First, high packaging efficiency, cost savings: COB packaging process and SMD production process is not much different, but COB packaging in the dispensing, separation, spectroscopy and packaging on the packaging efficiency to be higher, and traditional SMD compared to save 5% of any and material costs.

Second, the advantages of low thermal resistance: the traditional SMD package system thermal resistance structure: chip - solid crystal adhesive - solder joints - solder paste - copper foil - insulation layer - aluminum, COB package system thermal resistance: chip - solid crystal adhesive - aluminum, COB package system thermal resistance is much lower than the traditional SMD package system thermal resistance, so COB package LED lamps and lanterns service life is greatly improved.

Third, the light quality advantage: the traditional SMD package through the SMD form of multiple discrete devices pasted on the PCB board to form the LED application of the light source components, this practice exists point of light, glare and ghosting problems. COB package is an integrated package, is a surface light source, large viewing angle and easy to adjust to reduce the loss of light refraction.

The traditional SMD package is a number of different devices are pasted on the PCB board, composed of LED light source components. This encapsulation process is made of light sources generally have electric light, ghosting and glare problems. COB light source does not have the above problems, it belongs to the surface light source, large viewing angle and easy to adjust the angle, reducing the loss of light due to refraction.

Fourth, the application advantages: COB light source application is very convenient, no other process can be directly applied to the lamps. The traditional SMD package light source also needs to be first patch, and then through the reflow soldering way fixed on the PCB board. It is not as convenient as COB in application.

The above is the LCF editorial summary of the advantages of COB encapsulation technology and traditional SMD technology comparison analysis, in the foreseeable future, the use of COB encapsulation LED display must have a good market performance, let us look forward to it.
