1. Anti static: As the LED is a static sensitive component, if the anti-static measures are not properly handled when the LED strip is being repaired, the LED will be burned, causing losses. It should be noted that the electric soldering iron should be anti-static, and the maintenance personnel must also prepare anti-static measures (such as wearing electrostatic rings and anti-static gloves).
2. Continuous high temperature: LED and FPC are the two main components of LED light strip. If FPC is continuing high temperature or exceeds its acceptance measurement, it will cause the cover film of FPC to crack, and indirectly lead to the scrapping of LED light strip. At the same time, LED can not withstand high temperature for a long time, and its chip will be burned by high temperature. Therefore, the electric soldering iron used for repairing the LED light strip is a temperature control electric soldering iron, which limits the measurement to a certain range and prevents arbitrary changes and settings. In addition, even so, it is also necessary to note that the electric soldering iron cannot stop at the LED foot position for more than 10 seconds during maintenance. If it exceeds a certain time, the LED chip will be burned.
3. Short circuit: Many LED light strips do not light up because there is a short circuit at the feet. Before maintenance, you must investigate the real reason why they do not light up. Otherwise, after hastily changing the LED that is not lit, the chip that forms the LED will be broken down by short circuit DC when the power is returned again. Therefore, in advance, we must first find the real reason why there is no light, and then we can get half the result with twice the effort.
