1.PCB   10mm PCB with more flexible installation and wider application 2.LED   Flip-chip process, the chip is directly packaged on the PCB board, which makes the heat dissipation more excellent and the service life is longer. 3. Production No need to control the placement of the mounting led, so that the production efficiency is greatly improved, and not causing production defects such as LED offset and  solder paste lost 4.Pad    Tin plating prevents oxidation and prolongs service life 5.Chromatic Aberration Use Narrow spectral band chip&fluorescent glue design, no color difference, no dot, with excellent consistency 6.Beam angle Luminous diameter can reach 6mm wide,beam angle 180degree 7.Cost The chip light-emitting effect of 300 led or above per meter is much better than the patch lamp light-emitting effect of 700led per meter, and the cost is more advantageous.
