Manufacturing Process

The manufacturing process of the LED SMD 3535 3V 2W involves several steps, including wafer slicing, epitaxy, lapping, dicing, bonding, and encapsulation. Here is a brief overview of each step: 1. Wafer Slicing: The process begins with slicing a single crystal ingot into thin slices called wafers. These wafers serve as the base for growing the LED structure. 2. Epitaxy: The wafer is then placed in a vacuum chamber where epitaxial growth occurs. This process involves depositing thin layers of semiconductor materials, such as gallium nitride (GaN), onto the wafer surface to create the LED structure. 3. Lapping: After epitaxy, the wafer is lapped to achieve a flat and smooth surface. This step is crucial for the uniformity of the LED chips. 4. Dicing: The lapped wafer is then diced into individual LED chips using a diamond saw. The size of the chips is determined by the specific package requirements. 5. Bonding: The LED chips are bonded to a substrate using a silver paste. This paste acts as a conductive material that connects the chip to the external circuit. 6. Encapsulation: Finally, the bonded LED chips are encapsulated with a transparent material, such as epoxy or silicone, to protect them from environmental factors and enhance their heat dissipation.
