させてスクリーン印刷を行う。 As shown in Fig. 1, the conventional screen printing method involves placing a printing material 2 such as carbon paste on a screen 1 on which a desired printing pattern has been provided, and applying a print material 2 to the acute angle formed by the side surface of a squeegee 3 and the screen surface. Screen printing is performed by placing the printing material 2 and moving the squeegee 3.

であつた。 This screen printing method is the most popular and can sufficiently achieve the printing precision required for hybrid integrated circuits. However, for highly accurate control of the resistance value of the resistor using carbon paste, there is a third method.
As shown by the dotted line in the figure, when looking at the relationship between the angle of the squeegee 3 and the film thickness, there are considerable variations. Therefore, it has been difficult to achieve precise control of printed film thickness and printing of ultrafine patterns by screen printing.

明の一実施例を詳述する。 The present invention has been made in view of this point, and is intended to realize screen printing that greatly improves the conventional drawbacks. An embodiment of the present invention will be described in detail below with reference to FIGS. 2 and 3.

け、スキージーの変形を防止する。 The screen printing method according to the present invention has the greatest feature in using the tip end surface of the squeegee 13. That is, as shown in FIG. 2, a printing material 12 such as carbon paste is placed on a screen 11 on which a desired printing pattern has been formed, and a squeegee 13 is placed on the screen 11.
The printing material 12 is stored at the acute angle formed by the tip surface and the screen surface, and the squeegee 13 is moved to perform screen printing. If necessary, a reinforcing plate 14 is provided on the upper side of the squeegee 13 as shown in the figure to prevent the squeegee from deforming.

角度θが同一である場合は本発明の方が膜厚が厚
くなる。しかし本発明では角度θを変えることで
従来と同じ膜厚の印刷を行なえる。 According to the above method, as shown by the solid line in Figure 3,
Printing film thickness can be controlled accurately over a wider range than before. The reason for this is not clear, but
In the conventional method, the printing material 12 is printed by the force of pulling the squeegee 13, whereas the method of the present invention prints the printing material 12 by the force of pushing the squeegee 13, so that the printing material 12 is uniformly pushed out from the screen 11. It is believed that there is. Therefore, in the present invention, when the angle θ between the squeegee 13 and the screen surface is the same, the film thickness is thicker in the present invention than in the conventional case. However, in the present invention, by changing the angle θ, printing can be performed with the same film thickness as in the past.
本発明を用いる利点は種々あるが、第１に前述
した角度θの切り換えにより広い範囲での膜厚の
コントロールができる。本実施例では約14〜30μ
の間でコントロール可能である。この結果抵抗体
の印刷に適用すれば抵抗値の制御も簡単に行なえ
る。 There are various advantages of using the present invention, but firstly, the film thickness can be controlled over a wide range by switching the angle θ mentioned above. In this example, approximately 14 to 30μ
It is possible to control between As a result, when applied to printing resistors, resistance values can be easily controlled.
第２に本発明ではスキージー１３の移動距離を

短縮を図れ、使用印刷材料の量を減少できる。ま
た移動距離が短かいので印刷の安定性も確保でき
る。 Second, according to the present invention, the moving distance of the squeegee 13 can be made shorter than in the past. The reason for this is that the conventional method prints using a pulling force, so it is necessary to move the squeegee 13 until it is sufficiently separated from the desired pattern. As a result, the present invention can shorten printing time and reduce the amount of printing material used. Furthermore, since the moving distance is short, printing stability can be ensured.
第３に本発明は膜厚を一定にコントロールでき
るので、導電路等のレジスト印刷のとき隣接する
導電路の間隔を狭くでき、約70μ間隔のフアイン
パターンの印刷も可能である。 Thirdly, in the present invention, since the film thickness can be controlled to be constant, the distance between adjacent conductive paths can be narrowed when resist printing conductive paths, etc., and it is also possible to print fine patterns with an interval of about 70 μm.
