Description

  The present invention relates to a screen printing plate, and more particularly to a screen printing plate used for forming an electrode of an electronic component.

  Conventionally, in order to increase the strength of a mesh used in a screen printing plate, a honeycomb structured mesh in which a plurality of through holes having hexagonal openings are formed in a metal plate is used.

  When such a honeycomb structured mesh is arranged in a substantially rectangular region, the holes arranged in the peripheral mesh portion of the substantially rectangular region are polygonal holes that are partly cut out of a hexagon, and the polygonal holes Is different from the hexagonal hole in opening area. Therefore, in Patent Document 1, as shown in FIG. 10, polygonal holes 112 and 113 located on opposite sides of an X × Y rectangular region 110 in which a hexagonal hole 111 is formed at the center are lined up. There has been proposed a method in which paste is uniformly applied by making a symmetrical shape and making the opening area of the polygonal hole 113 located on both sides in the lateral direction the same as that of the hexagonal hole 111.

JP 2010-23253 A

  However, also in this case, on both sides in the longitudinal direction, hexagonal holes and polygonal holes 112 having different opening areas are alternately arranged with hexagonal holes. For this reason, the paste cannot be applied uniformly on both sides in the vertical direction, which causes blurring and rubbing of the outline of the printed figure.

  In view of such circumstances, the present invention is intended to provide a screen printing plate capable of performing good printing without blurring or rubbing on the outline of a printed figure.

  In order to solve the above problems, the present invention provides a screen printing plate configured as follows.

The screen printing plate comprises: (a) a support layer in which a rectangular opening penetrating between main surfaces is formed; and (b) one of the main surfaces of the support layer is bonded to the opening of the support layer. And a mesh layer having opposing rectangular figure forming regions. The graphic forming area includes a peripheral mesh area extending along at least one side of the graphic forming area and a rectangular central mesh area adjacent to the peripheral mesh area. In the central mesh region, (i) a plurality of first through holes having the same size and shape, which are hexagonal openings and arranged in a honeycomb structure at intervals, and (ii) the first A plurality of second through holes having an opening having a shape different from that of the opening of the first through hole, and at least one side of the opening being along the side of the central mesh region A hole is formed. In the peripheral mesh area, (iii) for each side of the graphic forming area along the peripheral mesh area, the opening of the first and second through holes is arranged along the side of the graphic forming area. A plurality of third through holes having smaller openings are formed at a smaller pitch than the first and second through holes .

  In the above-described configuration, the paste that has permeated from the through hole of the mesh layer to the opening portion side of the support layer is applied to the printing material, thereby forming a printed figure. The outline of the printed figure is formed by the paste that has passed through the third through hole in the peripheral mesh region. In the peripheral mesh area, the openings of the third through holes are arranged along the sides of the figure forming area, so that the paste that has passed through the third through holes is distributed substantially uniformly on the substrate to be printed. Can be formed substantially uniformly, and good printing can be performed without blurring or rubbing on the outline of the printed figure corresponding to the side of the figure forming area.

  It should be noted that the third through-hole may have the same size or shape, and the same interval may be used for each side of the figure forming region along the peripheral mesh region.

  In a preferred embodiment, the center mesh region is asymmetric with respect to a center line parallel to a pair of sides of the figure forming region and asymmetric with respect to another center line parallel to another pair of sides of the figure forming region. The first and second through holes are formed. The third through hole is formed in the peripheral mesh region along at least one of the pair of sides of the graphic forming region and at least one of the other pair of sides of the graphic forming region.

  In this case, the center mesh region is asymmetric with respect to a center line parallel to the pair of sides of the graphic forming region and asymmetric with respect to another center line parallel to the other pair of sides of the graphic forming region. Therefore, as it is, the aperture ratio of the portion along at least one of the pair of sides of the graphic forming region and the aperture ratio of the portion along at least one of the other pair of sides of the graphic forming region are Can not be uniform. Therefore, a third through hole is formed along at least one of the pair of sides of the figure forming area and at least one of the other pair of sides of the figure forming area. As a result, the aperture ratio can be made uniform, and good printing without blurring or rubbing can be performed on the entire outline of the printed figure.

  In another preferred aspect, the center mesh region is symmetric with respect to a center line parallel to a pair of sides of the figure forming region and asymmetric with respect to another center line parallel to the other pair of sides of the figure forming region. The first and second through holes are formed. The third through hole is formed in the peripheral mesh region along at least one of the other pair of sides of the figure forming region.

  In this case, since the first and second through holes are formed symmetrically with respect to the center line parallel to the pair of sides of the graphic forming region, the central mesh region has an aperture ratio of a portion along the pair of sides of the graphic forming region. Can be made uniform. On the other hand, in the center mesh region, the first and second through holes are formed asymmetrically with respect to another center line parallel to the other pair of sides of the figure forming region. The aperture ratio of the portion along at least one of the sides cannot be made uniform. Therefore, a third through hole is formed along at least one of the other pair of sides in the figure forming region. As a result, the aperture ratio can be made uniform, and good printing without blurring or rubbing can be performed on the entire outline of the printed figure.

  Preferably, the third through hole is formed along each side of the graphic forming region in the frame-shaped peripheral mesh region along each side of the graphic forming region.

  In this case, each side of the printed figure is formed by a paste that has passed through the third through-hole formed along each side of the figure forming region. Therefore, it is possible to prevent the entire outline of the printed figure from bleeding or rubbing.

Before SL peripheral mesh region, wherein the third through hole having a smaller opening than the opening of the first and second through-holes, are formed in a pitch smaller than the first and second through-holes Yes.

  In this case, since the paste forming the outline of the printed figure and the vicinity thereof is applied more uniformly from the third through hole in the peripheral mesh region to the printing material, the printing is more difficult to spread and more difficult to rub.

  Preferably, the opening of the third through-hole is rectangular, the long sides of the opening are adjacent to each other, the pair of short sides of the opening is in a straight line, and parallel to the side of the figure forming region. Is arranged.

  In this case, the third through holes are arranged at a short pitch on a straight line. Thereby, since the excessive discharge of the paste toward the side of the graphic formation region where they are adjacent is suppressed from the opening of the third through hole, the outline of the printed graphic becomes more difficult to spread.

  According to the present invention, it is possible to perform good printing without blurring or rubbing on the outline of a printed figure.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  <Example> The screen printing plate 10 of the Example which is the 1st Embodiment of this invention is demonstrated referring FIGS. 1-3.

  FIG. 1 is a cross-sectional view schematically showing the basic configuration of the screen printing plate 10. As shown in FIG. 1, the screen printing plate 10 includes a metal film 12 and a frame 18 that is attached to the metal film 12. The metal film 12 has a two-layer structure including a support layer 14 and a mesh layer 16 bonded to the support layer 14. The metal film 12 is formed by an electroforming method, for example, similarly to a conventional screen printing plate.

  A plurality of openings 15 penetrating between the main surfaces 14a and 14b are formed in the support layer 14. The mesh layer 16 is bonded to one main surface 14 b of the support layer 14. In the mesh layer 16, a through hole 17 is formed in a figure forming region 20 that faces the opening 15 of the support layer 14.

  When printing using the screen printing plate 10, the paste is supplied onto the mesh layer 16 on the inner side of the frame 18 with the other main surface 14 a of the support layer 14 in contact with the substrate. Then, for example, the squeegee is moved along the mesh layer 16 in contact with the mesh layer 16, and the paste is extruded from the through-hole 17 of the mesh layer 16 to the opening 15 side of the support layer 14, thereby opening the opening on the substrate. A paste is applied to a portion facing 15. A printed figure is formed on the substrate by the applied paste.

  FIG. 2 is a bottom view of the main part of the screen printing plate 10 as viewed from the substrate side along the line AA in FIG. Specifically, as shown in FIG. 2, the opening 15 of the support layer 14 and the figure forming region 20 of the mesh layer 16 are rectangular. The figure forming area 20 includes a frame-shaped peripheral mesh area 22 having a pair of short sides 22p and long sides 22q along each pair of short sides 20p and long sides 20q of the figure forming area 20, and a peripheral mesh area 22 And a rectangular central mesh region 24 surrounded by the surrounding mesh region 22.

  A honeycomb structure portion is formed in the central mesh region 24 of the figure forming region 20. That is, a plurality of first through holes 17a having the same size and shape and a plurality of second through holes 17b and 17c are formed in the central mesh region 24.

  The first through hole 17a has a regular hexagonal opening. The first through-holes 17a are arranged in a honeycomb structure at intervals so that a pair of opposite sides among the six sides of the regular hexagonal opening are parallel to the short side 20p of the figure forming region 20 Has been.

  The second through holes 17b and 17c are adjacent to the first through hole 17a with a space therebetween, and have an opening having a shape different from that of the first through hole 17a. The openings of the second through holes 17b and 17c have polygonal openings in which a part of the regular hexagon of the opening of the first through hole 17a is cut out. The notched sides 17x and 17y of the opening are along the sides 24x and 24y of the central mesh region 24.

  The central mesh region 24 of the figure forming region 20 has a line-symmetric shape on the left and right and up and down in FIG. 2 as a whole. That is, the center mesh area 24 of the figure forming area 20 is symmetric with respect to the center line 21p parallel to the pair of short sides 20p of the figure forming area 20, and is another center parallel to the pair of long sides 20q of the figure forming area 20. It is formed symmetrically with respect to the line 21q. More specifically, in the central mesh area 24 of the figure forming area 20, the second through 17 c having a pentagonal opening is arranged on the long side 20 q side of the figure forming area 20, and the short side of the figure forming area 20 On the 20p side, first through holes 17a having regular hexagonal openings and second through holes 17b having trapezoidal openings are alternately arranged.

  The first through hole 17a may have a hexagonal opening other than a regular hexagon. If the opening of the first through-hole is a line-symmetric shape with respect to a center line parallel to the center lines 21p and 21q of the graphic forming area 20, the central mesh area 24 of the graphic forming area can be configured line-symmetrically.

  By making the mesh of the center mesh region 24 into a honeycomb mesh, the strength of the mesh can be increased.

  A lattice structure is formed in the peripheral mesh region 22 of the figure forming region 20. In other words, a plurality of third through holes 17p having the same size and shape having openings arranged at equal intervals along the short side 20p of the figure forming region 20 are formed in the short side portion 22p of the peripheral mesh region 22. ing. A plurality of third through holes 17q of the same size and shape having openings arranged at equal intervals along the long side 20q of the figure forming region 20 are formed in the long side portion 22q of the peripheral mesh region 22. . The third through hole 17p of the short side portion 22p and the third through hole 17q of the long side portion 22q are different from each other in opening area and arrangement interval. But you may comprise so that opening area and / or arrangement | positioning space | interval dimension may become the same.

  The outline of the printed figure and its vicinity are formed by the paste that has passed through the third through holes 17p, 17q of the peripheral mesh region 22. In the short side portion 22p and the long side portion 22q of the peripheral mesh region 22, the openings of the third through holes 17p and 17q having the same size and the same shape are formed on the short side 20p or the long side 20q of the figure forming region 20, respectively. It is arranged at equal intervals along. Therefore, the paste that has passed through the third through holes 17p and 17q in the peripheral mesh region 22 is distributed substantially uniformly on the substrate, and the contour of the printed figure and its vicinity are formed substantially uniformly. As a result, it is possible to perform good printing without blurring or rubbing on the outline of the printed figure.

  When the third through holes 17p and 17q are formed along all the sides of the graphic forming region 20, it is possible to prevent the entire contour of the printed graphic from bleeding or rubbing.

  However, if the third through-hole is formed along at least one side of the graphic formation region, the effect of preventing the outline of the printed graphic corresponding to that side from bleeding or rubbing can be obtained. A configuration in which the third through hole is formed along only some of the sides of the region 20 is also possible. For example, the third through hole 17p may be formed only on the short side 20p side of the figure forming region 20. Since the first through hole 17a having a regular hexagonal opening and the second through hole 17b having a trapezoidal opening are alternately arranged on the short side 20p side of the figure forming region 20, a pentagonal opening is formed. Bleeding and rubbing are more likely to occur on the outline of the printed figure than on the long side 20q side of the figure forming region 20 in which the second through holes 17c having the same are disposed. Therefore, even if the third through hole 17p is formed only on the short side 20p side of the graphic forming region 20, it is possible to perform printing with less blurring and rubbing on the outline of the printed graphic as compared with the conventional case.

  In the present invention, the third through hole is formed in the peripheral mesh region, and when the third through hole is not formed along a certain side of the graphic forming region, the side of the graphic forming region is formed on that side. There is no surrounding mesh area along the line.

  The third through-hole 17p formed in the short side portion 22p of the peripheral mesh region 22 of the figure forming region 20 has a rectangular opening, and the long sides of the openings are adjacent to each other and arranged in a straight line. ing. That is, the pair of short sides of the openings are arranged on a straight line. One short side 17u opposite to the center mesh region 24 of the opening of the third through hole 17p is opposed to the short side 20p of the graphic forming region 20 with a space therebetween, and is opposed to the short side 20p of the graphic forming region 20 It is arranged in parallel and at equal intervals along.

  The third through hole 17q formed in the long side portion 22q of the peripheral mesh region 22 of the figure forming region 20 has a rectangular opening, and the long sides of the openings are adjacent to each other and arranged in a straight line. ing. That is, the pair of short sides of the openings are arranged on a straight line. One short side 17v opposite to the center mesh region 24 of the opening of the third through hole 17q is opposed to the long side 20q of the graphic forming region 20 with a space therebetween, and is opposed to the long side 20q of the graphic forming region 20 It is arranged in parallel and at equal intervals along.

  Thus, when the short sides 17u and 17v of the rectangular openings of the third through holes 17p and 17q are parallel to the sides 20p and 20q of the graphic forming region 20 adjacent to each other, the third through holes 17p are formed. , 17q are arranged at a short pitch on a straight line. Thereby, since the excessive discharge of the paste toward the sides 20p and 20q of the graphic forming region 20 adjacent to the third through holes 17p and 17q is suppressed, the outline of the printed graphic is more difficult to spread. Become.

  The third through holes 17p and 17q in the peripheral mesh region 22 have openings smaller than the first through holes 17a and the second through holes 17b and 17c in the central mesh region, and the first through holes in the central mesh region. It is formed with a smaller pitch than the holes 17a and the second through holes 17b and 17c. Therefore, the paste that forms the outline of the printed figure and the vicinity thereof is more uniformly applied to the printing material from the third through holes 17p and 17q of the peripheral mesh region 22, so that the printing is more difficult to spread, It becomes difficult to rub.

  In the present embodiment, in the figure forming region 20, the aperture ratio of the portion where the regular hexagonal first through hole 17a is disposed, and other portions, that is, the second through holes 17b and 17c and the third hole It is designed so that the aperture ratio of the portion where the through holes 17p and 17q are arranged is substantially equal.

Here, the aperture ratio is an area ratio of openings per unit area (openings of through holes). For example, the opening ratio of the regular hexagonal first through-hole 17a is obtained by the following equation 1 when the interval between opposing sides is a and the line width of the mesh is b as shown in the explanatory diagram of FIG. be able to.
Opening ratio (%) = a ² ÷ (a + b) ² × 100 (Formula 1)

  Since the aperture ratio is different between the portion where the first through-hole 17a is disposed and the portion where the second through-holes 17b and 17c are disposed, the third through-holes 17p and 17q may The aperture ratio is adjusted to be substantially equal. As described above, the opening area and the arrangement interval of the third through hole 17p in the short side portion 22p and the third through hole 17q in the long side portion 22q of the peripheral mesh region 22 of the figure forming region 20 are different. The reason for this is to adjust the aperture ratios that are different between the sides 24x and 24y of the central mesh region 24 to be substantially equal.

  Thus, by making the aperture ratio uniform in the figure forming area 20, the first through hole 17a, the second through holes 17b, 17c and the third through holes 17p, 17q of the figure forming area 20 are transmitted. As a result, the amount of paste per unit area supplied to the printing material becomes uniform, so that the paste can be more uniformly applied to form a uniform printed figure.

  The aperture ratio is desirably 30% to 40%. If the aperture ratio is larger than 40%, it causes bleeding of printed figures and strength reduction. On the other hand, if the aperture ratio is smaller than 30%, the printed figure is rubbed. Further, it is desirable that the aperture ratio be as uniform as possible in the figure forming region 20, but there may be partial variations in aperture ratio within a range where there is no practical problem. Specifically, a variation of ± 5% is practically acceptable.

  In the present embodiment, the openings of the third through holes 17p and 17q have the same size and the same shape in order to reduce the processing variation, but the present invention is not limited to this. In order to make the aperture ratio in the figure forming region 20 more uniform, the opening areas and arrangement intervals of the third through holes 17p and 17q may be partially different.

  Next, Modifications 1 to 4 of the present invention will be described with reference to FIGS. Below, it demonstrates centering on difference with an Example, and the same code | symbol is used for the same component as an Example.

  <Modification 1> FIG. 4 is an enlarged bottom view of a main part of a screen printing plate according to a first modification as viewed from the substrate side in the same manner as FIG. As shown in FIG. 4, the screen printing plate of the first modification is different from the embodiment in the shape of the third through-hole 17s formed in the peripheral mesh region 22 of the figure forming region 20 of the mesh layer 16. ing. The third through-holes 17s have substantially equilateral triangular openings, and are formed at equal intervals and alternately inverted. Although not shown in the center mesh region 24 of the figure forming region 20, first and second through holes are formed as in the embodiment.

  <Modification 2> FIG. 5 is an enlarged bottom view of a main part of a screen printing plate according to a second modification, as viewed from the substrate side, similarly to FIG. As shown in FIG. 5, the screen printing plate of the second modified example is different from the embodiment in the shape of the third through-hole 17 t formed in the peripheral mesh region 22 of the figure forming region 20 of the mesh layer 16. ing. The third through holes 17t have substantially circular openings and are formed at equal intervals. Although not shown in the center mesh region 24 of the figure forming region 20, first and second through holes are formed as in the embodiment.

  <Modification 3> FIG. 6 is a bottom view of a main part of a screen printing plate according to a third modification as viewed from the substrate side in the same manner as FIG. As shown in FIG. 6, in the screen printing plate of the third modified example, the center mesh region 24 of the figure forming region 20 of the mesh layer 16 is asymmetrically formed both on the left and right and top and bottom in the drawing. That is, in the center mesh region 24, the openings of the first through holes 17a and the second through holes 17d to 17g are asymmetrically arranged on the left and right as well as up and down in the drawing.

  On the other hand, in the short side portion 22p and the long side portion 22q of the peripheral mesh region 22 of the figure forming region 20 of the mesh layer 16, the openings of the third through holes 17p and 17q are arranged at equal intervals as in the embodiment. Yes. Therefore, it is possible to perform good printing without blurring or rubbing on the outline of the printed figure.

  In the conventional screen printing plate, in order to enable printing without bleeding or rubbing, the shape of the honeycomb structure part, that is, the arrangement of the openings, is configured to be symmetrical with respect to the left and right and / or up and down. For this reason, when the size of the figure forming region is changed, it is necessary to change the size of the hexagonal openings of the mesh holes so that the shape of the honeycomb structure portion is axisymmetric.

  On the other hand, in the present invention, by forming the third through hole in the peripheral mesh region, the aperture ratio in the graphic forming region can be adjusted to be uniform, so that even if the size of the graphic forming region changes There is no need to change the size of the first through hole formed in the central mesh region and having a hexagonal opening.

  Therefore, since the first through hole in the center mesh region can be designed with an optimum size according to the physical properties of the paste, the printability of the present invention is improved as compared with the prior art.

  <Modification 4> FIG. 7 is a bottom view of an essential part of a screen printing plate according to a fourth modification as viewed from the substrate side in the same manner as FIG. As shown in FIG. 7, the center mesh region 24 of the figure forming region 20 of the mesh layer 16 is formed symmetrically in the left and right and asymmetric in the vertical direction in the drawing.

  The central mesh area 24 of the figure forming area 20 can make the aperture ratio of the part along the short side 20p of the figure forming area 20 uniform, but the opening of the part along at least one of the long sides 20q of the figure forming area 20 The rate cannot be made uniform. Therefore, a plurality of third through holes 17q having the same shape are formed at equal intervals in the long side portion 22q of the peripheral mesh region 22. As a result, the aperture ratio can be made uniform, and good printing without blurring or rubbing can be performed on the entire outline of the printed figure.

  <Experimental example> Next, the effect of this invention is demonstrated using an experimental result.

In the screen printing plate of the comparative example of FIG. 9A, only the honeycomb structured mesh is formed in the figure forming region of the mesh layer, and the same method as the manufacturing example of the embodiment of the present invention of FIG. It was made with.

  As shown in FIG. 9B, the outline of the printed figure printed using the screen printing plate of the comparative example is blurred or rubbed.
