Static electricity is undoubtedly a demonic existence for electronic components. The impact of static electricity on electronic components mainly includes the following aspects:
(1) Electrostatic adsorption of dust reduces the insulation resistance of components (shortens the service life).
(2) Electrostatic discharge damages the components and makes the components unable to work (completely destroy the components).
(3) The heat generated by the electrostatic discharge electric field or current causes damage to the components (potential damage).
(4) The electromagnetic field generated by electrostatic discharge has a large amplitude (up to hundreds of volts/meter) and a very wide spectrum (from tens of megabytes to several gigabytes), which will cause interference or even damage to the dot components (electromagnetic interference) if all components are Damage must be detected and eliminated in production and quality control, and has little impact on users.
In the process of production and processing of idea components around the world, countless static electricity damages cost tens of millions of dollars each year. The same is true for LED plant lights. Especially in the LED packaging process, any problem in any small link will be LED plant light chips cause damage, ranging from affecting the service life, and at worst, the dead light cannot be resurrected.
The static electricity of the human body can reach about 3000V, and its instantaneous voltage is enough to break down the chip structure of the LED plant light. The solution is the same as that of all manufacturers of idea components. The equipment should be grounded and the resistance should be controlled. Generally, the resistance is less than or equal to 4Ω, and some require more The grounding resistance should be less than or equal to 2Ω in high places or equipment.
The electrostatic charge of the human body is not exactly the same. It depends on the fabrics and clothing worn, personal physique, and even diet and routine habits. When you go to bed at night and take off your clothes, you will hear pops and flashes. This is the case The electrostatic voltage has reached 3000V.
The staff should wear anti-static clothing and static ring to prevent the damage of the LED plant light chip caused by the static electricity of the human body. Practitioners should receive basic anti-static training before they can start their jobs. If there is any illegal operation, they should be warned and instructed to attract attention.
