- a screen printing plate is provided which is characterized by being.
- the printing material has a larger spread width in the vicinity of the concave portion (opening force, the portion where the opening becomes narrower) in the concave / convex pattern at the opening end, and the bleeding width decreases in the vicinity of the convex portion (the portion where the opening becomes larger).
- the pattern is smooth and regular. As a result, irregularities in the shape of the print pattern due to bleeding of the printing material can be prevented, so even if the target print pattern is a fine design, it is more accurately transferred with higher transferability.
- the shape can be printed.
- the size of the opening is made smaller than the target printing pattern, so that the printing material after the printing material has blotted.
- the shape of the print pattern can be matched with the shape of the target print pattern.
- the concavo-convex pattern shape of the opening end portion of the opening portion is such that the convex portion is at a position reduced by 0 to 25 ⁇ m from the end portion of the target printing pattern. preferable. In this way, by making the convex part of the opening at a position that is reduced by 0 to 25 m from the end of the target print pattern, the shape of the print pattern after the printing material has blotted can be made more accurate. To the shape of the target print pattern.
- the height of the protrusion with respect to the recess is 5 to 25 m.
- the height force of the convex portion with respect to the concave portion is 5 to 25 / ⁇ ⁇ , so that the spread width of the printing material in the vicinity of the concave portion is more effectively increased and the blur width in the vicinity of the convex portion is reduced. Therefore, the printed pattern after printing can be made more effective and smooth.
- the uneven pattern shape at the opening end of the opening has a period of the uneven pattern of 5 to 50 m.

- the concavo-convex pattern shape of the opening end portion of the opening portion is formed by periodically forming bag-like concave portions.
- the concave / convex pattern shape is such that bag-like concave portions are periodically formed, so that it is possible to produce a portion that actively causes bleeding, and as a result, more effective bleeding occurs. Can be controlled. That is, it is possible to positively induce bleeding directly under the non-opening portion surrounded by the bag-like opening portion.
- the shape of the bag-shaped recess is circular or trapezoidal.

- the squeegee is translated by a parallel movement mechanism, and the printing material is discharged through the opening of the screen printing plate and applied to the substrate. Since the end portion has a concavo-convex pattern shape different from the target print pattern shape, the end portion has a concavo-convex pattern at the opening end portion of the opening portion. In the vicinity of the concave portion, the spread width of the printing material is increased, and in the vicinity of the convex portion, the spread width is decreased. As a result, the end portion of the print pattern has a smooth and regular shape.

- Screen printing is used in many industrial fields because of its high productivity. However, when screen printing is used to print a desired printing pattern, especially a fine design, it is opened. There is a problem that transferability is lowered due to bleeding of the printing material from the end. On the other hand, in screen printing used in the electronic industry field, for example, printing of patterns for solar cells, etc., particularly high transferability is required.
- the present inventors have conducted intensive research, and at least a screen printing plate provided with an opening for discharging a printing material for forming a desired printing pattern on a printed material in screen printing.
- the size of the opening is smaller than the target print pattern, and the opening end of the opening has an uneven pattern shape different from the target print pattern shape. This prevents irregularities in the shape of the printed pattern due to bleeding of the printing material, and even if the target printed pattern is a fine design, the pattern shape as intended can be obtained more accurately with high transferability. I found out that it can be printed.
- FIG. 1 and FIG. 2 are schematic plan views showing an example of the screen printing plate of the present invention in which the opening end of the opening has an uneven pattern shape (triangular wave).
- FIG. 9 is a schematic sectional view of an example of the screen printing apparatus of the present invention.
- the screen printing apparatus 10 using the screen printing plate 1 of the present invention includes at least a screen.
- the screen printing plate 1 is provided with the opening 2 for discharging the printing material 12 for forming the target printing pattern 4 on the substrate 11, and the size of the opening 2 is the target printing pattern.
- 4 and the opening end 3 of the opening 2 is translated on the screen printing plate 1 having a concavo-convex pattern shape different from the shape of the target printing pattern 4 and the screen printing plate 1.
- the squeegee 21 that discharges the printing material 12 through the opening 2 and applies the printing material 12 to the substrate 11 fixed on the chuck table 23, and the translation mechanism 20 that translates the squeegee 21 are provided.
- the screen printing plate 1 of the present invention is provided with an opening 2 for discharging a printing material 12 for forming a target printing pattern 4 on a substrate 11 in screen printing.
- the size of the opening 2 is smaller than that of the target print pattern 4, so that the printing material 12 can match the shape of the print pattern 5 after printing with the shape of the target print pattern 4. I'll do it.
- the concave portion in the concavo-convex pattern of the opening end 3 of the opening 2 is used during screen printing.
- the spread width of the printing material 12 increases, and in the vicinity of the convex portion 6, the spread width decreases, so that the printed pattern 5 after printing has a smooth and regular shape. This is because if the end of the opening has a similar shape as the target pattern shape as before, if the end is a straight line, the printing material bleeds irregularly and cannot be controlled. This is in contrast to the inability to form the desired printed pattern.
- the printed pattern after printing is blurred. Due to the phenomenon, it becomes a gentle pattern 5 with the same period as the triangular wave.
- the printed pattern 5 after printing expands from the opening due to bleeding.
- the shape of the printed pattern 5 after printing is a shape in which the corners of the triangular wave of the boundary line are dulled (rounded), and the period of the shape of the edge coincides with the period of the triangular wave of the boundary line. In other words, it does not become an irregular pattern like 5a in Fig. 3.
- FIG. 1 In screen printing, the printing material 12 is pushed out from the opening 2 by the sliding motion of the squeegee 21 and comes into contact with the surface of the substrate 11. Ideally, it is desirable that the contact surface between the printing material 12 and the substrate 11 is limited to a position directly below the opening 2, but a certain pressure is applied to the printing material 12 to start from the opening 2 of the screen printing plate 1. Due to the printing principle of extruding, it is inevitable that the printing material 12 oozes into the space between the non-opening 1B of the screen printing plate and the substrate 11.
- the volume of the printing material 12 that spreads from the opening end 3 under the non-opening portion 1B is the same per unit length of the opening end 3. Further, when the printing material 12 bleeds from the opening 2 under the non-opening 1B, the printing material 12 bleeds in the direction perpendicular to the opening end 3 as indicated by the arrow in FIG. As a result, the ideal spread width should be equidistant from the open end 3 and should be as shown by the alternate long and short dash line in the figure.
- the density of the arrows 8 is different from that of the other straight portions in the vicinity of the convex portion 6 of the opening 2 and in the vicinity of the concave portion 7 of the opening 2. Further, the density of the arrows 8 is different between the periphery of the convex portion 6 of the opening 2 and the periphery of the concave portion 7 of the opening 2.
- the volume of the printing material 12 that oozes out is small. The volume of the printing material 12 that oozes out is large in the area surrounded by.
- the spreading width force S decreases immediately below the recess of the non-opening portion 1B (around the tip of the convex portion 6 of the opening 2), and immediately below the convex portion of the non-opening portion 1B (the recess 7 of the opening 2). In the area surrounded by), the spread width increases. Then, the end surface of the printing material 12 (broken line in the figure) has a shape that cancels out the irregularities of the opening 2 and the corners become blunt (round).
- Printing after printing is performed by utilizing the phenomenon that the amplitude of the printed pattern 5 after printing becomes smaller than the amplitude of the opening end 3 of the opening 2 and the non-opening 1B due to the phenomenon that the corners are rounded. It is possible to control the bleeding shape by bringing the shape of pattern 5 closer to the shape of the desired printed pattern 4. It is the principle of the present invention.
- a periodic wave such as a triangular wave having a force substantially the same as the size of bleeding under the printing conditions originally used and a smaller size may be produced in the opening 2.
- the period and amplitude of the periodic wave at the opening end 3 are made sufficiently larger than the size of the original bleeding, the bleeding in the straight line portion of the periodic wave cannot be ignored.
- a concavo-convex pattern is produced with an amplitude smaller than the spread width in the printing conditions to be used.
- the unevenness of the shape of the printed pattern 5 after printing is reduced.
- the bleeding is performed so that the center of the amplitude follows the shape of the desired print pattern 4.
- An uneven pattern is produced with an amplitude smaller than the width.
- the concavo-convex pattern shape of the opening end 3 of the opening 2 is set so that the protrusion 6 is reduced by 0 to 25 m from the end of the target print pattern 4.
- the shape of the printed pattern 5 after printing after the printing material 12 has spread can be more accurately matched with the shape of the intended printed pattern 4.
- the uneven pattern shape of the opening end 3 of the opening 2 is a height force of the protrusion 6 with respect to the recess 7 of 5 to 25 / ⁇ ⁇ , printing in the vicinity of the recess 7 is more effectively performed. Since the spread width of the material 12 can be increased and the spread width near the convex portion 6 can be reduced, the printed pattern 5 after printing is made more effective and smooth and matches the target pattern 4. be able to.
- the uneven pattern shape of the opening end 3 of the opening 2 is such that the period of the uneven pattern is 5 to 50 / ⁇ ⁇ . Since the spread width of the printing material 1 2 can be increased and the spread width near the convex portion 6 can be reduced, the printed pattern 5 after printing is made more effective and smooth and regular. be able to. Note that the regular printed pattern shape has a period that coincides with the concavo-convex pattern of the opening end 3. Therefore, the shape of the pattern 5 after printing can be freely controlled.
- the width of the recess 7 is 5 to 25 / zm. As a result, the spread width of the printing material 12 in the vicinity of the recess 7 can be increased more effectively, and the printed pattern 5 after printing can be made more effective and smooth. Can do.
- the uneven pattern shape of the opening end 3 of the opening 2 is at least one of a triangular wave, a rectangular wave, a sine wave, or a combination of these shapes. It is possible to form a concavo-convex pattern having a simple and accurate synchrony, and it is easy to design and produce the concavo-convex pattern, thereby reducing the manufacturing cost. In addition, with such a pattern, the printing material easily bleeds in the recesses, and the pattern after printing is easily flattened.
- the concave-convex pattern shape of the opening end 3 of the opening 2 is formed by periodically forming bag-like concave portions 7B.
