Definition and Classification of SMD LED Chip

SMD LED chip, short for Surface Mount LED chip, refers to a type of LED chip that can be directly mounted on the surface of the circuit board. It has the advantages of small size, light weight, and low power consumption. According to the light color, SMD LED chips can be divided into red, green, blue, yellow, and other colors. According to the luminous intensity, they can be divided into high brightness, medium brightness, and low brightness.

Production Process of SMD LED Chip

The production process of SMD LED chip generally includes the following steps:

1. Crystal Growth: The crystal material, typically gallium nitride (GaN), is grown by the epitaxy method.
2. Crystal Cutting: The crystal is cut into a certain thickness and shape, usually a wafer.
3. Layering: Various layers are grown on the wafer surface by epitaxy, including the p-type layer, n-type layer, and LED chip layer.
4. Etching: The wafer is etched to form a semiconductor chip with a certain thickness and shape.
5. Mounting: The semiconductor chip is mounted on a metal substrate and connected to the lead frame.
6. Coating: The surface of the LED chip is coated with a phosphor material to convert the light emitted by the LED chip into the desired color.
7. Testing: The LED chip is tested for quality, including luminous intensity, color temperature, and life span.
8. Packaging: The LED chip is packaged and shipped.
