摘要： PROBLEM TO BE SOLVED: To provide lamination components which can reduce the packaging height from the lower surface of a printed circuit board to the height of the lamination components and the packaging structure of the lamination components, even when insulation is required on the lower surface of the printed circuit substrate.
SOLUTION: The project 1a of the center part of the lamination 1 of the lamination component 10 is dropped into the hole 5 of the printed circuit board 4, the electrode 2 formed in both the ends of the lamination 1 and on its front surface is laid in the printed circuit board 4, and the electrode 2 and the printed circuit board 4 are connected electrically and mechanically by a solder 6. Since the project 1a of the lamination 1 is dropped into the hole 5 of the printed circuit board 4, the packaging height from the lower surfaced 4 of the printed circuit board becomes 1 mm in thickness of the lamination components 10 (lamination 1), and the flat structure can be achieved. Since the electrode is not exposed from the lower surface of the printed circuit board 4, the insulation of the lower surface of the printed circuit board 4 can be assured.

摘要翻译：要解决的问题：为了提供能够将包装高度从印刷电路板的下表面降低到层压部件的高度和层压部件的包装结构的层压部件，即使在需要绝缘的情况下印刷电路基板的下表面。解决方案：层压部件10的层压体1的中心部分的突出部1a落入印刷电路板4的孔5中，形成在层压体1的两端的电极2和其前面表面被放置在印刷电路板4中，并且电极2和印刷电路板4通过焊料6电连接和机械连接。由于层压体1的突出部1a落入印刷电路板4的孔5中，印刷电路板的下表面4的封装高度变为层叠部件10（层叠体1）的1mm厚，能够实现平坦的结构。由于电极不从印刷电路板4的下表面露出，所以可以确保印刷电路板4的下表面的绝缘。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminated substrate capable of simplifying a process and obtaining the high degree of freedom in electrode design without being affected by the thickness of an electrode, and enabled in flattening a surface. SOLUTION: A desired wiring pattern 11 of silver paste is formed on a green sheet 12 by screen printing (e). Here, a pattern to be an electrode is also printed in addition to a pattern to be a coil. A plurality of green sheets 12 are sequentially subjected to lamination press working to form a laminate 32 (f). The laminate 32 is divided in elements (g), and then baked (h). At this time, on a laminated substrate 1, a surface electrode 2, a bottom electrode 3, and a side electrode 4 are already formed with surfaces flush with all the electrodes. The electrodes 2, 3, and 4 are plated (i). The laminated substrate 1 thus manufactured is mounted with electronic components and resin-molded, to manufacture a composite circuit element.

摘要： PROBLEM TO BE SOLVED: To provide a multilayer inductor in which the problem of fringing can be solved, eddy current loss is not increased and a stable magnetic property is acquired, and a circuit board having the multilayer inductor built-in.
SOLUTION: A coil pattern 2 comprising Ag and a nonmagnetic substance 3 comprising ZrO
2 for forming a magnetic gap exist between magnetic substances 1 comprising NiCuZn ferrite. The width of the coil pattern 2 in a magnetic gap layer 11 having the coil pattern 2 and the nonmagnetic substance 3 is narrower than that of the coil pattern 2 in a magnetic substance 12 having only the coil pattern 2. Since the width of the coil pattern 2 in the magnetic gap layer 11 is made narrower and the width of the nonmagnetic substance 3 is made wider in this structure, even when a magnetic flux is leaked from a center leg, the leakage magnetic flux does not interlink with the coil pattern 2 (arrow), so that generation of the eddy current loss is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a stacked inductor that reduces the influence of stress given from a nonmagnetic body as a magnetic gap, and improves DC superposition characteristics, while suppressing deterioration of a magnetic property of a magnetic body, and a stacked substrate incorporating the stacked inductor.
SOLUTION: There are coil patterns 2 made of Ag and nonmagnetic bodies 3 comprising a material, obtained by adding glass into stabilized ZrO
2 for forming a magnetic gap, which are sandwiched by a magnetic body 1 containing a Li-Cu-Zn based ferrite. Since Li-based ferrite has high stress resistance, as compared with conventional Ni-based ferrites, the magnetic properties of the magnetic body 1 are less likely to be affected by stresses from the nonmagnetic body 3 produced during the sintering.
