Static protection manufacturers analyze the static protection of LED production workshops
Static electricity protection is to eliminate static electricity or control the static voltage within the allowable range to avoid injury. In short, it is to prevent static electricity from accumulating to a certain extent, destroying certain electronic products, leading to unnecessary scrap, reducing production costs and avoiding waste. The electrostatic protection of LED production workshops, most manufacturers now have different degrees of ESD hidden dangers. The main manifestations are as follows:
1. In terms of eliminating static electricity on the human body, if the wristband is equipped with wireless technology, it will not work at all. Because the working principle of the cordless wristband is self-induction ionization discharge, it usually produces an effect when the electrostatic voltage exceeds 2000V, and the voltage has exceeded the electrostatic destruction voltage of the LED.
2. Anti-static work chairs 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 ESD electrostatic protection, we analyze electrostatic protection from a professional perspective and submit a satisfactory electrostatic protection system for each factory area.
First of all, in order to achieve the purpose of anti-static, we should systematically analyze to achieve the following basic conditions
1. Implement protection measures for human body electrostatic discharge;
2. Implement the guarantee of electrostatic protection for production equipment in the workshop;
3. Strive to make the production workshop and surrounding environment meet the anti-static requirements;
4. Improve the system, formulate operating specifications, establish a strict internal audit system to ensure that the system can effectively focus on the technical training of employees; formulate technical standards for electrostatic protection products to ensure the quality of protection products.
5. Install and implement monitoring equipment, conduct static electricity detection at all times during work, and remind employees at the first time to minimize losses.
6. Establish an ESD static monitoring system, and conduct regular data analysis and discussion to improve defects. It can also perform key inspections on products with static electricity generation time.
Second, implement a rectification plan and install static monitoring equipment: wristband static monitoring equipment, equipment static monitoring equipment, temperature and humidity monitoring equipment, etc. The monitoring equipment will alarm in real time, and the ESD static electricity monitoring system will regularly sort out the occurrence of static electricity during this period, and it needs to be repaired and dealt with in time; before purchasing all protective equipment, measure the surface resistance value; employee anti-static clothes, hats, etc. . Test the surface resistance and friction voltage once a month; test the surface resistance and friction voltage after each cleaning; test the surface resistance of the anti-static table mat once a year. 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 tested once a month.
