Description
Summary:One of the ways of increasing accuracy of printed electronics elements produced with the use of stencil screen printing is the use of doctor rollers with a resilient cellular packing. The amount of paste in cells is regulated by a metering doctor blade and depends on the hydrodynamic pressure in paste. This paper presents a method of determining the thickness of the paste layer with a viscosity of 400 Pa·s on a print. The experiments showed that the pressure in the layer of paste in front of a moving doctor roller is 30000-130000 Pa. For the preliminary gap between the doctor blade and doctor roller of 0-0.3 mm, thickness of the paste layer on the print is 8-12.9 µm.
