Application and processing method of sapphire crystal

                                                          Application and processing method of sapphire crystal

Sapphire crystal refers to non red aluminum oxide, which has the characteristics of high sound speed, high temperature resistance, corrosion resistance, high hardness, high light transmittance, and high melting point (2045 ℃). It is a very difficult material to process, so it is often used as the material of photoelectric components. Sapphire crystal is an extremely important basic material for modern industry, especially for microelectronics and optoelectronics industry. It is an upstream product in the LED new light source industry chain. Sapphire crystal is widely used in high-tech fields of semiconductor, chemical industry, aviation, aerospace, national defense and other industries, and has great social and economic benefits.

Sapphire crystal and three generation semiconductor materials, such as monocrystalline silicon, gallium arsenide, gallium nitride and silicon carbide, are different in quality but belong to the same kind (crystal). Many crystals support, compete and entangle each other.

Sapphire crystal growth and slicing project is the core link of the LED industry chain. Its products are one of the important upstream raw materials of the LED industry. LED is the abbreviation of light emitting diode. It has the characteristics of high luminous efficiency, environmental protection, long life, small size, etc. It is now the world Zui's advanced lighting technology in the world. Sapphire chip has become the key material for making white/blue/green LED, and has been in short supply in LED application field.

In the field of LED production and manufacturing, there are only two kinds of substrates that can be used for commercialization, namely sapphire crystal and silicon carbide substrate, but silicon carbide substrate It's expensive. Therefore, 80% of the global LED enterprises use sapphire as the main raw material for manufacturing LED products. It is difficult to process sapphire because of its high hardness; In particular, the slicing process is more difficult. Ordinary sapphire slicers will have many problems in the working process, which will cause the product quality to decline and even cause rejection.

The growth and slicing of sapphire crystal are different in technology. They are often similar to the production and slicing of monocrystalline silicon, and the construction of sapphire crystal projects conforms to national industrial policies The products encouraged by China have good market prospects, which can promote the development of energy-saving products in China and play a positive role in building a conservation oriented society in China. Yibo CNC wire cutting machine adopts diamond sand wire cutting, which can be used for sapphire slicing. The handle cao is simple to operate, and the wire cutting is stable, which improves the processing efficiency of the slicer. Automatic inspection is set on the outer side of the guide wheel The broken wire protection device of the measuring diamond wire ensures the smoothness of the whole slicing process and the high quality of the finished product, thereby reducing the production cost and increasing the economic benefits.
