COB Energy-saving Indoor Full Color LED Advertising Wall
What is COB?
COB packaging, or Chip On Board, is to adhere the bare chip to the interconnect substrate with conductive or non-conductive glue, and then perform wire bonding to achieve its electrical connection. If the bare chip is directly exposed to the air, it is susceptible to contamination or human damage, which may affect or destroy the chip function. Therefore, glue is used to encapsulate the chip and bonding wires.
