LED strips will inevitably have production defects, and the repair of defective LED strips is a problem that requires special attention. LED strips are prone to damage due to improper handling during maintenance.
Since LEDs are static sensitive components, if you do not take antistatic measures when repairing LED strips, it will burn out the LEDs and cause waste. It should be noted here that the soldering iron must use an anti-static iron, and maintenance personnel must also take anti-static measures (such as wearing static rings and anti-static gloves).
2. Continuous high temperature
Two important components of LED strips, LEDs and FPCs are products that cannot sustain high temperatures. If the FPC is under continuous high temperature or exceeds its temperature resistance, it will cause the cover film of the FPC to foam, which will directly cause the LED strip to be cut. At the same time, LEDs cannot sustain high temperatures continuously, and if the temperature is long, their chips will burn through high temperatures. Therefore, the solder used to maintain the LED strip must use temperature-controlled solder to limit the temperature within a range, and it is forbidden to arbitrarily change and set it. Also, even then, be aware that you don't need to block the LED pins for more than 10 seconds during maintenance. If you exceed this time, you can burn out the LED chip.
3. Car circuit
Many LED strips have defects due to shorting of the feet. Be sure to find out the real cause of the defect before repairing it. Otherwise, after replacing the bad LED, when the LED is powered on again, the chip of the LED will continue to be decomposed by the short circuit current. So before you replace the new LED, you have to find out the real bad first, so you can do more with less.
