Description

  The present invention relates to a printing method and a method for forming a functional material pattern on a substrate with a high-thickness film while maintaining accuracy and fineness on the substrate surface, which is desired in the manufacturing process of electrical parts and the like.

Various patterning techniques are used in the process of making electrical parts and the like. The printing method is used as an inexpensive method. The thickness of the pattern by printing is generally several μm or less although a thick film is desired, and its function cannot be sufficiently achieved because the functional material is inked (FIG. 6). Further, there are problems such as poor dimensional accuracy and poor definition, and a better pattern formation method is desired.

Although thick printing such as electrode printing and PDP ribs is desired, silk printing capable of forming a thick film lacks accuracy and fineness.

Even in the gravure method capable of relatively thick printing that currently requires high accuracy, the film thickness obtained is several μm, and the required film thickness cannot be obtained. This proposal was devised in order to solve the problem of obtaining a film thickness of several tens of microns as high as silk printing by printing while obtaining high precision and high definition equivalent to gravure printing.

Means to solve the problem

This plan was devised to solve the above problems.
First, a depth and opening corresponding to the image required on the silicon rubber sheet surface are provided, and a rigid plate is pasted on the back surface to make the sheet wait for accuracy to form a silicon rubber intaglio (4).

    The functional material is filled in the concave portion of the silicon intaglio surface. After the adhesive material is additionally filled to solidify the functional material and make the surface sticky, all of the filled functional material is transferred to the substrate. As a result, the functional material is formed into a thick film to form a pattern.

The invention's effect

(1) In conventional printing, the functional material is wrapped in another resin, ie, a solvent or solvent, and used as an ink with appropriate printing properties. The material functions because the material is dispersed in the solvent or solvent. It has been damaged (Fig. 6-6). On the other hand, in this plan, since the material itself is first contacted and solidified with an adhesive, the density of the material is high (FIG. 1- (7)), and a pattern can be formed with little loss of the function of the material.

  (2) Since the pattern is formed using all of the material filled in the recess, the structure of the required height is selected by setting the depth and size of the recess and selecting the shape and size of the structural material to be filled. Can be formed.

BEST MODE FOR CARRYING OUT THE INVENTION

Fill the concave part of the intaglio plate made of silicon rubber with a functional material, and then fill with an adhesive, and the functional material is semi-solidified by the adhesive and the adhesive material is transferred to the substrate. Then, pattern formation with a functional material is performed.

The principle of claim 1 will be described with reference to FIG.
The principle of claim 2 will be described with reference to FIG.

  The embodiment of claim 1 will be described with reference to FIG. A silicon rubber intaglio (4) prepared in accordance with FIG. 3 is prepared and prepared (1). A functional material (5) is filled into the intaglio recess (11) with a blade (2) -1. Adhesive (6) is applied to the entire surface (3).

  Wait until the adhesive is semi-cured (4), press the cleaning roller (20) on the surface of the silicone rubber sheet (21), and all the material and adhesive on the intaglio plate (23) Is transferred and removed (5). After further drying of the adhesive in the recess, the substrate (8) is pressure-bonded (6), and the semi-solidified material and the adhesive in the recess are all transferred to the substrate (7). The powder is completely solidified by firing the substrate. As a result, a conductive wiring of 20 μm in height and 10 μm high in which silver powder was cured could be created.

  The embodiment of claim 2 will be described with reference to FIG. A silicon rubber intaglio having a predetermined depth is prepared ((1)). A functional material (5) is filled into the intaglio depression with a blade (18) ((2)). Adhesive A is applied to the entire surface (3).

  Waiting for the semi-curing of the adhesive (4), press the cleaning roller (20) made of the silicon rubber sheet (21) surface, and remove the adhesive from the material remaining on the intaglio plate (23). All of them are transferred and removed ((5)). After the material in the recess is dried, the material is further solidified (6), and the adhesive B (13) is applied with a blade (7).

  The substrate (8) is pressure-bonded, and the solidified material and the adhesive (A) and the adhesive (B) in the recess are all transferred to the substrate (9). The material is completely solidified by baking the substrate to form a pattern. As a result, a structure (partition plate) having a width of 180 μm and a height of 150 μm obtained by curing the NI powder could be created.

An embodiment of claim 3 will be described with reference to FIG. In the same process as in Example 2, a functional material mixed with a volatile solvent is filled into the intaglio recess with a blade ((2) -2). The subsequent steps are the same as in Example 2.

An embodiment of claim 4 is shown in FIG.
A plate cylinder (29) is provided, and a silicon rubber intaglio (4) is applied. Equipped with an adhesive supply mechanism (27), a functional material supply mechanism (28), and a cleaning roller (20) with a silicone rubber sheet (21) in contact with the intaglio, and a substrate (8) is placed on and in contact with it. A moving platen (30) is provided (1).

The functional material is supplied to the intaglio surface by the functional material supply mechanism, and the adhesive is supplied by the adhesive supply mechanism ((2)). The surface of the intaglio is cleaned with a cleaning roller ((3)). The intaglio image is transferred to the substrate (4).

A functional material is used on the substrate surface to attempt pattern formation without impairing the function.
A structure for obtaining the height and width is used to form a pattern on the substrate.
