Production Process

The production process of SMD LED diodes bulk involves several key steps: 1. Material Selection: High-quality gallium nitride (GaN) or silicon carbide (SiC) substrates are chosen for their excellent thermal conductivity and electrical properties. 2. Epitaxial Growth: Thin layers of LED materials, such as GaN or InGaN, are grown on the substrates using molecular beam epitaxy (MBE) or metal organic chemical vapor deposition (MOCVD) techniques. 3. Doping and Annealing: The epitaxial layers are doped with impurities to create p-n junctions, which emit light when an electric current is applied. Annealing processes are used to improve the crystal quality and reduce defects. 4. Structural Fabrication: The doped layers are patterned and etched to form the LED structure, including the p-type and n-type regions, as well as the metal contact pads. 5. Bonding and Packaging: The LED chips are then bonded to metal leads or wire bonds, followed by encapsulation with a protective material to prevent moisture and dust from entering the device.
