Solution to Make Flexible PCB LED Strip Design Into Reality in 2022(Part 3)


Part 3: Flexible PCB LED Strip Assembly: How LEDs are Assembled on FPC

LEDs (light-emitting diodes), or LED chips, are semiconductor parts having a P-N junction that allows current to flow in only one direction and transforms electric energy into light.

There are three methods to mount LED chips on PCBs:

Wiring bonding - -using a gold wire to connect the LED chip pin and the PCB.

Tape automated bonding -- using a copper foil to connect the LED chip pin's bump and the PCB.

Flip-chip - -the LED chip pin's bump and the bump of the PCB pad are directly connected without any wire.
