Diamond Back Grinding Wheel For Sapphire
Diamond Back Milling Wheel For Sapphire
- Resin Type
- Vitrified Type
- Metal Type
Diamond back grinding wheel for sapphire is a tool used to reduce the thickness of sapphire substrates, mainly used to improve the heat dissipation performance of devices. After the electrode preparation process is completed, the sapphire substrate usually needs to be thinned on the back to improve the heat dissipation performance.
Diamond back grinding wheel for sapphire is used for back thinning grinding of sapphire substrates of various sizes, and can be suitable for equipment such as NTS, DISCO, ACCRETECH,TECHDI. According to the requirements, design the shape of diamond grinding wheel with high grinding efficiency and long life.
Application of Diamond Back Grinding Wheel for sapphire:
It is used for silicon on sapphire epitaxial wafers, SiC epitaxial wafers, Si epotaxial wafers, Zirconia ,etc.
Workpiece materials: synthetic sapphire, SiC, monocrystalline silicon, etc.
It can be matched with machine tool manufactured by companies such as DISCO, OKAMOTO, TSK, and STRABUGH.
About Sapphire Back Thinning Grinding
The main reason for sapphire back thinning is to improve heat dissipation and processing performance. Sapphire is widely used in fields such as lighting, and semiconductor substrates, especially in substrate materials for gallium nitride epitaxial growth. Sapphire back thinning is crucial for improving the heat dissipation performance.
Reasons For Sapphire Thinning Include:
Improving heat dissipation performance: In semiconductor devices, reducing the thickness of sapphire substrates can significantly improve heat dissipation efficiency, thereby reducing the heat and extending the life.
Improving processing performance: By thinning the sapphire substrate, the thickness of the material can be reduced, making it easier for subsequent processing and handling, thereby improving production efficiency and product quality.
