Description

  The present invention relates to a method for producing a screen printing plate, and more particularly to a method for producing a screen printing plate provided with a printing sheet formed by plating.

  In an electronic component manufacturing process, a screen printing plate provided with a printing sheet is used to print conductive patterns such as electrode pads and wiring. The printed sheet is produced using an electroforming technique. That is, a first layer plating film having a mesh hole is formed on a conductive base material, and then a second layer having an opening corresponding to a printed figure (printed figure hole) is formed on the first layer. A plated sheet is formed, and then a plated sheet in which the first and second layer plated films are integrally formed is peeled from the base material, thereby producing a printed sheet.

  The screen printing plate provided with the printing sheet formed by plating has (a) the shape and arrangement of the mesh holes in the first layer are the openings in the second layer (printing) so that desired printing quality and printing characteristics can be obtained. (B) The thickness of the first layer (mesh hole) and the second layer (opening) can be freely selected to ensure the thickness of the applied coating and the shape of the printed figure. . Because of these features, screen printing plates with printed sheets formed by plating have printing quality (print line shape sharpness, blurring prevention, coating thickness uniformity, and control of the coating thickness at any point). It is very effective for forming the necessary fine lines.

  The print sheet is used in a state of being attached to a print frame. As a method for pasting a printing sheet, a construction method using a combination screen plate structure and a direct pasting construction method without using a support rod are generally used.

  In the construction method using the combination screen plate structure, a screen with a screen 紗 to be affixed to a printing frame is prepared, and the outer periphery of the plating sheet (printing sheet) is attached to the screen 固 着, and the inner screen 紗 is cut. By removing, a necessary tension is applied to the print sheet (see, for example, Patent Document 1).

  In the direct pasting method, a frame that has a frame-like frame frame attached to a printing frame is prepared, and the plating sheet (printing sheet) formed by plating is not peeled off from the base material. After a plating sheet (printing sheet) is directly attached and fixed to the frame frame, the base material is peeled off from the plating sheet (printing sheet).

JP 2003-326869 A

  For screen printing plates, in order to ensure stable quality and reduce costs in printing, it is indispensable to reduce the size of one chip size and increase the number of plates in the plate. There is a need for a print sheet that can handle the above. For this purpose, in addition to improving the fine line print quality, it is essential to ensure the placement position accuracy (coordinate position accuracy) of each printed figure, which is indispensable for the lamination accuracy of printed figures. In order to ensure the coordinate position accuracy of the printing sheet, a direct pasting method in which the plating sheet is directly pasted on the frame frame is advantageous.

  However, when the size is increased by increasing the number of copies and the ultra-thin figure (the line width of the figure is 15 μm or less) is arranged on the entire surface, the coordinate position accuracy is ensured in the entire area (coordinate position guarantee of ± 10 μm). It is very difficult to stably supply possible screen printing plates.

In order to secure the coordinate position accuracy of each placed figure, it is indispensable to manage the internal stress of the plating bath, which affects the deviation from the reference position in the direct bonding method. For example, it affects the internal stress of the plating foil. The concentration of the brightening agent and the bath concentration of NiCl ₂ are controlled. Further, since a certain tension is required after the direct pasting plate making, the internal stress of the plating foil is controlled as a tensile stress. For this reason, the arrangement position of the outermost peripheral figure in the rectangular area is shifted to the coordinate position near the center (the direction in which the plating foil shrinks) with respect to the reference position, and the amount of deviation is in the outer peripheral part of the rectangular area. The four corners and the central part of each side show different tendencies. In other words, a “pincushion” deviation occurs when the arrangement coordinate positions of the outer peripheral figure of the rectangular area are connected, and this deviation is different (non-equal pitch) cannot be handled by the total pitch dimension correction of the original mask. It is very difficult to correct this pincushion deviation.

  From the above situation, the production of screen printing plates that can guarantee the placement coordinate position of all graphics in the rectangular area with higher accuracy (for example, deviation within ± 5 μm in the whole area) The coordinate position of each side center must be controlled, and it is extremely difficult to satisfy the required quality, which has been a drag on the manufacture of large-sized ultra-small and fine line figures.

  In view of such circumstances, the present invention is intended to provide a method for producing a screen printing plate that can uniformly improve the positional accuracy of printed graphic holes in the entire printing sheet.

  In order to solve the above problems, the present invention provides a method for producing a screen printing plate having the following configuration.

  The method for producing a screen printing plate includes first to fourth steps. In the first step, a plated body and a frame are prepared. The plated processed body includes a base material and a printed sheet formed on the base material. The printed sheet includes a first layer formed by plating on the base material and a second layer formed by plating on the first layer. The first layer has mesh holes penetrating between the principal surfaces of the first layer, and the second layer has printed graphic holes penetrating between the principal surfaces of the second layer. The frame includes a printing frame having a rectangular opening and four linear portions coupled to the rectangle, and is fixed to the printing frame, and the four linear portions are located inside the opening of the printing frame. And a protruding frame. In the second step, the plated body is disposed inside the printing frame, and an intermediate portion between both ends of the linear portion of the frame frame that protrudes inside the opening of the printing frame and the both ends. Only the intermediate part and the print sheet are fixed using a first adhesive. In the third step, the base material is separated from the printed sheet after the second step. In the fourth step, after the third step, the both end portions of the linear portion of the frame frame that protrudes inside the opening of the printing frame and the printing sheet are used as a second adhesive. To fix.

  In the above method, the first and second adhesives may be the same or different.

  According to the above method, when the base material of the plated body is separated from the print sheet, the print sheet is not bonded to both ends of the linear portion of the frame frame that protrudes inside the opening of the print frame. That is, the four corners of the print sheet are not bonded to the frame. As a result, it is possible to eliminate the restraint at both ends of the rigid portion compared to the intermediate portion of the straight portion of the frame frame, to uniformly deform the print sheet, and to improve the positional accuracy of the printed figure holes uniformly in the entire print sheet.

  Preferably, in the second step, the printing is performed in a state where a sheet material is sandwiched between the both end portions of the linear portion of the frame frame that protrudes inside the opening of the printing frame and the printing sheet. Of the both ends of the linear portion of the frame frame that protrudes inside the opening of the frame and the intermediate portion, only the intermediate portion and the print sheet are fixed using the first adhesive. Prior to the fourth step, the sheet material is removed from between the frame frame and the printed sheet.

  In this case, by using the sheet material, in the second step, only the intermediate portion of the straight portion of the frame frame that protrudes inside the opening of the print frame and the print sheet can be reliably and easily fixed. Note that the sheet material may be removed before the third step, may be removed during the third step, or may be removed after the third step.

  Preferably, the first adhesive is in a gel form and the second adhesive is in a liquid state.

  In this case, the operations of the second and fourth steps are facilitated.

  When the screen printing plate is produced by the method of the present invention, the positional accuracy of the printed graphic hole can be evenly increased in the entire printing sheet.

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

  <Example 1> The manufacturing method of the screen printing plate 10 of Example 1 is demonstrated, referring FIGS. 1-10.

  As schematically shown in the cross-sectional view of FIG. 4 (5), in the screen printing plate 10, the printing sheet 11 formed by electrolytic plating is held on the printing frame 20 via the frame frame 22.

  1 and 2 are cross-sectional views schematically showing the manufacturing process of the printing sheet 11. The manufacturing process of the printing sheet 11 will be described with reference to FIGS.

  (1) First, as shown in FIG. 1A, a conductive base material 50 having a reference surface 50a having a predetermined surface roughness is prepared. For example, surface treatments such as alkali degreasing, water washing, acid treatment, water washing, and drying are performed on stainless steels SUS430 and SUS304 having a surface roughness Ra of 0.01 μm to 1 μm.

  (2) Next, as shown in FIG. 1 (2), photosensitivity for forming mesh holes 13 in the first layer 12 on the reference surface 50a of the base material 50 that has been subjected to surface treatment by degreasing cleaning and acid treatment. A resist layer 52 is formed. Even if the photosensitive resist layer 52 is formed by bonding a dry film photosensitive resist to the reference surface 50a of the base material 50 with a laminator, a liquid photosensitive resist is applied to the reference surface 50a of the base material 50 with a spin coater. May be.

  When growing the mesh portion of the first layer 12 by electrolytic plating, if the photosensitive resist thickness is lower than the mesh thickness, the opening portion of the mesh hole becomes an overhang shape, and the opening size accuracy of the mesh hole cannot be guaranteed. . In order to prevent this, the thickness of the photosensitive resist layer 52 is set to a thickness larger than the mesh portion thickness (that is, the thickness of the first layer 12). The film thickness range of the photosensitive resist layer 52 is about 10 μm to 50 μm, and the thickness of the photosensitive resist layer 52 is about +2 to +10 μm thicker than the thickness of the mesh portion to be plated (the thickness of the first layer 12). Select.

  (3) Next, as shown in FIG. 1 (3), exposure is performed as indicated by an arrow 62 using an original mask 60. On the original mask 60, a mesh figure 63 for forming the mesh hole 13 is drawn. Here, since a negative photosensitive resist is used for the photosensitive resist layer 52, in the original mask 60, the figure forming the resist pattern is a transparent figure. When a positive photosensitive resist is used for the photosensitive resist layer 52, the figure forming the resist pattern is an opaque figure.

  There are various mesh hole shapes such as rectangle, rhombus, fan shape, triangle, honeycomb shape, and the size and number of arrangements all satisfy the desired printing characteristics (shape, dimensions, coating thickness, uniformity, edge linearity, etc.). Thus, selection and arrangement of mesh wire diameter, hole diameter, number of holes, hole shape and the like are performed. Actually, the mesh hole size is about 10 μm to 100 μm, and the mesh wire diameter is about 10 μm to 50 μm for good print quality.

  (4) Next, the exposed photosensitive resist layer 52 is developed. As a result, a resist pattern 53 corresponding to the mesh pattern 63 is formed on the reference surface 50 a of the base material 50 as shown in FIG.

  (5) Next, with the resist pattern 53 formed on the reference surface 50a of the base material 50, electrolytic plating is applied to the base material 50, and as shown in FIG. 2 (5), the reference surface 50a of the base material 50 is applied. A first layer 12 is formed thereon. For example, as the electrolytic plating bath, a sulfamic acid Ni bath excellent in stress control of the plating film is used and formed by electrolytic Ni plating. The internal stress of the foil in the sulfamic acid plating bath is controlled to the tension side by the addition of a stress modifier (halogen Ni, brightener), and the plating thickness forming the mesh part is proportional to the amount of electroplating electricity (current value x conduction time) Since there is a relationship, thickness control is performed by setting a plating electric quantity corresponding to a desired plating thickness. The actual first layer mesh part plating thickness varies depending on the paste viscosity to be used and the desired print quality (print coating thickness, suppression of bleeding), but also includes the relationship with the mesh opening ratio, about 5 μm to 50 μm thickness. Set by range.

  (6) Next, after the electroplating of the first layer 12 is completed, the resist pattern 53 is peeled off as shown in FIG. The resist pattern 53 is peeled and removed by completely dissolving and removing the resist pattern 53 by shower spraying or immersing an alkali solution or an organic solvent-containing solution, and then washing and removing the alkali residue on the surface by a subsequent water washing treatment. At this point, the process of forming the mesh holes 13 in the first layer 12 is finished.

  (7) Next, the same steps as in the above (2) to (6) are repeated to form the second layer 14 having the printed pattern holes 15 on the first layer 12. In the original exposure process of the second layer 14, care is taken to ensure consistency with the mesh portion of the first layer 14, and the mesh hole 13 of the first layer 12 and the printed pattern hole 15 of the second layer 14 are aligned. An all-metal printing sheet 11 that is well integrated is formed. FIG. 2 (7) shows a state in which the electroplating of the second layer 14 is completed and a resist stripping process is performed. In the printing sheet 11, the plating films of the first layer 12 and the second layer 14 are integrally formed on a base material 50.

  Next, the process of manufacturing a screen printing plate using a plated product will be described with reference to FIGS. 3 and 4 are cross-sectional views schematically showing the manufacturing process of the screen printing plate.

  As shown in FIG. 3 (1), an adhesive 30 is applied to the lower surface 20 b of the printing frame 20, and the plate-like frame frame 22 is fixed to the lower surface 20 b of the printing frame 20. As schematically shown in the plan views of FIGS. 5A and 5B, the printing frame 20 is a frame-shaped member having a rectangular opening 21, and the frame frame 22 has a frame shape having a rectangular opening 23. It is a member.

  6A is a schematic view of the frame body 28 to which the printing frame 20 and the frame frame 22 are fixed as viewed from the frame frame 22 side. FIG. 6B is an upper surface 20a side of the printing frame 20. It is the schematic diagram seen from. As shown in FIGS. 6A and 6B, in the frame body 28, the frame frame 22 protrudes inside the print frame 20, and the opening 23 of the frame frame 22 is arranged inside the print frame 20.

  For example, the frame 22 is formed of a material such as a stainless plate having a thickness of 0.1 to 0.5 mm. The inner dimension of the opening 23 of the frame frame 22 is made approximately 20 to 50 mm smaller than the inner dimension of the opening 21 of the printing frame 20. The frame frame 22 is cut out by laser processing or the like, and edge burrs are removed.

  Next, as shown in FIG. 3B, the printed sheet 11 of the plated body 18 is bonded to the frame frame 22 of the frame body 28.

  The plated body 18 is cut to a size smaller than the opening 21 of the printing frame 20 and larger than the opening 23 of the frame frame 22. At this time, the print sheet 11 is cut together with the base material 50 in a state where the print sheet 11 remains attached to the base material 50.

  In order to fix the outer periphery of the cut print sheet 11 and the print frame 20 side (that is, the squeegee surface side) of the frame frame 22, the four straight lines of the frame frame 22 that protrude inside the opening 21 of the print frame 20 The adhesive 32 is applied to the part. At this time, as shown in the schematic diagram of FIG. 7, the adhesive 32 is applied only to the middle portion of the four straight portions of the frame frame 22 protruding inside the opening 21 of the printing frame 20, and both end portions ( The adhesive 32 is not applied to the portion surrounded by the chain line 70 in FIG. When the gel adhesive 32 is used, the adhesive 32 can be easily applied.

  Next, as shown in FIG. 4 (3), the print sheet 11 is brought into close contact with the frame frame 22, and the print sheet 11 is fixed to the frame frame 22 by drying the adhesive. At this time, the four corners of the print sheet 11 are not fixed to the frame 22.

  For example, a sheet material (not shown) (for example, a PET film) is disposed at the four corners of the outer periphery of the print sheet 11, and the frame frame 22 protrudes from the four corners of the print sheet and the opening 21 of the print frame 20. If the sheet material is bonded between both ends of the straight line portion, the four corner portions of the print sheet 11 can be reliably and easily prevented from adhering to the frame frame 22. When the sheet material is sandwiched, the sheet material is removed from between the print sheet 11 and the frame frame 22 before bonding the non-bonded portion.

  Further, as shown in FIG. 8A, which is a schematic view of the printing sheet 11 as viewed from the upper surface 20 a side of the printing frame 20, the holes of the printing sheet 11 are closed with the base material 50 at this time.

  Next, as shown in FIG. 4 (4), the base material 50 is peeled off from the printing sheet 11. As a result, as shown in FIG. 8B, which is a schematic view of the printing sheet 11 viewed from the upper surface 20 a side of the printing frame 20, the holes of the printing sheet 11 are not blocked.

  The print sheet 11 is restrained by fixing the middle part of the four linear portions to the frame frame 22, whereas the four corners of the print sheet 11 are not fixed to the frame frame 22. Therefore, when the base material 50 is peeled off, the four corner portions of the printing sheet 11 are deformed by internal stress.

  Next, the entire outer periphery of the print sheet 11 and the entire periphery of the frame frame 22 are bonded by using an adhesive between the free portions (non-adhesive portions) at the four corners of the print sheet 11 and the frame frame 22. Is fixed, the screen printing plate 10 shown in FIG. 4 (5) is completed. When a liquid adhesive is used, the adhesive can be easily supplied into the gap between the print sheet 11 and the frame frame 22 from the direction indicated by the arrow 34 in FIG. By fixing the print sheet 11 and the frame frame 22 all around, it is possible to prevent the print paste from leaking from the joint between the print sheet 11 and the frame frame 22.

  Next, an example of producing the screen printing plate 10 of Example 1 will be described. The printing frame 20 had an outer shape of 410 mm × 410 mm, an opening size of 350 mm × 350 mm, a thickness of 25 mm, and was made of aluminum. The frame frame had an outer shape of 390 mm × 390 mm, an opening size of 290 mm × 290 mm, a thickness of 0.4 mm, and a material made of stainless steel. The printing sheet 11 was formed by electrolytic Ni plating, and had an outer shape of 320 mm × 320 mm, a thickness of the first layer 12 of 15 μm, and a thickness of the second layer of 30 μm. On the first layer of the printing sheet, eight reference figures arranged in a straight line parallel to each side of the printing sheet were formed near both ends and the middle position of each side of the printing sheet. A cyanoacrylate gel-like and liquid instantaneous adhesive was used for fixing the printed sheet and the frame.

  The non-adhesive length indicated by the symbol L in FIG. 7, that is, the length in which the adhesive is not applied in the first adhering step at both ends of the linear portion of the frame frame 22 protruding inside the opening 21 of the printing frame 20. Samples of 1 cm, 2 cm, 3 cm, and 4 cm were prepared. As Comparative Example 1, a sample having a non-adhesion length L of 0 cm was also prepared. The position of the reference graphic formed on the first layer of the printed sheet was measured.

  FIG. 9 is a graph schematically showing the displacement of the print sheet. The gray circle indicates the design position of the reference graphic, and the black circle indicates a deviation (displacement) from the design position of the reference graphic. Eight rectangular areas surrounded by bold lines show an enlarged view of the displacement of the reference graphic with respect to the design position. As for the design position, three points are aligned along each side of the print sheet.

  From FIG. 9, it can be seen that the middle part of each side of the print sheet is positioned as designed, but the amount of displacement varies at the four corners of the print sheet in accordance with the non-bonding length L of the frame frame. As shown by arrows in FIG. 9, the positional deviations at the four corners of the printed sheet become closer to the center (inner side) of the printed sheet as the non-application length L becomes larger.

  FIG. 10 is a graph showing the relationship between the non-bonding length and the linearity of the printed sheet. That is, the positional deviation width in the direction perpendicular to each side is calculated for three reference figures formed in parallel with each side of the print sheet, and the maximum value of the positional deviation width for each side is plotted. From FIG. 10, by appropriately selecting a region where the corner portion of the print sheet is not adhered, the linearity of each side of the print sheet after pasting is improved, and the deformation of the print sheet may be uniform as a whole. I understand. By increasing the linearity of each side of the printed sheet, the entire printed sheet can be controlled so that the rectangular shape before pasting remains rectangular after pasting. The positional accuracy is improved, and it is possible to greatly contribute to the cost reduction in the printing process by making a fine figure and enlarging the plate.

  Moreover, since the intermediate part of each side of the printing sheet is bonded at the first time, the tension necessary for the printing sheet can be maintained. Therefore, even if it changes from the construction method of the comparative example 2 mentioned later, it is not necessary to reexamine the setting conditions at the time of printing, and an enlargement and a yield improvement can be performed efficiently.

  <Comparative example 2> The manufacturing process of the screen printing plate of the comparative example 2 is demonstrated, referring FIGS. 11-13.

  FIG. 11 is a cross-sectional view schematically showing the manufacturing process of the screen printing plate. In Comparative Example 2, a screen printing plate is produced in substantially the same manner as in Example 1.

  That is, as shown in FIG. 11 (1), the frame frame 22 is pasted on the print frame 20. Next, as illustrated in FIG. 11B, the base material 50 and the print sheet 11 are cut as they are and are arranged inside the opening 21 of the print frame 20, and the print sheet 11 and the frame frame 22 are bonded to the adhesive 32. To fix. At this time, unlike the first embodiment, as shown in the schematic diagram of FIG. 12, the adhesive 32 is applied to the entire periphery of the frame frame 22 protruding inside the opening 21 of the printing frame 20, and the printing sheet 11 and the frame The entire circumference of the frame 22 is fixed using an adhesive 32. Next, as shown in FIG. 11 (4), when the base material 50 is peeled off from the printing sheet 11, the screen printing plate 10x is completed.

  The screen printing plate of Comparative Example 2 was produced in such a process, and the coordinates of the reference graphic along the four sides of the printing sheet were measured in the same manner as in the production example of Example 1. The measurement results are schematically shown in FIG. In FIG. 13, a gray circle indicates a design position, and a black circle indicates a displacement with respect to the design position. Eight rectangular areas surrounded by bold lines show an enlarged view of the displacement with respect to the design position.

  From FIG. 13, it can be seen that the middle part of each side of the print sheet is substantially the design position, but the four corners of the print sheet are displaced (displaced) outside the design position. This is considered to be due to the fact that the vicinity of the four corners of the frame frame and the printing frame is higher in rigidity than the middle portion of the frame frame and the printing frame, and therefore the restraining force on the screen printing plate is different between the four corners and the middle portion.

  On the other hand, in Example 1, instead of fixing the frame frame and the plated metal sheet all around at once, the base material was peeled off after fixing the region other than the four corner portions, and then remained. The four corner areas are bonded. In Example 1, as shown in FIG. 9, by appropriately selecting the size of the region that is not bonded first, the displacement of the middle portion and the four corners of each side of the printed sheet can be made substantially equal.

  <Summary> As described above, by dividing the adhesion between the print sheet and the frame into two stages, the position accuracy of the printed graphic holes can be increased uniformly in the entire print sheet.

  The present invention is not limited to the above embodiment, and can be implemented with various modifications.

  For example, the range (size and shape) of both end portions (size and shape) that do not adhere to the frame frame in the first bonding process among the straight portions of the frame frame that protrudes inside the opening of the printing frame is the shape of the printing sheet, the frame frame, and the printing. What is necessary is just to select suitably according to the rigidity of a frame, etc., and it is not necessary to necessarily make the non-bonding length L of 2 directions the same. Further, the first layer and / or the second layer of the printed sheet may be formed on the base material by electroless plating.
