why led strip cant light up

Date:2015-11-24

1, LED lights with flexible packaging protection is imperfect, resulting in the transport process damaged by the impact of lamp beads. 2, the welding point Flexible LED strip Weld phenomenon, caused by vibration during transport and lead solder off lights not bright. 3, LED lights with flexible solder less solder off easily 4, LED lights with flexible solder poor quality, LED lights with flexible joints in the bending process prone to embrittlement, shedding phenomenon 5, LED lights with flexible installation bending angle is too large, resulting in LED lights with flexible joints and bright copper separation lead 6, excessive extrusion LED lights with flexible installation products, leading LED lights with flexible joints deformed chip off damaged or not bright 7, LED lights with flexible circuit board solder resist layer is too thick, solder and board can not completely fused together during welding, but also a Weld phenomenon. 8, LED flexible light strip can not be twisted during installation, if twisted words will cause the LED lights with flexible joints and lead to shedding light. 9, electrostatic burned, because LED is an electrostatic-sensitive components, there is no good static protection, can lead to chip burn.
