How reliable are surface roughness measurements of micro-features?: Experiences of a Round Robin test within nine 4M laboratories
2008 (English)In: 4M 2008: Proceedings of the 4th International Conference on Multi-Material Micro Manufacture / [ed] S. Dimov and W. Menz, Dunbeath: Whittles Publishing, 2008, 139-142 p.Conference paper (Refereed)
Surface roughness of tiny micro machined features is not easy to verify. The statistical variation of the surface itself can be the limiting factor that hampers tolerance verification. In this paper we have studied this effect and we also test the performance of 10 different surface profilers over a very well specified surface area. For this area 6 profilers yielded the same result within a standard deviation window of ±6%. For other areas, on top of narrow bars and in narrow and deep channels, a much larger spread in the Round Robin results were found.
