LED Flexible Strip demanding on the quality of the solder, even after numerous checks after testing and there was still not bright phenomenon. Automatic soldering expert Okada's technology engineers to analyze its causes, are summarized as follows: 1, LED lights with flexible solder less solder off easily; 2, LED lights with flexible solder joints Weld phenomenon during transport vibration caused by solder joints caused by shedding lights not bright; 3, LED lights with flexible packaging protection is imperfect, resulting in the transport process damaged by the impact lamp beads; 4, LED lights with flexible solder quality is not good, LED flexible light band bending joints prone to embrittlement process, shedding phenomenon; 5, LED lights with flexible installation over extruded products, leading LED Flexible Strip chip off damaged or deformed joints without light; 6, LED lights with flexible circuit board solder layer is too thick, welding, soldering and circuit board can not be completely fused together, but also a Weld phenomenon; 7, LED Flexible Strip can not be twisted during installation, if it will cause distortion Flexible LED with lead solder joints shedding light; 8, LED lights with flexible installation bending angle is too large, resulting in LED lights with flexible joints and copper separation result does not shine.
