What is COB Package technology?

COB package is called Chips on Board (COB), which is a technology to solve the problem of LED heat dissipation. Compared with in-line and SMD, it is characterized by saving space, simplifying packaging operations, and has an efficient thermal management method.

The COB package is chip on board, which is to stick the bare chip on the interconnection substrate with conductive or non-conductive adhesive, and then perform wire bonding to achieve its electrical connection. If the bare chip is directly exposed to the air, it is susceptible to pollution or artificial damage, which affects or destroys the function of the chip, so the chip and the bonding wire are encapsulated with glue. People also call this form of packaging soft package.

COB ADVANTAGES 

1. Direct chip welding without brackets, high-density packaging can be achieved. 

2. 
   

2. Using PCB board to dissipate heat, reduce the thermal resistance of the chip, and improve the reliability and stability. 

3. It is cured by epoxy resin to improve the protective performance. To 

4. Increase the viewing angle to bring a better visual experience.

5. The conversion of LED unit from "point" light source to "surface" light source is realized, and the picture is more uniform.

6. Significantly improve the contrast of the dissplay screen, greatly eliminate the graininess,and            effectively reduce the light intensity Radiation, eliminates moire and glare, and is not easy to cause    visual fatigue.

Strong protection

Full board epoxy resin seal, with waterproof, moisture-proof, dust-proof, anti-collision, anti-greasy,

anti-oxidation, anti-static properties, and has the characteristics of abrasion resistance and easy cleaning.
