Manufacturing Process

The manufacturing process of SMD LED 0402 involves several steps, including wafer fabrication, die cutting, wire bonding, and packaging. Here is a brief overview of the process:

• Wafer Fabrication: The wafer is made from a high-purity gallium arsenide (GaAs) or gallium nitride (GaN) substrate. The wafer undergoes a series of processes, including epitaxy, to grow the LED layers.

• Die Cutting: The wafer is then diced into individual LED die using a laser cutting process. The die are typically round or square in shape.

• Wire Bonding: The die are then wire-bonded to a lead frame using gold or aluminum wire. The wire bonds connect the die to the leads, which will be used to connect the LED to the PCB.

• Package: The die with wire bonds are then encapsulated in a small package, which protects the die and provides electrical connections to the PCB.
