Abstract:
A stencil for the deposit and apportioning of more or less thick layers, based on points or in the form of points, of a viscous product on a substrate by passing a scraper over the stencil to bring the stencil into close contact with the substrate in the place where the scraper exerts a linear pressure, the stencil constructed of a solid and uniformly thick sheet of a synthetic material with holes bored therethrough, wherein:the sheet thickness is determined according to the greatest height of deposit to be made on the substrate; andthe sheet has different boring diameters sized according to the height of the different deposits of the viscous product to be made and the thickness of the sheet, whereby the viscous product proportions deposited and the deposit heights obtained by a passage of the scraper are different.
