LED Strip lights are not lit cause

- Apr 29, 2016 -

1, LED flexible light strip packaging to protect the irregularities, which led by the impact damage during transport.

2 welding points, LED flexible light strip virtual welding phenomena caused by vibrations during transport solder off and the led lights are not lit.

3, LED flexible light with small amount of solder, solder come off easily

4 bad solder quality, LED flexible light strip, LED flexible led strips in the bending process of welding point prone to cracking, loss

5, LED flexible light strips bending angle is too large, resulting in flexible LED lamp with lead solder and copper apart is not lit

6 excessive squeeze, LED flexible light strip installation led LED flexible led Strip deformation of solder joints of chip is damaged or fall off without

7, LED flexible light with circuit board solder mask layers too thick, welding solder and circuit board does not fully come together, but also a cold solder joint.

8, LED flexible light strip cannot be distorted when it is installed, if twisted will cause the LED flexible light with the solder off and the led is not lit.

9, static burn, because the LED is static sensitive components, without proper ESD protection measures, it will cause chips to burn out
