Manufacturing Process

The manufacturing process of LED 5mm green involves several steps: 1. Material Preparation: High-purity gallium nitride (GaN) is typically used as the semiconductor material for green LEDs. This material is doped with indium and gallium to achieve the desired green emission. 2. Wafer Growth: The semiconductor material is grown on a sapphire or silicon substrate using a method called epitaxy, which involves depositing layers of the semiconductor material onto the substrate. 3. Laser Trimming: After the epitaxial growth, the wafer is laser-trimmed to create individual LED dies with the desired dimensions. 4. Dicing: The wafer is then diced into individual LED dies, which are the individual components that will be mounted onto the circuit board. 5. Bonding: The LED dies are bonded to the circuit board using gold or silver wire bonds to create electrical connections. 6. Encapsulation: The LED dies are encapsulated in a transparent or diffused epoxy material to protect them and provide a smooth, consistent light output. 7. Testing: Finally, the LEDs are tested for electrical performance and color consistency before being packaged and shipped.
