Abstract
Controlled depositing of a printing material on a substrate is provided. A stencil is disposed adjacent to the substrate. The stencil includes a number of apertures to allow printing material to pass therethrough. Printing material is deposited onto and spread across the stencil with a squeegee blade. To increase the volume of printing material over a set of selected apertures, the squeegee blade includes a printing edge having a profile feature.
Claims18
A method for depositing a printing material on a substrate, comprising:
- depositing the printing material onto a stencil defining a first aperture and a different size second aperture adjacent to the substrate;
- and
- spreading the printing material across the stencil with a squeegee blade operably defining a non-constant spatial disposition from a surface of the stencil facing the squeegee blade, the non-constant spatial disposition formed by a linear edge of the squeegee blade at a predetermined spatial disposition that is sized in relation to the size of the first aperture and operably aligned with the first aperture and a profile feature of the squeegee blade contiguous with the linear edge at a different predetermined spatial disposition that is sized in relation to the size of the second aperture and operably aligned with the second aperture, so that the amount of the printing material operably delivered to the surface of the stencil facing the squeegee blade varies in direct relation to the non-constant spatial disposition between the squeegee blade and the surface of the stencil facing the squeegee blade.
A printing device for depositing a printing material on a substrate, comprising a squeegee blade for spreading the printing material onto a stencil defining a first aperture and a different size second aperture adjacent to the substrate, the squeegee blade operably defining a non-constant spatial disposition from a surface of the stencil facing the squeegee blade, the non-constant spatial disposition formed by a linear edge of the squeegee blade at a predetermined spatial disposition that is sized in relation to the size of the first aperture and operably aligned with the first aperture and a profile feature of the squeegee blade contiguous with the linear edge at a different predetermined spatial disposition that is sized in relation to the size of the second aperture and operably aligned with the second aperture, to operably spread the printing material onto the surface of the stencil facing the squeegee blade in different amounts that vary in direct relation to the non-constant spatial disposition between the squeegee blade and the surface of the stencil facing the squeegee blade.
