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 overall 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-marketAbout Products:
Application:General commercial & architectural lighting,
hotel, restaurant, shop, office, theater, garage, hospital,
corridor, library and warehouse etc. /* January 22, 2024
