WebA number of standard parameters are used to describe surface roughness of engineered surfaces. Average roughness (R a) is the average of the individual heights (asperities) and depths from the arithmetic mean elevation of the profile. 1 1 0 0 1 ( , ) m n a k l k l R Z x y mn µ − − = = = −∑∑ (20) Where, 1 1 0 0 1 ( , ) m n k l k l Z x ... WebSU-8 surfaces are dominated with peaks and positive Rsk and Rku. The variation of the sidewall roughness can be observed from Figure 7, where Rq and Rp-p of silicon sidewall varies considerably. In contrast, SU-8 exhibits more consistent Rq and Rp-p values. Both SU-8 and silicon show variance in Rsk and Rku values. newsxpress ocean grove

"WebContact, or stylus-based, surface profilometers measure surface texture by dragging a sharp, pointed tool across the surface. Height variations of the tip are recorded and then used to form a texture profile. Roughness and waviness are also calculated from the surface profile data. Non-contact surface profilometers measure the surface texture ... " - Rku roughness

WebThe Rku parameter characterises the spread of the height distribution. A surface with a Gaussian height distribution has a kurtosis value of three. Unlike the Rsk parameter, kurtosis can not only detect whether the profile spikes are evenly distributed but also provides a measure of the spikiness of the area. A spiky surface will have a high kurtosis value and a …
