Not bright cause
1, LED flexible lamp Belt packaging protection is not perfect, resulting in the transport process of light bead impact and damage.
2, LED flexible lamp with the welding point of the virtual welding phenomenon, the transport process of the vibration caused by the loss of solder joints and led to light.
3, LED flexible lamp with less solder content, solder joints easy to fall off
4, LED flexible lamp with solder quality is not good, led flexible lamp belt in the bending process of solder joints easy to produce brittle cracking, shedding phenomenon
5, LED flexible lamp with the bending angle is too large, resulting in LED flexible lamp with solder joint separation and copper foil is not bright
6, LED flexible lamp with the installation of excessive extrusion products, resulting in LED flexible lamp with chip damage or welding point deformation off and not bright
7, LED flexible lamp with PCB solder layer too thick, solder and PCB can not be fully integrated, is also a virtual welding phenomenon.
8, LED flexible lamp belt in the installation can not be distorted, if the distortion will cause the LED flexible light strips of the solder joints to fall off and lead to no light.
9, electrostatic burnout, because the LED is electrostatic sensitive components, no do not do a good job of electrostatic protection, it will cause chip burnout
