The objective of the grinding stage is to prepare the upper and lower surfaces of the sample parallel and with a fine finish. Typically, a mirror finish is desired, which corresponds to a surface roughness of Ra better than 0.1 µm .For route A the sample is ground to approx. 100 µm, which is the optimum thickness for dimple grinding.
