In addition, the rise of Mini LED backlight brings new growth opportunities to packaging enterprises. Packaging enterprises are expected to become suppliers of Mini backlight modules from LED lamp bead devices. In this wave of Mini/Micro LED, China’s upstream LED epitaxial chip enterprises have become the most important participants in the global industrial chain. SAN ‘an, Huacan and other upstream chip enterprises are the core suppliers of Samsung, Apple, LG and other famous enterprises in the field of Mini/Micro, which also drives the rapid development of the domestic middle and downstream industrial chain.
The emergence of LED lights has opened a new space for the lighting field. Under the tilting and promotion of national policies, LED lights have been popularized rapidly. For a time, “high light efficiency, long service life” and other slogans appeared in the product brochures of businesses and manufacturers, and many families have replaced the new LED energy-saving lamps. However, many users report that LED lights don’t take long to dim and slowly fail. Why is that? The answer can be found from the development process of LED lamp in our country. In the late 1990s, the invention of white LED laid a solid foundation for the future development of LED lights, and because of the advantages of low heat, less power consumption and other energy saving and environmental protection quickly entered the national public places.
The silver paste of the failed LED chip was separated from the substrate, and a layer of corrosive products was attached to the silver paste surface of the separation surface, and the corrosive element Cl was found by EDS analysis. Cl will corrode the silver particles in the silver paste, affect the conductive properties of the silver paste, resulting in a decrease in the bonding strength of the silver paste, and eventually an open circuit between the substrate and the LED chip. The physical size of the LED chip itself is very small.
