With the rapid development of technology, infrared LED has become an indispensable part of our daily lives. As a result, the infrared LED factory has emerged as a crucial industry. This article aims to provide an in-depth introduction to the infrared LED factory, covering its history, production process, applications, and future prospects.

History of Infrared LED Factory

The history of infrared LED can be traced back to the 1960s when scientists discovered that gallium arsenide (GaAs) could emit infrared light when stimulated by electricity. Since then, the infrared LED industry has experienced rapid development. In the 1970s, infrared LED technology was mainly used in military fields. However, with the advancement of technology, its applications have gradually expanded to consumer electronics, automotive, medical, and other fields.

Production Process of Infrared LED Factory

The production process of an infrared LED factory generally includes the following steps: 1. Material preparation: The main materials for infrared LED production are gallium arsenide (GaAs), gallium nitride (GaN), and indium phosphide (InP). These materials are processed into ingots through melting and crystallization. 2. Ingot slicing: The ingots are sliced into thin wafers using a diamond saw. 3. Wafer epitaxy: The wafer is coated with a layer of gallium arsenide (GaAs) or gallium nitride (GaN) through epitaxy technology. 4. Structure growth: The epitaxial wafer is further processed to form the core layer, cladding layer, and contact layer of the infrared LED. 5. Photoelectric device fabrication: The wafer is diced into individual chips, and the chip is then processed to form the lead frame, pad, and wire bonding. 6. Packaging: The chip is mounted on the lead frame and encapsulated with a package material, such as epoxy or silicone.
