The LED light bar needs to be anti-static
Because the LED is an electrostatic sensitive component, if you do not take anti-static measures when repairing the LED light bar, the LED will be burned out and cause 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 a static ring and anti-static gloves, etc.)
LED light bar cannot sustain high temperature
The two important components of LED light bar, LED and FPC, LED light bar are products that cannot continue to withstand high temperatures.
If the FPC continues to be at a high temperature or exceeds its withstand temperature, it will cause the FPC's cover film to bubble and directly cause the LED light bar to be scrapped.
At the same time, LEDs cannot withstand high temperatures continuously, and the LED strip chips will be burned out by the high temperature for a long time.
Therefore, the soldering iron used when repairing the LED light belt must be a temperature-controlled soldering iron, and 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 pins of the LED light bar for more than 10 seconds during maintenance. If this time is exceeded, the LED light bar chip may be burned out.
LED light bar anti-short circuit
Many LED light bars are defective because there is a short circuit at the pin.
Before repairing, it is necessary to find out the real bad reason of the LED light bar.
Otherwise, after rashly replacing the bad LED light bar, it will continue to cause the chip of the LED light bar to be broken down by the short-circuit current when the power is turned on again.
Therefore, before replacing a new LED light bar, we must first find out the real reason for the bad LED light bar, so that the right remedy can get twice the result with half the effort.
