Color Mixing: The dual-color feature of the 0807 bi-color LED allows for the creation of various colors by mixing red and green light.

Manufacturing Process of 0807 Bi-color LED

The manufacturing process of the 0807 bi-color LED involves several steps: 1. Material Preparation: High-purity gallium nitride (GaN) and indium gallium nitride (InGaN) are used as the active layer materials. These materials are mixed and sintered to form a single crystal. 2. Epitaxy Growth: The single crystal is then subjected to epitaxy growth, where a thin layer of GaN or InGaN is deposited on a sapphire or silicon substrate. 3. Doping: Dopants are introduced to the epitaxial layer to create p-type and n-type regions, which facilitate the flow of electrons and holes. 4. Milling: The epitaxial wafer is milled into thin wafers with a thickness of approximately 50 micrometers. 5. Scribing and Dicing: The wafer is scribed and diced into individual LED chips, which are then mounted on a lead frame. 6. Bonding: The LED chips are bonded to the lead frame using a silver paste, and the lead frame is then trimmed and formed into the desired shape. 7. Encapsulation: The LED chips are encapsulated with a clear or colored epoxy resin to protect them from environmental factors. 8. Testing: The final step involves testing the LED chips for electrical and optical performance to ensure they meet the required specifications.
