COB (Epoxy and Silicone)

Chip on Board (COB) is an electronic assembly technique where semiconductor chips (or dies) are directly mounted and connected to a printed circuit board (PCB) or substrate, without individual packaging.

Benefits:

  • No package around each chip, resulting in reduced space requirements
  • Reduction in material and volume costs
  • Heat dissipation is more direct since the chip is close to the substrate


It is a process that offers more functional possibilities than standard methods while allowing for greater design flexibility.
