Webinar Overview

Surface texture affects performance and reliability of a wide range of products ranging from automobile components, consumer electronics, photovoltaics to space applications. Accurate characterization of surface texture is critical for manufacturing process control and understanding the mechanism of product failure. Roughness is the most commonly used parameter to characterize surface texture. Thus, understanding of surface roughness measurement and analysis will help to optimize manufacturing process and improve product quality.

This webinar is designed to give the audience an overview of surface roughness measurements and analysis, with a focus on two widely employed methods of surface roughness measurements (1) Contact method using stylus and (2) Non-contact method using optical interferometric principle.

In this webinar, we will go through available methods of surface roughness measurement, followed by detailed discussion on line profile roughness and areal roughness measurement using stylus and optical interferometry respectively. Commonly asked questions about distinction/overlap in the line profile vs areal roughness analysis would also be included.
