Manufacturing Process of Infrared LED SMD
The manufacturing process of infrared LED SMD involves several steps, including epitaxy, wafer slicing, dicing, bonding, and packaging. Here is a brief overview of the process: 1. Epitaxy: The first step in the manufacturing process is epitaxy, where a thin layer of semiconductor material is deposited on a substrate. This layer acts as the active region of the LED. 2. Wafer Slicing: After epitaxy, the wafer is sliced into thin circular disks called wafers. These wafers are then polished to achieve a smooth surface. 3. Dicing: The wafers are then diced into individual LED chips using a dicing saw. The dicing process ensures that each chip has the desired size and shape. 4. Bonding: The LED chips are bonded to a substrate using a metal or dielectric bond. This step ensures electrical contact between the chip and the substrate. 5. Packaging: Finally, the bonded LED chips are packaged using a plastic or ceramic encapsulant. This step protects the LED chips from environmental factors and ensures long-term reliability.Market Trends and Future Outlook
