Major Applications of Silicon Carbide. There are many uses of Silicon Carbide in different industries. Its physical hardness makes it ideal to be used in abrasive machining processes like grinding, honing, sand blasting and water jet cutting.
Small wheels of 25mm diameter cost up to 10 for conventional abrasive and for diamond up to 200.; Large wheel of 500mm diameter and 250mm width, the cost is about 8000 to 20000.; Life of Grinding Wheel. When a grinding wheel is applied to the workpiece, the sharp edges of the abrasive grains which are cutting, will, in the end, lose their cutting effect and become dull.
The chuck table is a slightly conical shape so that the contact between the workpiece and grinding wheel is only half of a circle throughout the process. Saw marks can be observed on the ground surface, and the surface roughness depends on the grit size of the grinding wheel. ... (SemiAutomatic Equipment for Grinding Wheels) ... Silicon (Si ...

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and highdensity packaging of integrated circuits (IC).. ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum .
The back grinding process involves using a diamondresin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemicalmechanical processes, and is used to remove the bulk of substrate material prior to final finish grind, polish or ...
