    • PROBLEM TO BE SOLVED: To provide an electronic component without the missing or failure of plating wiring by surely forming a power feeding film for electric plating even when wiring patterns are densely arranged with the large number of layers. SOLUTION: This electronic component with the structure of lamination is configured of a substrate 1, wiring layers, insulating layers 9, 12, 15 and 18 and external connecting terminals, wherein the wiring layers and the insulating layers are alternately formed on the substrate 1, and only a portion of the insulating layer terminals 9, 12, 15 and 18 is formed with at least one inclined structure for electric plating power supply. The number of the wiring layers and the insulating layers is piled up, and even when the ends of the insulating layers are shaped so as to be steep, a power supply line can be secured. As a result, even when the number of lamination is increased, the wiring layers can be surely formed, and the electronic component without wiring missing can be provided. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:即使当布线图案以大量层压密布置时,通过确保形成用于电镀的供电膜来提供电子部件而不会出现电镀布线的缺失或故障。 解决方案:具有层叠结构的电子部件由基板1,布线层,绝缘层9,12,15和18以及外部连接端子构成,其中布线层和绝缘层交替地形成在 基板1,并且只有一部分绝缘层端子9,12,15和18形成有用于电镀电源的至少一个倾斜结构。 堆叠布线层和绝缘层的数量,即使当绝缘层的端部成形为陡峭时,也可以确保电源线。 结果,即使当层叠数量增加时,可以可靠地形成布线层,并且可以提供没有布线的电子部件。 版权所有(C)2005,JPO&NCIPI
