LED light strips will inevitably have defects in production, and the repair of defective LED light strips is a matter that requires special attention. Because the LED light strip is easy to be scrapped due to improper operation during maintenance.
1. Anti-static
Because LEDs are electrostatic sensitive components, if anti-static measures are not taken when servicing the LED strips, the LEDs will be burned out, causing waste. It should be noted here that the soldering iron must use an anti-static soldering iron, and the maintenance personnel must also take anti-static measures (such as wearing static rings and anti-static gloves, etc.)
2. Continuous high temperature
The two important components of LED strips, LED and FPC, are products that cannot continue to withstand high temperatures. If the FPC continues to high temperature or exceeds its withstand temperature, the cover film of the FPC will bubble, which will directly cause the LED strip to be scrapped. At the same time, LEDs cannot withstand high temperatures continuously, and their chips will be burnt out at high temperatures for a long time. Therefore, the soldering iron used when repairing the LED light strip must be a temperature-controlled soldering iron, the temperature is limited to a range, and it is forbidden to change and set at will. In addition, even so, it is necessary to pay attention to the soldering iron not to stay on the LED pin for more than 10 seconds during maintenance. If it exceeds this time, it is likely to burn the LED chip.
3. Short circuit
Many LED strips are defective because there is a short circuit at the pin, so you must find out the real cause of the defect before repairing. Otherwise, after rashly replacing the bad LED, it will continue to cause the LED chip to be broken down by the short-circuit current when the power is turned on again. Therefore, before replacing a new LED, you must first find out the real cause of the defect, and prescribe the right medicine to get twice the result with half the effort.
