The "0805" refers to the industry-standard metric package size, which is widely adopted in the electronics industry.
Design and Manufacturing
The design of the 0805 SMD LED involves encapsulating a semiconductor chip within a small, flat package. The semiconductor chip is typically made of gallium nitride (GaN), gallium arsenide (GaAs), or silicon carbide (SiC), which are materials known for their high efficiency and ability to emit light at various wavelengths. The manufacturing process involves several steps, including chip fabrication, wire bonding, and encapsulation.
During chip fabrication, the semiconductor material is grown and then patterned to create the diode structure. Wire bonding is the process of connecting the semiconductor chip to the leads of the LED package, ensuring a reliable electrical connection. Finally, encapsulation involves sealing the chip and leads within a transparent or colored epoxy package, which protects the internal components and enhances the light output.
