LED lamp belt in the production will inevitably produce bad, and for the LED lamp with bad products maintenance is a matter of special attention.
Because LED lamp belt in the maintenance is easy because of improper operation, resulting in the scrap of LED lamp belt.
1, anti-static Because LEDs are electrostatic sensitive components, if the maintenance of LED light belt does not do a good job of anti-static measures, will burn the LED, resulting in waste.
It is important to note here that the soldering iron must be used to prevent static electric soldering, at the same time maintenance personnel must also do a good job of anti-static measures (such as wearing electrostatic ring and anti-static gloves, etc.)
2, continuous high temperature LED lamp Belt Two important components of LED and FPC, are not sustainable high temperature products. If the FPC in the continuous high temperature or exceed its bearing temperature, it will make the FPC cover film foaming, directly resulting in LED lamp belt scrapped. At the same time, LEDs can not continue to withstand high temperatures, in the high temperature time, its chip will be burned by the high temperature. Therefore, the maintenance of LED light belt used in the soldering iron must be the use of temperature control soldering iron, the temperature is limited to a range, the prohibition of arbitrary changes and settings.
In addition, even so, it is important to note that the soldering iron does not stay in the LED's feet for more than 10 seconds during maintenance, and if it exceeds this time, it is likely to burn the LED chip.
3. Short Circuit Many LED lights are bad because there is a short circuit at the foot, it is important to find out the real bad causes before maintenance. Otherwise, after the rush to replace the bad led, the power will continue to cause the LED chip by short-circuit current breakdown. Therefore, before replacing the new LED, we must first find out the real cause of the bad, the right medicine to do more with less
