Electro-polishing method

With the electro-polishing method, local acid rinsing is performed through the apertures in the stencil. An electric voltage is also applied to control roughness removal. This makes it possible to reproducibly improve the surface quality of the aperture walls.


Our customers rely on the electro-polishing method when they are looking for the release characteristics of high-quality galvanically structured stencils combined with the precision of laser-cut stencils.
