But as the components get smaller and smaller at some point the apertures become so small that the paste won\u2019t transfer through the stencil anymore. The paste just gets \u201cstuck\u201d in the aperture. In that case you either lower the stencil thickness to improve the printing (if applicable) or make the apertures smoother so that it\u2019s easier for the paste to release, i.e. the stencil undergoes a process of <strong>Electrochemical polishing.<\/strong><\/p><p>The improvement of the quality of the printing is achieved by reducing the capillary forces that the apertures exert on the paste.
