Description
The surface quality of drawn wire can be important. This is especially true for magnet wire, where irregular wire surface could cause the enamel to rupture in service. Evaluation of a wire surface using the scanning electron microscope and combined with profilometry data, yields in- depth analysis of the surface. Such an analysis is vital in determining and eliminating the source of surface imperfections. A simple optical microscope can be useful for in-plant auditing of the surface.
