0805 bi color LED, also known as the 0805 dual-color LED, is a popular type of surface mount LED with a diameter of 0.8mm and a thickness of 0.5mm. It is widely used in various electronic products, such as smart phones, computers, digital cameras, and home appliances. In this article, we will introduce the industry of 0805 bi color LED, including its production process, market application, and future development trends.

Production Process of 0805 Bi Color LED

The production process of 0805 bi color LED mainly includes the following steps: 1. Material preparation: The raw materials used in the production of 0805 bi color LED mainly include gallium nitride (GaN), indium gallium nitride (InGaN), and silver paste. These materials need to be processed and purified before use. 2. Crystal growth: The gallium nitride crystal is grown by the hydride vapor phase epitaxy (HVPE) method, and the indium gallium nitride crystal is grown by the metal organic chemical vapor deposition (MOCVD) method. The crystal quality directly affects the performance of the LED. 3. Crystal slicing: The crystal is sliced into a thin wafer by a wire saw. The thickness of the wafer is usually about 0.1mm. 4. Dicing: The wafer is diced into individual LED chips by a dicing machine. The size of the 0805 bi color LED chip is 0.8mm x 0.5mm. 5. Chip bonding: The LED chip is bonded to a lead frame by a silver paste. The lead frame is usually made of nickel or copper. 6. Chip encapsulation: The LED chip is encapsulated with epoxy resin to protect the chip and improve the heat dissipation performance. 7. Wire bonding: The wire bonding machine bonds the lead frame to the LED chip. The wire is usually made of gold or silver. 8. Testing: The finished 0805 bi color LED is tested for its electrical and optical performance. 9. Packaging: The tested 0805 bi color LED is packaged into a standard package for use in electronic products.
