Compared with traditional packaging technology, what are the advantages of COB technology?

1. 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 in dispensing, separation, light splitting and packaging is much higher. Compared with traditional SMD, it can save 5% of any and material costs.

2. Advantages of low thermal resistance

The system thermal resistance structure of traditional SMD packaging is: chip-die bonding adhesive-solder joint-solder paste-copper foil-insulation layer-aluminum material. The system thermal resistance of the COB package is: chip-die-bonding glue-aluminum. The system thermal resistance of COB packaging is much lower than that of traditional SMD packaging, so the service life of LED lamps in COB packaging is greatly improved.

3. Light quality advantages

The traditional SMD package pastes multiple discrete devices on the PCB board to form the light source component of the LED application in the form of a chip. This method has the problems of point light, glare and ghosting. The COB package is an integrated package and a surface light source, with a large viewing angle and easy adjustment, reducing the loss of light refraction.

The traditional SMD packaging method is to paste multiple different devices on the PCB board to form LED light source components. The light source made by this packaging process generally has the problems of electro-optic, ghosting and glare. The COB light source does not have the above problems. It is a surface light source with a large viewing angle and easy adjustment of the angle, which reduces the loss of light due to refraction.

4. Application advantages

The application of COB light source is very convenient, and it can be directly applied to lamps without other processes. However, the traditional SMD package light source still needs to be patched first, and then fixed on the PCB board through reflow soldering. It is not as convenient as COB in application.
