Introdução
The COB packaging process is not much different from the SMD production process, but the packaging efficiency of COB packaging is much higher in dispensing, separation, spectroscopy and packaging. Compared with traditional SMD, it can save 5% of any costs and materials.

Compared with traditional packaging technology, what are the advantages of COB technology?
High packaging efficiency and cost saving
The COB packaging process is not much different from the SMD production process, but the packaging efficiency of COB packaging is much higher in dispensing, separation, spectroscopy and packaging. Compared with traditional SMD, it can save 5% of any costs and materials.
Advantages of low thermal resistance
The system thermal resistance structure of traditional SMD packaging is: chip – die bonding glue – solder joints – solder paste – copper foil – insulation layer – aluminum material. The system thermal resistance of COB packaging is: chip-die die glue-aluminum material. The system thermal resistance of COB packaging is much lower than that of traditional SMD packaging, so the service life of COB packaged LED lamps is greatly improved.
Light quality advantage
Traditional SMD packaging attaches multiple discrete devices to the PCB in the form of patches to form light source components for LED applications. This approach has problems with spot light, glare and ghosting. The COB package is an integrated package and a surface light source. It has a large viewing angle and is easy to adjust, reducing the loss of light refraction.
Application advantages
COB light source is very convenient to apply and can be directly applied to lamps without other processes. The traditional SMD packaged light source needs to be mounted first and then fixed on the PCB board through reflow soldering. It is not as convenient as COB in application.
