Manufacturing Process of SMD LED 0805

The manufacturing process of SMD LED 0805 involves several steps, including epitaxy, wafer slicing, dicing, bonding, and packaging. Here’s a brief overview of each step:

1. Epitaxy: The process starts with epitaxy, where a thin layer of semiconductor material is deposited on a substrate. This layer serves as the active region of the LED, emitting light when an electric current is applied.

2. Wafer Slicing: The epitaxial wafer is then sliced into thin circular discs called wafers. These wafers are the building blocks for individual LEDs.

3. Dicing: The wafers are diced into individual LED chips using a diamond saw or laser cutting technique. This process creates precise and uniform LED chips with the desired dimensions.

4. Bonding: The LED chips are then bonded to a lead frame using a silver paste. This paste acts as a conductive adhesive, ensuring a reliable electrical connection between the chip and the lead frame.

5. Packaging: Finally, the bonded LED chips are encapsulated in a transparent or colored resin to protect them from environmental factors and improve their light extraction efficiency. The packaged LEDs are then tested and sorted based on their brightness and color.
