Jadisi: Home led strip lights repair method
Home led strip lights are gradually emerging in the decoration industry because of their lightness, energy saving, softness, long life, and safety. So what should I do if the light strip does not light up? The following lamp strip manufacturer Jadisi briefly introduces the repair methods of LED strips.
1. High temperature damage
The high temperature resistance of LED is not good. Therefore, if the welding temperature and welding time of the LED are not well controlled during the production and maintenance process, the LED chip will be damaged due to ultra-high temperature or continuous high temperature, which will cause the LED strip to be damaged. Feign death.
Solution: do a good job in the temperature control of reflow soldering and soldering iron, implement a special person responsible, and special file management; the soldering iron uses a temperature-controlled soldering iron to effectively prevent the soldering iron from burning the LED chip at high temperature. It should be noted that the soldering iron cannot stay on the LED pin for 10 seconds. Otherwise it is extremely easy to burn the LED chip.
2. static electricity burns out
Because LED is an electrostatic sensitive component, if the electrostatic protection is not done well during the production process, the LED chip will be burned out due to static electricity, which will cause the false death of the LED strip.
Solution: Strengthen electrostatic protection, especially the soldering iron must use anti-static soldering iron. All employees who come into contact with LEDs must wear anti-static gloves and electrostatic rings in accordance with regulations, and tools and instruments must be well grounded.
3. Moisture bursts under high temperature
If the LED package is exposed to the air for a long time, it will absorb moisture. If it is not dehumidified before use, it will cause the moisture in the LED package to expand due to the high temperature and long time period during the reflow soldering process. The LED package bursts, which indirectly causes the LED chip to overheat and damage it.
Solution: The storage environment of the LED should be constant temperature and humidity. The unused LED must be baked in an oven at about 80° for 6~8 hours for dehumidification before the next use, to ensure that the used LED will not have any Moisture absorption phenomenon.
Home led strip lights are still troublesome to repair. If it is only used on a small scale, it is better to replace a light strip directly. Home led strip lights on the market are not expensive. Hope this article can be helpful to everyone.
