Static Electricity Protection in LED Production Workshop

The anti-static products and other equipment used in the workshop work area may have a resistance greater than 109 after a period of time. In order to achieve the purpose of anti-static, it is recommended to create the following four basic conditions: first, ensure the implementation of human protection measures; second, ensure the electrostatic protection of workshop production equipment; third, strive to make the production workshop and the surrounding environment meet the anti-static requirements; fourth, improve the system, formulate operating specifications, establish a strict internal audit inspection system to ensure the implementation of the system, pay attention to the training of employees' electrostatic awareness; formulate technical standards for electrostatic protective equipment to ensure the quality of protective equipment.

In terms of measurement and control methods, we add temperature and humidity monitoring to the work area, record the temperature and humidity every day, measure static voltage every month, test the surface resistance and friction voltage of employees' anti-static clothing and hats after each wash, and test the surface resistance of anti-static mats once a year. A human body comprehensive resistance tester is set up at the entrance of the workshop; the balance voltage and static dissipation time of the ion fan are measured once a month. Please take appropriate precautions during the production process. The following is for reference only:

Must be able to prevent static electricity generation: assemblers must wear anti-static clothing (such as anti-static clothes, hats, shoes, finger cots or gloves, etc.) during operation. It must be able to quickly dissipate static electricity on the surface or inside: assembly operators must wear anti-static wrist straps. (The wrist strap must be connected to the grounding system) Can provide shielding protection from sudden static discharge or electric field shock:

① The assembly table (workbench) must use an anti-static mat and be grounded.

②Anti-static component boxes must be used to hold LEDs.

③The soldering iron, foot cutting machine, tin furnace (or automatic reflow soldering equipment) all need to be grounded.

During the operation, avoid touching the pins of the light-emitting tube directly as much as possible, and try to touch the colloid part when taking it out. Grounding measures should completely prevent the generation of static electricity. The grounding of the workbench, soldering iron, pin cutting machine, tin furnace (or automatic reflow soldering equipment) must be led into the soil with a thick iron wire, and a large iron block must be tied to the end of the iron wire and buried below 1 meter from the ground surface. All grounding wires must be connected to the main line. If the anti-static ring worn by the operator has a lead-out wire, the lead-out wire must also be connected to the buried ground wire. Semi-finished product and finished product testing equipment also need to be grounded.

LED packaging bags and semi-finished product packaging materials should use anti-static sponge or packaging.
