Potomac Photonics offers a broad range of value-efficient and highly repeatable laser micromachining capabilities which are accessible for functions ranging from prototyping by means of manufacturing manufacturing. Floor micromachining builds microstructures by deposition disambiguation needed and etching totally different structural layers over a substrate 1 This is different from Bulk micromachining , through which a silicon substrate wafer is selectively etched to provide structures.

This effect, along with the necessity for a minimal scarf thickness required for its elimination, the heterogeneities of the material to be machined, the presence of burrs of a big dimension compared to that of the machining features (all of which, typically, are of virtually zero importance in standard milling), have significant significance for performances in the micromilling process.

Typical applications are cutting filigree constructions like stents for the medical trade or reducing the smallest components out of chrome steel, nonferrous metallic and ceramic for the …
