Description
【考案の詳細な説明】 本考案は印刷抵抗体構造の改良に関する。[Detailed explanation of the idea] The present invention relates to improvements in printed resistor structures.
従来の印刷抵抗体構造は第１図および第２図に示す如く
、絶縁基板１上に設けられた銅箔より成る導電路２と導
電路２にその一端を重畳させて印刷した導電ペースト層
３と導電ペースト層３にその一端を重畳させて印刷した
抵抗体塗料による抵抗体４より構成されている。As shown in FIGS. 1 and 2, the conventional printed resistor structure includes a conductive path 2 made of copper foil provided on an insulating substrate 1 and a conductive paste layer 3 printed with one end overlapping the conductive path 2. It consists of a resistor 4 made of a resistor paint and printed with one end superimposed on a conductive paste layer 3.
斯る印刷抵抗体構造では導電路２と重畳する導電ペース
ト層３で銅箔の段差切れを発生することがあった。In such a printed resistor structure, a step breakage of the copper foil may occur in the conductive paste layer 3 overlapping with the conductive path 2.
特に印刷抵抗体の方向と印刷方向がほぼ一致したとき導
電路２端部での印刷膜厚の減少が発生して段差切れを発
生するものと考えられる。In particular, it is considered that when the direction of the printed resistor and the printing direction almost match, the thickness of the printed film at the end of the conductive path 2 decreases, causing the step breakage.
本考案は新患に鑑みてなされ、従来の欠点を除去する印
刷抵抗体構造を実現するものであり、第３図乃至第５図
を参照して本考案の実施例を詳述する。The present invention has been developed in view of the new disease, and aims to realize a printed resistor structure that eliminates the drawbacks of the conventional method.Examples of the present invention will be described in detail with reference to FIGS. 3 to 5.
本考案に依る印刷抵抗体構造は従来のものと同様に第３
図に示す如く、絶縁基板１上に設けられた銅箔より成る
導電路２と導電路２にその一端を重畳させて印刷した導

。The printed resistor structure according to the present invention has a third
As shown in the figure, a conductive path 2 made of copper foil provided on an insulating substrate 1, a conductive paste layer 3 printed with one end overlapping the conductive path 2, and a conductive paste layer 3 printed with one end overlapping the conductive paste layer 3. The resistor 4 is made of resistor paint.
本考案の特徴は導電ペースト層３と重畳する導電路２端
部の形状にある。The feature of the present invention lies in the shape of the end portion of the conductive path 2 overlapping with the conductive paste layer 3.
即ち部上の導電路２端部を第３図の如く導電ペースト層
３の印刷方向に対して傾斜した辺とする。That is, the end portion of the conductive path 2 on the portion is made to be a side inclined with respect to the printing direction of the conductive paste layer 3 as shown in FIG.
この結果、印刷を行うスキージ−は導電路２の巾を１傾
斜をθとすると導電路２端部とＩｃｏｓθの間接するこ
とになり、従来の様に導電路２端部の段差で急に落ち込
むことを防止でき、導電路２端部での導電ペースト３の
印刷膜厚を十分に確保でき段差切れを防げるのである。As a result, if the width of the conductive path 2 is 1 inclination as θ, the squeegee that performs printing will be in contact with the end of the conductive path 2 and I cos θ, and unlike the conventional method, the squeegee will suddenly drop at the step at the end of the conductive path 2. This makes it possible to ensure a sufficient printing film thickness of the conductive paste 3 at the ends of the conductive path 2, thereby preventing step breakage.
第４図および第５図は本考案の他の実施例を示す。Figures 4 and 5 show other embodiments of the invention.
第４図では導電路２端部にＶ字状の溝５を印刷方向にく
ぼませて形成している。In FIG. 4, a V-shaped groove 5 is formed at the end of the conductive path 2 by recessing it in the printing direction.
また、第５図では導電路２端部に切り込まれた溝６を印
刷方向にくぼませて形成している。Further, in FIG. 5, the groove 6 cut into the end of the conductive path 2 is formed by being depressed in the printing direction.
部上した溝５，６を設けるとスキージ−が導電路２端部
に達するまで急に落ち込まないので、溝５，６の部分に
厚い膜厚の導電ペースト層３を印刷できるので段差切れ
を防止できる。By providing raised grooves 5 and 6, the squeegee does not fall suddenly until it reaches the end of the conductive path 2, so a thick conductive paste layer 3 can be printed on the grooves 5 and 6, thereby preventing step cuts. can.
以上に詳述した如く本考案に依れば導電路端部に印刷方
向に対して傾斜した辺あるいは印刷方向に対してくぼん
だ溝を設けるだけで導電ペースト層の段差切れを容易に
防止できミ印刷方向に影響を受けない印刷抵抗体を実現
できる。As detailed above, according to the present invention, it is possible to easily prevent step breakage of the conductive paste layer by simply providing a side inclined to the printing direction or a groove concave to the printing direction at the end of the conductive path. It is possible to realize a printed resistor that is not affected by the printing direction.
