How to efficiently and quickly repair damaged led project light strips?
1. Moisture bursts at high temperature:
If the LED light strip package is exposed to the air for a long time, it will absorb moisture. If it is not dehumidified before use, the moisture in the LED package will be thermally expanded during reflow soldering due to the high temperature and long time period during reflow soldering. , causing the LED package to burst, which indirectly causes the LED chip to overheat and damage. Repair measures: The storage environment of LED light strips should be kept at a constant temperature and humidity. Unused LED light strips should be baked in an oven at about 80° for 6-8 hours before the next use for dehumidification treatment. There will be moisture absorption.
2. Electrostatic burnout:
Because the LED engineering light strip is an electrostatic sensitive component, if the electrostatic protection work is not done well in the production process, the LED chip will be burned out due to static electricity, which will lead to the occurrence of suspended animation of the LED light strip. Repair measures: The measure to prevent this phenomenon is to strengthen electrostatic protection. All employees who come into contact with LEDs must wear anti-static gloves, electrostatic rings, and ground tools and instruments in accordance with regulations.
3. High temperature damage:
The high temperature resistance of LED strips is not good. Therefore, if the welding temperature and welding time of LEDs are not well controlled during production and maintenance, the LED chips will be damaged due to ultra-high temperature or continuous high temperature, resulting in LED lights. The phenomenon of suspended animation. Repair measures: The measures to prevent this phenomenon are to do a good job of temperature control of reflow soldering and soldering iron, implement special personnel in charge, and file management; the soldering iron adopts a temperature-controlled soldering iron, and the soldering iron burns out the LED chip at high temperature.
