Flip Chip COB LED features compared with the classic COB LED:
(a) and 1(b) respectively show the schematic diagrams of a traditional wire-bond COB Chip and no wire-bond flip COB chip. In Figure 1(a), a traditional COB chip is bonded on the MCPCB substrate by bonding epoxy and connects to the circuit electrodes via two bonding wires. The thermal energy generated by the LED chip is dissipated through the chips’ sapphire substrate, bonding epoxy, followed by a MCPCB dielectric layer before reaching the metal core. On the other hand, the flip COB chip shown in Figure 1(b) has the LED chip directly bonded on the circuit electrodes without the bonding wire and epoxy. The heat generated by the LED is coupled through the chip bonding pads, circuit electrodes, MCPCB dielectric layer, and then diffused into the metal core. In comparison, the flip COB chip exhibits less thermal resistance as its thermal dissipating path excludes the sapphire substrate and bonding epoxy that are materials having higher thermal resistance.
