1. The packaging protection of the LED flexible light strip is not perfect, causing the lamp bead to be damaged by impact during transportation.
2. The welding point of the LED flexible light strip has a phenomenon of virtual welding, and the vibration during transportation causes the welding point to fall off and the light strip does not light up.
3. The LED flexible light strip has a small amount of solder, and the solder joints are easy to fall off
4. The soldering tin quality of the LED flexible light strip is not good, and the solder joints of the LED flexible light strip are prone to brittle cracking and falling off during the bending process.
5. The bending angle of the LED flexible light strip is too large when it is installed, which causes the LED flexible light strip to separate from the copper foil and cause no light.
6. Excessive squeezing of the product during the installation of the LED flexible light strip causes damage to the LED flexible light strip chip or the deformation of the solder joints and does not light up
7. The solder mask of the LED flexible light strip 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 LED flexible light strip cannot be twisted during installation. If it is twisted, it will cause the solder joints of the LED flexible light strip to fall off and cause no light.
9.Static burnout, because LED is an electrostatic sensitive component, if there is no protection against static electricity, it will cause the chip to burn out.
