Precautions for production and storage of LED light strips and light strips

Precautions for production and storage of LED light strips and light strips During the production process of the LED strip, there will be a phenomenon of LED false death (that is, the LED does not light up). The reasons for this phenomenon are as follows: 1. Static electricity burns out 1:1 Because the LED is an electrostatic sensitive component, if the electrostatic protection work is not done well during the production process, the LED chip will be burned due to static electricity, which will cause the false death of the LED strip. 1:2 The measure to prevent this phenomenon is to strengthen electrostatic protection. All employees who touch LEDs must wear anti-static gloves and static rings in accordance with regulations, and tools and instruments must be grounded. 2. High temperature damage The high temperature resistance of 2:1 LED is not good. Therefore, if the welding temperature and welding time of 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 The phenomenon of suspended animation of the light strip.

2:2 The measures to prevent this phenomenon are: do a good job in the temperature control of reflow soldering and soldering iron, implement special person responsible, and special file management; the soldering iron uses temperature-controlled soldering iron to effectively prevent the high temperature of the soldering iron from burning out the LED chip. 3. Moisture bursts at high temperature 3:1 If the LED 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 affected by 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. 3:2 Solution: The storage environment of LEDs should be kept at constant temperature and humidity. Unused LEDs must be baked in an oven at about 80° for 6-8 hours for dehumidification before the next use, so as to ensure that the used LEDs are uniform. There will be no moisture absorption.
