The led light strip in the living room is not bright, these 3 methods can not be solved, it means that it is time to change! The led light strip in the living room is not bright mainly due to 3 reasons, including static electricity burnout, high temperature damage, moisture burst at high temperature, the following specific Learn about.
①、Static burnout
Because LED is an electrostatic sensitive component, if the electrostatic protection is not done well in the production process, the LED chip will be burnt out due to static electricity, which will cause the false death of the LED strip.
Solution: Strengthen electrostatic protection. All employees who come into contact with LEDs must wear anti-static gloves and electrostatic rings in accordance with regulations. Tools and instruments must be grounded.
②、High temperature damage
The high temperature resistance of LEDs 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, resulting in LED Feign death phenomenon of light strips.
Solution: Do a good job in the temperature control of reflow soldering and soldering iron, implement a special person responsible for special file management, and use a temperature-controlled soldering iron for the soldering iron to effectively prevent the high temperature of the soldering iron from burning the LED chip.
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 suffer from the humidity in the LED package due to the high temperature and long time period during reflow soldering. Thermal expansion causes the LED package to burst, which indirectly causes the LED chip to overheat and be damaged.
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 LEDs used are uniform. There will be no moisture absorption.
