産業上の利用分野
本発明は、厚膜抵抗体の印刷に使用する描画用ノズルを
有する厚膜抵抗印刷装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a thick film resistor printing apparatus having a drawing nozzle used for printing thick film resistors.
従来の技術
従来、この種の装置において、スタイラスの取付けは印
刷方向に対し、ノズルの前側に取付けられていた。BACKGROUND OF THE INVENTION Conventionally, in this type of apparatus, the stylus has been mounted on the front side of the nozzle with respect to the printing direction.

な状態にはなり得ない。Problems to be Solved by the Invention However, in this stylus mounting structure, a thick film conductor is used to connect the resistor as shown in Figure 1, and the stylus moves on this conductor as shown in Figure 2. Therefore, the height of the thick film conductor affects the height of the thick film conductor during drawing, and the unevenness of the resistor film thickness becomes large, making it difficult to obtain a stable resistance value. Since the stylus is attached to the front side of the nozzle, the nozzle tip follows the unevenness of the substrate and thick film conductor, and the film thickness of the resistor becomes as shown in Figure 3. It cannot be in the state shown in the figure.

。Function: With the above structure, the stylus always moves over the substrate, so that the film thickness can be kept constant. Also, even on thick film conductors, the stylus and nozzle move in the same position as a pair in the printing direction, so
As shown in FIG. 1, the same film thickness t as on the substrate can be obtained.

凹凸が大きく、第１図の形状とは大きく異なる。FIG. 1 is a cross-sectional view of a connecting surface between a thick film resistor 3 and a thick film conductor 4. As shown in FIG. FIG. 2 is a state diagram during drawing type printing, in which the stylus 2 attached to the front side of the nozzle 1 is moving over the thick film conductor 4. When the stylus 2 rides on the conductor 4, the film thickness of the resistor 3 becomes larger than the target film thickness t, and a step 6 occurs. Third
The figure is a cross-sectional view of the resistor 3 drawn in the state shown in FIG. 2, which has large irregularities and is greatly different from the shape shown in FIG. 1.
