1.What is COB ?

Chip-on-Board, or COB, refers to the semiconductor assembly technology wherein the microchip or die is directly 

mounted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or 

packaging as an individual IC. The elimination of conventional device packaging from COB assemblies simplifies the 

over-all process of designing and manufacturing the final product, as well as improves its performance as a result of the 

shorter interconnection paths.


2. What is COB Advantage ?

1) Reduced space requirements;
2) Reduced cost;
3) Better performance due to decreased interconnection lengths and resistances;
4) Higher reliability due to better heat distribution and a lower number of solder joints;
5) Shorter time-to-market



1. High class stores, shopping malls.


2. Hotel, entertainment places, beauty parlor lighting.


3. Meeting room, muti-fuction hall, exhibition hall.
