LED lamp belt in production will inevitably produce undesirable, and the LED lamp with defective maintenance is a need to pay special attention to. Because the LED light in the maintenance is very easy because of improper operation, and led to the scrap of the lamp band.
Because the LED is electrostatic sensitive components, if the maintenance of LED lights do not do a good anti-static measures, will burn the LED, resulting in waste. It is necessary to pay attention to the use of iron soldering irons, while maintenance personnel must also do anti-static measures (such as wearing electrostatic ring and anti-static gloves, etc.)
2. Continuous high temperature
LED lights with two important components of LED and FPC, are not able to continue to withstand high temperature products. FPC if in the continuous high temperature or more than its bearing temperature, will make the FPC covered film blister, directly caused by LED lamp scrap. At the same time, the LED can not continue to withstand high temperature, in the high temperature time, the chip will be burned by high temperature. Therefore, the maintenance of LED lights used in the soldering iron must be used to control temperature, the temperature is limited to a range, no arbitrary changes and settings. In addition, even so, you need to pay attention to the maintenance of iron in the foot of the LED stop time more than 10 seconds, if more than this time, it is likely to burn the LED chip.
3. Short Circuit
Many LED lights are bad because there is a short circuit in the foot, before the maintenance must find out the real bad reasons. Otherwise, the sudden replacement of bad led, again when the power will continue to cause the LED chip is short-circuit current breakdown. Therefore, before replacing the new LED, must first find out the real cause of the bad, the remedy can be more effective.
