply, it is to prevent static electricity from accumulating to a certain level and breaking down some electronic products, causing unnecessary scrap rate, increasing costs, and causing waste.
The electrostatic protection of LED production workshops, everyone's practice, generally has hidden dangers to varying degrees. Mainly manifested in: 1. The static electricity of the human body, if the wrist strap is equipped with a cordless, it will not work at all. Because the working principle of the cordless wrist strap is self-inductive ionization discharge, it usually produces an effect when the electrostatic voltage exceeds 2000V, and this voltage has already exceeded the electrostatic destruction voltage of the LED. 2. The anti-static work chair and other tools used in the work area of the workshop, after a period of time, the resistance of the chair surface and backrest is greater than 108-1010Ω.
As a manufacturer of first-class light-emitting diodes, our customers have taken some effective new measures and gained certain experience and effects in electrostatic protection.
In order to achieve the purpose of anti-static, we listened to the suggestions of experts and mainly created the following four basic conditions. One is to ensure the implementation of human protection measures; the other is to ensure the electrostatic protection of the production equipment in the workshop; the third is to strive to make the production workshop and its surroundings The environment meets the requirements of anti-static; the fourth is to improve the system, formulate operating specifications, establish a strict internal audit system to ensure that the system is implemented, and focus on technical training for employees; formulate technical standards for electrostatic protection products to ensure the quality of protective equipment .
In terms of measurement and control methods, Beichen Optoelectronics has added temperature and humidity monitoring to the work area, recording temperature and humidity every day; measuring static voltage every month; measuring surface resistance before purchasing all protective equipment; employee anti-static clothing, hats, etc., check the surface once a month Resistance and friction voltage; test the surface resistance and friction voltage after each wash; test the surface resistance once a year for anti-static table mats. A comprehensive human body resistance tester is installed at the entrance of the workshop; the balance voltage and static dissipation time of the ion fan are once a month.
