Optical metal polishing flat to millionths of inch
http://www.optical-polishing.com/optical-metal-polishing.htm
Optical metal polishing flat to millionths of inch. Optical Polishing of Metals for Best Finish and Flatness. Optical metal polishing of flat surfaces can yield finishes in the 10 to 20 Angstrom Ra range depending on the alloy and the quality of the alloy. Optically superpolished fused silica wafers with 3 Angstrom Ra surface finish are being done at production level quantities. This level of surface finish is usually a requirement for critical MEMS surfaces. Go to valleydesign.com. Return to Home Page.

Laser hole and edge rounding, chamfering and blending
http://www.laserslag.com/index.htm
Laser hole and edge rounding, chamfering and blending. Deburring, Chamfering, Blending, and Rounding. Laser slag associated with laser drilled holes is unwanted raised material remaining on the top surface and inside the holes as a result of the lasering process. This laser slag, on microelectronic substrates, needs to be removed because the loose material can cause metalization adhesion problems especially in Aluminum Nitride. This process can be used to clean slag from either or both sides of lasered p...
