Electro Polishing Method

In the electro polishing method, through the apertures in the stencil a local acid rinsing is performed. For controlling removal for roughness, additionally electric voltage is applies. Thus it is possible to reproducibly improve surface quality of the aperture walls.

Our customers rely on this surface technology when they require the release characteristics of galvanically structured high-quality stencils with the precision of laser-cut stencils.
