What is COB?
Chip on Board, or COB, refers to the semiconductor assembly technology where in the microchip or die is directly mou nted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or packing as and individual IC.
The elimination of conventional device packaging from COB assemblies simplifies the over all process of designing and manufacturing the product, as well as improves its performance as a result of the shorter interconnection paths.
What is COB advantages?
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.
Main advantages of LED downlight
1. High efficiency and energy-saving compared to conventional fluorescents which are equal bright, and consumes 70-80% less energy.
2. No RF interference, no buzzing noise, no UV radiation.
3. No fluorescent flickering.
4. No hazard of mercury or lead entering the environment.
5. Low power consumption, high intensity, low lumen attenuation.
6. Recessed mounted, maintenance free, easy installation.
7. Solid- state, high shock/ vibration resistant
