Japanese Patent No. 3462125 (Japanese Patent Laid-Open No. 2001-18549)

  In recent years, with the miniaturization of electronic components and the like, there has been a demand for finer print patterns in screen printing. In order to print a fine pattern, it is necessary to reduce the diameter of the mesh lines constituting the printing screen mesh. In order to reduce the diameter of the mesh line while maintaining the performance as a screen mesh for printing, it is necessary to increase the hardness of the mesh line.

  Usually, the screen mesh for printing is formed by cutting out from the roll raw material of a mesh base material. For this reason, when the printing screen mesh is formed from a mesh base material woven with a very fine mesh wire having high hardness, the mesh of the formed printing screen mesh is entangled due to the high hardness of the mesh wire. When the screen mesh for printing is wound, adhesion to the support screen mesh becomes difficult. In addition, misalignment of the printing screen mesh, breakage of the end portion, and the like may occur and workability may deteriorate. Furthermore, when it adhere | attaches in the state which the adhesion part floated, there exists a possibility that adhesive strength may fall and a tear may arise.

  The present invention has been made in order to solve the above problems, and a method for producing a screen plate capable of suppressing deterioration in workability at the time of producing a screen plate and preventing adhesion failure of a printing screen mesh. The purpose is to provide.

  In order to achieve the above object, a method of manufacturing a screen plate according to the present invention includes a plate frame, a resin support screen mesh fixed to the plate frame, and a printing screen mesh fixed to the support screen mesh. A method for producing a screen plate comprising: a step of plating a screen mesh for printing by applying a tension; a step of stretching a mesh base material for constituting a screen mesh for support; The step of adhering and fixing the plated screen mesh with plating to the mesh base material, and the mesh base material with the screen mesh fixed to the inside of the adhesive area bonded to the screen mesh for printing Cutting and removing the area inside the bonding area, bonding and fixing the stretched mesh base material to the plate frame, and plating After the printing screen mesh decorated fixed to the mesh base material, characterized in that it comprises a step of peeling was applied to the printing screen mesh plating.

  The screen plate manufacturing method according to the present invention includes a plate frame, a resin supporting screen mesh fixed to the plate frame, and a printing screen mesh fixed to the supporting screen mesh. A method for producing a plate, comprising a step of plating a screen mesh for printing by applying tension, a step of stretching a mesh base material for constituting a supporting screen mesh, and a stretched mesh base material In addition, the step of adhering and fixing the screen mesh for printing that has been plated and the mesh base material to which the screen mesh for printing is fixed are cut inside the adhesion area bonded to the screen mesh for printing, After removing the inner area of the bonding area and the inner area of the bonding area, the stretched mesh base material is bonded to the plate frame. A step of constant, after fixing the mesh base material to the plate frame, characterized in that it comprises a step of peeling was applied to the printing screen mesh plating.

  According to each of the methods for producing a screen plate according to the present invention, plating is applied to the printing screen mesh in a state where tension is applied, so that curling is corrected and the printing screen mesh is flattened. The As a result, when the plated printing screen mesh is bonded and fixed to the mesh base material, it is possible to suppress the occurrence of misalignment or edge breakage. Further, in the subsequent process, the plating applied to the printing screen mesh is peeled off, so that the diameter of the mesh lines constituting the printing screen mesh is reduced, and a fine pattern can be printed.

  In the method for producing a screen plate according to the present invention, the above-described step of plating the screen mesh for printing by applying tension is stretched with the step of stretching the mesh base material for constituting the screen mesh for printing. It is preferable to have a step of adhering and fixing a mesh base material for constituting the screen mesh for printing to the frame and a step of plating the mesh base material fixed to the frame.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the figure, the same reference numerals are used for the same or corresponding parts.

(First embodiment)
First, based on FIG.1 and FIG.2, the structure of the screen plate 1 which concerns on 1st Embodiment is demonstrated. FIG. 1 is a schematic plan view showing a screen plate 1 according to the first embodiment. FIG. 2 is a schematic diagram showing a cross-sectional configuration in the II-II direction in FIG.

  The screen plate 1 includes a plate frame 10, a supporting screen mesh 20, and a printing screen mesh 30. The screen plate 1 is used, for example, for printing an electrode pattern on a green sheet in a manufacturing process of a multilayer chip capacitor.

  The plate frame 10 is a frame having two sides facing each other when viewed in the X-axis direction and two sides facing each other when viewed in the Y-axis direction. The plate frame 10 can be made of, for example, a lightweight metal material such as aluminum or a light alloy.

  The supporting screen mesh 20 has a sheet shape, and the shape thereof is rectangular. An opening 22 having a rectangular shape is formed substantially at the center of the supporting screen mesh 20. The outer edge of the supporting screen mesh 20 is fixed to the plate frame 10 over the entire circumference in a state where a predetermined tension is applied. The fixing of the support screen mesh 20 to the plate frame 10 can be realized by adhering the support screen mesh 20 and the plate frame 10 using an adhesive 40 such as an epoxy resin, for example. The supporting screen mesh 20 includes an adhesive region 24 bonded to the printing screen mesh 30 at the inner edge thereof.

  The supporting screen mesh 20 can be made of a synthetic resin material. For example, the supporting screen mesh 20 is a mesh (mesh) woven with synthetic resin fibers such as polyester as warp and weft, and is about 250 mesh (# 250), for example.

  The printing screen mesh 30 has a sheet shape, and the shape thereof is rectangular. The printing screen mesh 30 includes an adhesive region 32 bonded to the supporting screen mesh 20 at the outer edge thereof. The printing screen mesh 30 has an outer edge (an adhesive region 32 bonded to the supporting screen mesh 20) fixed to the supporting screen mesh 20 over the entire circumference so as to cover the opening 22 of the supporting screen mesh 20. . The fixing of the printing screen mesh 30 to the supporting screen mesh 20 can be realized, for example, by bonding the printing screen mesh 30 and the supporting screen mesh 20 using an adhesive 50 such as an epoxy resin.

  The printing screen mesh 30 is made of a metal material. For example, the printing screen mesh 30 is a mesh woven with ultrafine wires made of metal such as stainless steel as warp and weft, and for example, a mesh of about 360 mesh to 380 mesh (# 360 to # 380) is used.

  The printing screen mesh 30 includes a pattern forming region 34 inside an adhesive region 32 that is bonded to the supporting screen mesh 20. In this pattern formation region 34, a predetermined print pattern is formed by a portion in which the mesh opening is blocked by a sealing agent such as an emulsion and a portion not closed.

  Next, a manufacturing process of the screen plate 1 according to the first embodiment will be described with reference to FIGS. 3-14 is a schematic diagram for demonstrating the manufacturing process of the screen plate 1 which concerns on 1st Embodiment.

Process (1)
First, the mesh base material M2 for constituting the printing screen mesh 30 is cut out from the roll material, and a tension F1 is applied to the mesh base material M2 (see FIGS. 3 and 4). A tensioning means may be used as the tension applying means, and the mesh base material M2 may be pulled by the clamps C1 to C4 of the tensioning machine. Specifically, both ends of the mesh base material M2 in the X-axis direction are clamped by one set of clamps C1 and C2, and both ends of the mesh base material M2 in the Y-axis direction are clamped by another set of clamps C3 and C4. To do. Then, a tensile force TS1 is applied to these clamps C1 to C4 in the direction in which the mesh base material M2 is extended. The tensile force applied to the one set of clamps C1 and C2 is in the direction of extending the mesh base material M2 on the X axis, and the tensile force TS1 applied to the other set of clamps C3 and C4 is the mesh on the Y axis. This is the direction in which the base material M2 is stretched. Thereby, tension F1 will be given to mesh base material M2.

Process (2)
Next, the mesh base material M2 stretched is fixed to the frame 60 (see FIG. 5). The frame 60 is a rectangular frame. Thereby, the tension | tensile_strength F1 provided to the mesh base material M2 is substantially hold | maintained. In order to fix the mesh base material M2 to the frame 60, the mesh base material M2 may be bonded to the frame 60 using the adhesive 62.

  Subsequently, outside the frame 60, the mesh base material M2 is cut along the frame 60 (see FIG. 6). Thereby, the mesh base material M2 whose outer edge is fixed to the frame 60 is formed.

Step (3)
Subsequently, the mesh base material M2 fixed to the frame 60 is plated. In the present embodiment, the plating layer 36 is formed on the mesh base material M2 by electroplating. The material of the plating layer 36 is preferably nickel (Ni). The thickness of the plating layer 36 is preferably set to 1 μm or more, for example, and more preferably 3 μm or more. In addition to Ni, metal materials, such as copper (Cu), chromium (Cr), cobalt (Co), can be used for the material of a plating layer. Needless to say, the plating method is not limited to the electroplating method.

Step (4)
Next, the plated mesh base material M2 is cut inside the adhesion region (see FIG. 7). Thereby, the screen mesh 30 for printing cut | disconnected by the predetermined magnitude | size is obtained. The size for cutting the printing screen mesh is set according to the size of the green sheet on which the electrode pattern is printed, for example. By performing plating in a state where tension F1 is applied and curling is corrected, even when the tension F1 is removed from the frame 60 and the tension F1 is removed, the corrected curling does not return and flat printing is performed. A screen mesh 30 can be obtained.

Step (5)
Subsequently, the mesh base material M1 made of the above-described synthetic resin material (for example, polyester) is stretched (see FIGS. 8 and 9). The mesh base material M1 is stretched by pulling the mesh base material M1 with clamps C1 to C4 using a tensioning machine. Specifically, both ends of the mesh base material M1 in the X-axis direction are clamped by one set of clamps C1 and C2, and both ends of the mesh base material M1 in the Y-axis direction are clamped by another set of clamps C3 and C4. To do. Then, a tensile force TS2 is applied to these clamps C1 to C4 in the direction in which the mesh base material M1 is extended. The tensile force applied to the one set of clamps C1 and C2 is in the direction of extending the mesh base material M1 on the X axis, and the tensile force TS2 applied to the other set of clamps C3 and C4 is the mesh on the Y axis. This is the direction in which the base material M1 is stretched. As a result, the tension F2 is applied to the mesh base material M1.

Step (6)
Next, the screen mesh 30 for printing having been plated is fixed to the mesh base material M1 that has been stretched (see FIGS. 10 and 11). In this step, first, the printing screen mesh 30 is overlaid on a region P1 in the plane of the mesh base material M1. The region P1 has a rectangular shape, and is set substantially at the center of the mesh base material M1. The region P1 is slightly smaller than the printing screen mesh 30. In order to superimpose the printing screen mesh 30 on the region P1 of the mesh base material M1, after placing the printing screen mesh 30 on the base plate BP, the base plate BP is directed toward the region P1 of the mesh base material M1. The printing screen mesh 30 on the base plate BP may be brought into contact with the region P1 of the mesh base material M1.

  Subsequently, the printing screen mesh 30 is bonded to the periphery of the region P1 of the mesh base material M1. Specifically, the printing screen mesh 30 is bonded to the periphery of the area P1 of the mesh base material M1 so as to cover the area P1 of the mesh base material M1. For bonding, for example, the adhesive 50 is applied from the mesh base material M1 to the periphery of the region P1. Then, the adhesive 50 may be permeated between the mesh base material M1 and the screen mesh 30 for printing so that the adhesive 50 is cured. After bonding, the base plate BP is lowered and the base plate BP is separated from the printing screen mesh 30.

Step (7)
Next, the portion of the above-described region P1 (the portion indicated by the alternate long and short dash line in the figure) is removed from the mesh base material M1 (see FIG. 12). In this step, the mesh base material M1 is cut inside the bonding area 24 bonded to the printing screen mesh 30, and the area inside the bonding area 24, that is, the area P1 is removed. In the present embodiment, the mesh base material M <b> 1 is cut along the adhesion region 24 inside the adhesion region 24. Thereby, the opening 22 described above is formed.

Step (8)
Next, the stretched mesh base material M1 is fixed to the plate frame 10 (see FIG. 13). In order to fix the mesh base material M1 to the plate frame 10, the mesh base material M1 may be bonded to the plate frame 10 using the adhesive 40. The plate frame 10 is placed on a base plate (not shown).

  Subsequently, the mesh base material M1 is cut along the plate frame 10 outside the plate frame 10 (see FIG. 14). As a result, the supporting screen mesh 20 whose outer edge is fixed to the plate frame 10 is formed.

Step (9)
Next, the plating applied to the printing screen mesh 30 is peeled off. For example, nitric acid is used as a plating release agent. Only the plating applied to the printing screen mesh 30 is peeled off by adjusting the concentration of nitric acid, temperature, peeling time and the like.

  By these steps (1) to (9), the screen plate 1 having the above-described configuration is obtained.

  In addition, the order of each process is not restricted to this embodiment. For example, the step (8) for attaching the plate frame may be performed after the step (5), the step (6) or the step (9). Moreover, you may implement the process (9) which peels metal plating following the said process (7).

  As described above, according to the first embodiment, the mesh base material M2 is plated while being stretched and fixed to the frame 60, so that the curl is corrected and the mesh base material M2 is flattened. Is done. As a result, when the plated printing screen mesh 30 is bonded and fixed to the mesh base material M1, it is possible to suppress the occurrence of misalignment or edge breakage. As a result, it is possible to suppress deterioration in workability during the production of the screen plate and to prevent poor adhesion of the printing screen mesh 30.

  Further, in the subsequent step (9), since the plating applied to the printing screen mesh 30 is peeled off, the wire diameter of the mesh line constituting the printing screen mesh 30 becomes thin, and a fine pattern can be printed. Become.

  Subsequently, the mesh base material M1 is cut along the plate frame 10 outside the plate frame 10 (see FIG. 18). As a result, the mesh base material M1 whose outer edge is fixed to the plate frame 10 is formed.

Step (7)
Next, the printing screen mesh 30 plated is fixed to the mesh base material M1 fixed to the plate frame 10 (see FIGS. 19 and 20). At that time, the printing screen mesh 30 is fixed to a surface different from the surface on which the plate frame 10 is fixed. Since the method for fixing the supporting screen mesh 20 and the printing screen mesh 30 is the same as the fixing method described in step (6) of the first embodiment, the description thereof is omitted here.

  Since step (8) is the same as the removal method described in step (7) of the first embodiment, description thereof is omitted.

  Step (9) is the same as step (9) in the first embodiment, and a description thereof is omitted here. Through these steps (1) to (9), the screen plate 2 having the structure shown in FIGS. 15 and 16 is obtained.
