Static Protection
LEDs are semiconductor devices and are more sensitive to static electricity, especially for white, green, blue, and purple LEDs to prevent and eliminate static electricity.
1. The generation of static electricity:
① Friction: In daily life, any two objects of different materials contact and then separate, and static electricity can be generated. The most common way to generate static electricity is to generate electricity by friction. The better the insulation of the material, the easier it is to generate electricity by friction. In addition, any two objects with different materials can be separated after contacting them, which can also generate static electricity.
② Induction: For conductive materials, because electrons can flow freely on its surface, if it is placed in an electric field, because the same sex repels and the opposite sex attracts each other, positive and negative ions will be transferred, and charges will be generated on the surface. .
③ Conduction: For conductive materials, because electrons can flow freely on its surface, such as contact with a charged object, charge transfer will occur.
2. The harm of static electricity to LED:
① Due to the heat generated by the instant electric field or current, the LED is locally injured. The leakage current increases rapidly and can still work, but the brightness is reduced and the life span is damaged.
②Due to the electric field or current destroying the insulating layer of the LED, the device cannot work (completely destroyed), and it appears as a dead light.
3. Electrostatic protection and elimination measures:
For the entire process (production, testing, packaging, etc.) all employees who are in direct contact with the LED must take measures to prevent and eliminate static electricity, mainly
1. Lay anti-static floor in the workshop and do a good job of grounding.
2. The workbench is an anti-static workbench, and the production machine is well grounded.
3. The operator wears anti-static clothes, anti-static wristbands, gloves or foot rings.
4. Application of ion fan.
5. Do a good job of grounding the soldering iron.
6. The packaging is made of anti-static materials.
