PROBLEM TO BE SOLVED: To simultaneously mask-print specified patterns atop the respective to-be-printed planes of a circuit substrate having a level difference.SOLUTION: Mask printing is executed by using a mask formed to bear a three-dimensional shape and a squeegee contacted with and mobilized atop the mask reference plane. A mask-printing device 1 uses a substrate 10 having a level difference and a mask 20 possessing a first mask plane 21 and a second mask plane 22 according with the shape of the substrate 10, above all the level difference thereof. A recessed portion 25 is formed on the mask 20, whereas the second mask plane is formed within the recessed portion 25. Moreover, pattern holes 30 embodying a specified shape are formed on the first mask plane and second mask plane. A printing operation is executed by using this mask in a state where a printing target and the mask are being set in opposition to one another. When the squeegee is mobilized, a paste can be transferred onto the substrate 10 in a specified shape through the pattern holes 30 formed within the recessed portion 25 of the mask and can be printed simultaneously onto the substrate 10 through the pattern holes 30 formed on the reference plane 29. |
