In the prior art, electronic products are becoming lighter, thinner, shorter, smaller, and more versatile. As a result, electronic passive components have developed toward arrays or modularization. Therefore, in a multilayer chip filter component, it is often necessary to combine several inductors and The capacitor is integrated into a whole through circuit design and multi-layer chip assembly manufacturing process, and becomes a multi-layer inductor-capacitor module. -The general traditional manufacturing method divides the element into two parts,-the part of the inductive material 'includes all the inductors in the module ... the part of the capacitive material' includes all the capacitors; that is, all inductive circuits are designed in magnetic materials Layer 'all capacitor lines are designed in a dielectric material layer, the two are fired separately and then bonded' or the two are stacked and fired together. Due to the difference in shrinkage between magnetic materials and dielectric materials, the traditional manufacturing method is easy to cause stress concentration at the interface between the inductive material and the capacitive material due to shrinkage matching, which makes the components prone to surface curvature and cracking. In addition, due to the miniaturization of the components and the high integration of the lines in the components, the components are likely to interfere with each other and cause crosstalk (㈣ss theory). The previous technology for manufacturing multilayer inductor and capacitor modules is also Japanese Patent No. 6-325977, in which the inductor part and the capacitor part are sintered and then bonded. US patent_4111 discloses a multilayer inductor-capacitor module formed by co-firing both an inductor portion and a capacitor portion 200522107. Japanese patent JP2003-051729 discloses a multilayer inductor-capacitor module composed of a stack of inductor layers and a stack of capacitor layers. U.S. Patent No. 5,558,740 discloses an inductor array 'with a low-permeability insulation layer that separates the element into two parts to reduce magnetic line-to-line coupling between the inductors. U.S. Patent No. 5,023,578 discloses a three-terminal capacitor-type filter array whose circuit layout is mainly on two planes, one plane is a line for each signal line, and the other plane is a common electrode. SUMMARY OF THE INVENTION The purpose of the present invention is to propose a multilayer IX 泸, wave module, which uses a structure in which the inductor layer and the capacitor layer are dispersed in the thickness direction to separate the capacitor layer and the capacitor layer to make crosstalk between the inductors ( cr0sstalk). The purpose of this paper is to propose a multi-layer LC filter module, so that the material with the rate and the dielectric constant can be used as the multi-layer UC mode, and the inductor layer and the capacitor should be split. The warpage and breakage of components in the m-specialized control method of the present invention is a multilayer LC filter module in the United States. The inductor circuit and the lightning circuit are included in the United States. The layout design can make use of the overall area of the component, so that the accuracy of the area utilization process can be better controlled. A further object of the present invention is a method for preparing. The structure of the multilayer mind wave module is to achieve the above-mentioned objective layer LC filter module of the present invention, which includes a table constructed by one month-a kind of dielectric constant between 4 7-yes-a permeability between 5 and 1300 and I. to 2750 structural materials; and inductive lines and capacitor electrodes formed on different horizontal planes within the material of the structure 200522107, among which. The sense lines and the capacitor electrodes alternate with each other in the vertical direction. It is preferable that the inductive line and the capacitive electrode culvert have a strictly full horizontal area for the time being. $ 贝 Preferably, in this Xiao 胄 # t (Ti〇2) x (M〇.Fe2〇3) y, where x + y = 1, 〇gx $ ,, ~~ ~ M is Mη, Ni,

Preferably, the surface of the inductive circuit is substantially entirely of gold, silver and silver, and the inductive circuit and the capacitor electrode are independent of each other or any combination thereof. Embodiment The LC filter module utilizes an inductor layer and an electric current. The present invention proposes a multilayer structure of 200522107. The capacitor layer is dispersed in the thickness direction. As shown in the figure, the inductor layer 10 and the capacitor layer 20 are spaced apart, compared with the traditional The manufacturing method integrates all the inductors in the magnetic material layer, so the crosstalk between the inductors of the present invention will be greatly reduced, which is very close to zero. The materials of the inductor layer and the capacitor layer of the present invention use the same series of materials (but not necessarily completely the same) having both magnetic permeability and dielectric constant. The magnetic permeability is between 5 and 1300, and the dielectric constant is between 4.7 and 2750. , So that there is no sintering shrinkage matching problem between each inductance layer and the capacitor layer, which reduces its internal stress. The circuit layout of each inductance layer and capacitor layer of the present invention can use the full area of its layer structure to improve the area utilization rate and the flexibility of the circuit layout. The present invention proposes a multilayer LC filter module, which is composed of a plurality of inductors and a plurality of capacitors. The structure in which the inductor layer and the capacitor layer are dispersed in the thickness direction is used. The inductor layer and the capacitor layer are separated. For example, the inductor circuit and the capacitor electrode are printed on the surface of the inductor layer and the capacitor layer according to the design. If the lamination method is the traditional method, due to the difference in shrinkage of the two materials, it is easy to cause stress concentration on the interface and cause surface bending and cracking of the component. If the lamination method is like the dispersed structure of the present invention, and the raw material of the inductor layer and the capacitor layer uses a material having both magnetic permeability and dielectric constant, there is no stress problem of shrinkage matching. In addition, the terminal electrode or the internal via also has a dislodging effect on the component, which can solve the problem of fun and crack of the component and improve the reliability of the component. With the structure of the present invention, the electrode design of the capacitor layer can make full use of the entire area of the element 'to make the circuit layout of the inductor and capacitor more flexible. As an example, as shown in FIG. 2a, if the size is divided into four 1608 sizes and the layout is designed in the same layer of 200522107, the electrode area of each electrode can be designed to be 1.2 mm x 0.4 mm. If the overall surface is used as shown in Figure 2b, the electrode area can be designed to be 2.8 mm X 1.2 mm; the area of the electrode is 7 times that of the former. Therefore, in order to obtain the same capacitance as that obtained by decorating the board with a whole area, the layout of 4 divisions must use 7 sheets of raw embryos'. Only 4 sheets of raw embryos are required to use the structure of this creation. The circuit layout of the inductor layer also has the same situation. The size of 3 21 6 is also taken as an example. The line can be designed as a straight ^ meander line or a spiral single or multi-layer design. The right side is 4 Ι608 size, you must increase the number of turns of the inductor to obtain the same Qimen's inductance, increasing the complexity of the process. Examples and Comparative Examples The element size was 3216. Inductive lines are printed with a single layer of polysilicon screened by silver plastic with a line width of 0.1 mm. The raw embryos used (Ti〇2) 〇, (Ni〇, 2Cu〇.28Zn0.6.Fe2〇3) 〇9 # ^ = u = 50 and the number of k 1700. The inductive line u and the capacitive electrode 2i are printed on the surface of the green embryo according to the design, respectively. As shown in Figure & 1 as shown in Figure 3a, the inductor layered embryo and the electric layered embryo are superimposed to form a _ structure, and then the structure is sintered in _ C '2 hours to form a laminate of the invention The lc filter module has a structure in which the inductance layer 10 and the capacitance layer 20 are alternately spaced. Figure 3b shows the LC LC module of the comparative example. The manufacturing method is the same as that of the embodiment except that the stacking method is different. The inter-frequency electromagnetic field simulation was used to evaluate the crosstalk between the inductors of the two laminated LC filter modules of the embodiment and the comparative example. The simulation results are as follows: 200522107 ^ —----- Crosstalk (dB) Example ---- ~ ---_____ < -100 Comparative Example ------- -1 0 ~, 2 0 Schematic Brief Description FIG. 1 shows a schematic diagram of a multilayer LC filter module according to the present invention.
