An edge up on plasma cut quality - The Fabricator

Tuned gas flow and gas choices set the edge quality bar higher. There's something about a high-precision plasma-cut edge. It's shiny, almost glassy, and the cut geometry keeps getting more precise—with minimal edge rounding and washout, perfectly square or close to it. Mechanized precision plasma cutting has come a long way.

Grinding and Polishing Guide | Buehler

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...

Semiconductor Wafer Edge Analysis

Unpolished edges typically exhibit a surface pattern formed from a grinding process. Surface peaks will touch carrier walls, while valleys will trap particles and impurities. These particles can then propagate to the wafer surface and increase the risk of wafer chipping. Also, deep wells in the edge can be a location site for phosphorus during ...
