Abstract

PROBLEM TO BE SOLVED: To restrain a thickness of an outer periphery of a printing pattern transferred to a body to be transferred from becoming irregular, by setting an aperture area of each cell at an outer peripheral part to be smaller than an aperture area of each cell at an inner part in a printing pattern of a base body. SOLUTION: Among a plurality of cells 12 to be provided on a printing pattern 4, each cell 12a to be provided at an outer peripheral part is made to have an aperture area smaller than that of each cell 12 at an inner part and its depth is also made to be shallower than that of the cell 12 at the inner part. While the inner cell 12 is made to be square, each rectangular corner part at the outer periphery is made to have a small square. In a printing pattern 11 formed by using the printing pattern 4, the thickness of the outer peripheral part becomes substantially uniform over the whole periphery.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component manufacturing apparatus using a printing method.

[0002]

2. Description of the Related Art In an electronic component manufacturing apparatus using a printing method, a plurality of printing patterns 1 as shown in FIG.

The print pattern 1 is formed by aligning a plurality of cells 2 as shown in FIGS.

After the printing paint is supplied into the cell 2, the transfer material is pressed against the upper surface of the printing material by a pressing roller to transfer the printing paint in the cell 2 to the lower surface of the transfer material.

[0005]

A problem in the above-mentioned conventional example is that the thickness of the outer periphery of the print pattern transferred to the lower surface of the transfer target becomes uneven.

That is, the print pattern 1 on the substrate is determined by the size specification of the product to be manufactured, and the cells 2 of a predetermined size are appropriately arranged in the print pattern 1 from one side. As shown in FIGS. 12 to 14, a small cell 2a was conveniently formed in a place left on the other side. Therefore, on the outer periphery of the print pattern 1, for example, large cells 2 are provided on the upper side and the right side in FIG.
A small cell 2a is provided on the lower side and the left side, and as a result, the outer peripheral thickness of the print pattern transferred to the transfer target becomes uneven.

[0007] Therefore, an object of the present invention is to prevent the thickness of the outer periphery of the print pattern transferred to the transfer body from becoming uneven.

[0008]

In order to achieve this object, according to the present invention, in the printed pattern of the substrate, the opening area of cells in the outer peripheral portion is smaller than the opening area of inner cells. Is.

[0009]

According to the above means, the opening area of the cells in the outer peripheral portion of the print pattern is set to be smaller than the opening area of the inner cells in advance so as to make the cell sizes in the outer peripheral portion non-uniform. Therefore, it is possible to prevent the thickness of the outer peripheral portion of the print pattern transferred to the transfer target from becoming uneven.

[0010]

4 and 5, reference numeral 3 denotes an iron-made cylindrical transfer roller used as an example of a substrate, and a plurality of print patterns 4 are provided on the outer peripheral surface thereof. The lower part of the transfer roller 3 is provided so as to be immersed in the printing paint 6 in the container 5, and when the transfer roller 3 is rotated as shown by the arrow in FIG.
It is designed to be filled inside. 7 is a doctor blade, which is an extra printing paint 6 on the outer periphery of the transfer roller 3.
It is designed to scrape off. On the other hand, the transferred body 8 is moved above the transfer roller 3. That is, the transferred material 8 used in this embodiment is a ceramic green sheet, which is polymerized and integrated with the film 9, and while pressing the polymer with the upper pressing roller 10 and the transfer roller 3, the right side of FIG. It is designed to be moved toward. At this time, as shown in FIG. 4, the print paint 6 in the print pattern 4 is transferred to the lower surface of the transfer target 8. The printing paint 6 used in this embodiment is a conductive paint, and after being transferred to the transferred body 8, the printing paint 6 is polymerized and fired like a ceramic capacitor, whereby the printing pattern 11 becomes an electrode. .

What is important in the electrode of such an electronic component is that the thickness of its outer circumference is uniform over the entire circumference. That is, when the thickness of the outer peripheral portion of the electrode becomes uneven, a portion where the electrical characteristics are locally deteriorated is formed, which makes the electrical characteristics of the electronic component as a whole unstable. Therefore, in this embodiment, as shown in FIGS. 1 to 3, among the plurality of cells 12 provided in the print pattern 4, the cells 12a provided in the outer peripheral portion have an opening area smaller than that of the inner cells 12 in advance. , Its depth is also shallower than the inner cell 12. Although the inner cells 12 are basically square, as shown in FIG. 1, the outer left, right, upper and lower sides are rectangular and the corners are small squares. Therefore, if the print pattern 11 shown in FIG. 4 is formed by using the print pattern 4, the thickness of the outer peripheral portion of the print pattern 11 becomes substantially uniform over the entire circumference.

The small cells 12a on the outer circumference and the large cells 12 on the inner side are also formed by matching, and the distance between them is the same as that between the large cells 12.

FIGS. 6 to 8 show another embodiment of the present invention. In this embodiment, the large cell 13 is tilted by 45 degrees and the small outer cell 13a is an isosceles triangle of half thereof. Is.

Next, FIGS. 9 to 11 show still another embodiment, in which a large inner cell 14 and a small inner cell 1 are used.
4a is a pyramid-shaped quadrangular pyramid.

Reference numeral 15 in FIGS. 1 to 11 is the print pattern 4.
It is a frame formed in a groove shape on the outer periphery of.

[0016]

As described above, according to the present invention, a substrate having a print pattern composed of an assembly of a plurality of cells, a paint supplying means for supplying a print paint into the cells of the base, and a print pattern of the substrate. A moving means for moving the transferred body upward, and a pressing means for pressing the transferred body moved on the print pattern by the moving means toward the substrate side,
The printed pattern of the substrate is such that the opening area of the cells in the outer peripheral portion is smaller than the opening area of the inner cells.

With the above means, the opening area of the cells in the outer peripheral portion of the print pattern is set to be smaller than the opening area of the inner cells in advance so that the cell size in the outer peripheral portion is made uniform. Therefore, it is possible to prevent the thickness of the outer peripheral portion of the print pattern transferred to the transfer target from becoming uneven.
