name: diamond backgrinding wheel
application: silicon wafer
Details
Introduction of back grinding wheels:
Diamond back grinding wheels are used for silicon wafer grinding. our advanced technology makes back grinding wheel possible to grind all types of semiconductor wafers with less subsurface damage.
During grinding, the grinding wheel and the wafer rotate about their own rotation axes simultaneously, and the wheel is fed towards the wafer along its axis. The rotation axis for the grinding wheel is offset by a distance of the wheel radius relative to the rotation axis for the wafer.

Applications of back grinding wheels:
Back thinning, rough grinding and fine grinding of silicon wafer.
Workpiece processed include silicon wafer of discrete devices, integrated chips (IC) and virgin etc.
Advantages of back grinding wheels:
good Self-dressing ability, Long life and low prices.
high heat conductivity, high wear resistance, and low coefficient.
it is highly desirable that grinding wheels generate only very low damage to ground wafers.
Applicable grinding machine:
The back grinding wheels can be used for the Japanese ,German, American, Korean and other grinders . Such as Okamoto , Disco, Strasbaugh and others grinding machine.
The Features of Back-side-Grinding-wheels:
1)Various directions of producing chemicals or metallurgical products. Provide with high efficiency of grinding and durable lifetime.
2) Stable manufactures technics. Provide with fine roughness of wafer surface.
3) Back Grinding wheel is the precision processing tool used in the process to grind unnecessary wafer back side and make the wafer back side with excellent backside roughness and uniform thickness, high technology is required to minimize wafer defect whose material is expensive and easy to be broken.
