The Reason Why The Aluminum LED Light Bar Does Not Light Up

1. The packaging protection of the aluminum LED light bar is not perfect, causing the lamp bead to be damaged by impact during transportation.

2. The welding point of the aluminum LED light bar has a phenomenon of virtual welding, and the vibration during transportation causes the welding point to fall off and the light bar does not light up.

3. The aluminum LED light bar has a small amount of solder and the solder joints are easy to fall off.

4. The soldering quality of aluminum LED light bar is not good, and the solder joints of LED flexible light bar are prone to brittle cracks and fall off during the bending process.

5. When the aluminum LED light bar is installed, the bending angle is too large, causing the solder joint of the LED flexible light bar to separate from the copper foil and cause no light.

6. When the aluminum LED light bar is installed, the product is excessively squeezed, which causes the LED flexible light bar chip to be damaged or the solder joints are deformed and fall off and do not shine.

7. The solder mask of the aluminum LED light bar circuit board is too thick, and the solder and the circuit board cannot be completely fused together during soldering, which is also a kind of virtual soldering phenomenon.

8. The aluminum LED light bar cannot be twisted during installation. If it is twisted, it will cause the solder joints of the LED flexible light bar to fall off and cause no light.
