Hello everyone, I am Xiaobian Qinmeng today, let ’s introduce the problem of how to disassemble the LED lamp beads to remove the LED lamp beads. The following is the summary of Qinmeng on this issue and related issues. Let’ s take a look. Catalog Navigation:1. How to remove LED lamp beads 2. How to remove LED lamp beads 3, LED lamp beads new methods 4. How to remove LED lamp beads 5. How to remove bad LED lamp beads removed LED lamp beads are removed LED lamp bead is a general term for semiconductor emitting diode. Take off the weld. In the lighting light, the patch -type lamp beads are mostly welded without pins and directly welded on the circuit board. They were disassembled with electric iron and welded. In particular, there were heat dissipation welds in the middle of the lamp beads.Use the welding table to heat the lamp bead to dissolve the tin, and remove the bad ones. You can also use a hot air gun to heat the hot beads. When there is no tool, you can also use a lighter to replace the welding platform. If it is removed, the tin should be supplemented by a low temperature welding wire or a low -temperature welded paste at the welding joint. LED lamp beads are removedSpecialized maintenance of LED lamp beads for disassembly is a dedicated heating iron plate. Put the panel with lamp beads on the heating iron plate. You can easily remove it in a few seconds. And install it again. The advantage of this method is fast, without damage to LED. The general amateur maintenance is disassembled and the LED can only be used. Pay attention to putting it lightly. The temperature of the soldering iron cannot be tuned too high. Generally, it should not exceed 300 degrees Celsius, otherwise the lamp beads will be scalded. Storo the side of the lamp bead first, gently pry the end with a thin blade, and then blanch the other side. Pay attention to quickly and accurate the whole process. The same is true when welding. You must pay attention not to stay on the lamp bead for a long time. LED lamp beads disassemble the new method 1, the disassembly and replacement method of general aluminum substrate LED lamp beads needs to be determined according to different circumstances. The plate will also be in the bright place, so it will be easier to replace. First, use the soldering iron to heat the two welding joints to remove the bad lamp beads, and then use the soldering iron to flatten two pads. Do not remain too much welded so that the lamp beads can be closely attached to the aluminum base plate. Then put the new lamp beads in the original positive and negative electrode in the original place, then order a little welding at the pins, and hold the lamp bead with your fingers to weld it. In addition, it is best to apply some heat -conducting silicon grease on the circular pad in the middle to reduce its thermal resistance. 2. For watch stickers such as 5730, the disassembly method will look more troublesome. You can remove the hot air gun and the electric soldering iron down, as long as it does not destroy the aluminum substrate. Then use the soldering iron to remove the excessive welding, leaving only a thin layer, and then click the welding to put the lamp beads in the original direction. The next step of welding must be started from the back, because the front pad is too hidden, the soldering iron will not be able to start, and it will easily scorch the gels of the lamp with a hot air gun. Find the position of the lamp beads on the back of the aluminum substrate, and then heat it with a large tile or hot air gun until the front weld melts the lamp beads to welded.LED lamp beads are removed LED lamp bead needs to use a hot air gun to blow it from the substrate. Because there is a welding point in the center of the back of the LED lamp bead, there is no way to weld it on the substrate. How to remove the bad LED lamp beads can be removed with a hot air gun. The method is as follows: The temperature of the hot air gun is adjusted to 320 °, and the wind speed is adjusted to 4. Use tin foil to cover the lamp beads around the bad lamp beads, and then heat it to the bad lamp beads to remove it. Then change the new lamp bead to go up. Do not wipe it with a wet rag immediately after the light is turned on, which will easily cause danger. I hope my answer can help you aken the above is the answer to how to disassemble the LED lamp beads to disassemble the LED lamp beads and answer questions and related questions. I hope it will be useful to you [responsible editor: Qinmeng] |
