Abstract:
A double printing screen stencil includes a first screen stencil and a second screen stencil. The first screen stencil pattern includes equally spaced fingers. A plurality of bottom electrodes are arranged at the position of the busbar intersecting with the fingers. The first screen stencil pattern further includes at least two aligning points. The second screen stencil pattern includes equally spaced fingers, busbars intersecting with the fingers, aligning points corresponding to the aligning points in the first screen stencil pattern. The fingers are corresponding to those of the first screen stencil and the spacing of the fingers is the same as that of the first screen stencil. When the screen stencil is used in printing, the bottom electrodes are printed at the position of the busbar while the fingers are printed during the primary printing, so as to increase the height of busbar during, the secondary printing.
