This is where one of the biggest problems begins. a "grinder" style sharpening machine will absolutely ruin the Japanese style shear by destroying the convex edge and replacing it with a bevel "concave" edge. A convex grinding wheel can only make a concave edge on the shear blade. Don't let anyone try to tell you different.

Jan 25, 2016· Ever wonder how silicon wafers get so thin? What are the processes involved in polishing a coarse wafer into a usable and high-grade silicon wafer? Find out in the video! #silicon #siliconwafer.
TAIKO is a DISCO developed wafer back grinding method. By enabling an outer support ring to the wafer (the TAIKO ring, Japanese for drum), back grinding is performed on the inner circular area of the wafer, while leaving an edge of a few millimeters unprocessed. .
Semiconductor Wafer Edge Analysis/6 Figure 3 shows an example of an edge measurement of a thin bonded wafer. This demonstrates defects leading up to and within the transition region of a rounded wafer edge. The upper plot shows the roughness calculated with a high pass filter (cutoff filter) of 250 µm over a distance of 6,000 µm.
What is a Silicon Wafer? Silicon is a gray, brittle, tetravalent, chemical element. It makes up 27.8% of the earth's crust and next to oxygen, it is the most abundant element in nature. Some of the most common materials that contain silicon are quartz, agate, flint, and common beach sand, among others.
Newly-developed grinding unit enhances the rotative precision of the spindle, and improves the surface roughness. The non-contact measuring method achieves the stable alignment. Performs the non-contact measuring of the pre-processed wafer thickness at multiple points, the diameter and notch depth of the post-processed wafer.
