Description

201250723 VI. Description of the Invention [Technical Fields of the Invention] The present invention is a detailed description of an electric multi-voice element consisting of a functional layer and a stack of electrodes disposed in a portion of the electrode. In order to electrically connect to the internal electrodes :;:: The contacts can be attached to the side of the stack. Such a composition is, for example, a multilayer resistance element, a multilayer resistance, or a plurality of: [Prior Art] In terms of the thickness of a functional layer in a conventional multilayer element, for example, the thickness of a dielectric layer in a multilayer capacitor is usually due to production It is difficult to keep the same. In addition, as far as the conventional production method is concerned, the electrical value of the multilayer component may be excessively deviated from the intended value due to fluctuations in thickness of the production layer. Accordingly, the present invention has been made in view of the above problems. [Invention] The object related to a specific embodiment is to detail the geometry of an electrical multilayer component, particularly the internal and external electrode configurations of an electrical multilayer component, and This has improved properties compared to multilayer components. This goal is achieved by the subject matter of the independent patent application. Further, advantageous embodiments and developments of -Hai et al* appear in the following description and accompanying drawings. The electrical properties of the multi-layer 70 pieces are related, in addition to some other factors, and in particular, to the geometric configuration of the internal electrodes. The thickness of the functional layer in the multilayer component 'e.g., the thickness of the dielectric layer in the multilayer capacitor is often difficult to maintain due to the production support. However, the thickness of the functional layer 95543 4 201250723 fluctuations affect the electrical value of the multilayer component 'e.g., the capacitance of the multilayer capacitor or the resistance of the multilayer resistive element', i.e., a PTC or nTc component. In the case of the conventional production method, in order to prevent the electrical value of the multilayer component from being excessively deviated from the predetermined desired value due to the thickness fluctuation of the functional layer by the production support, that is, in order to avoid a corresponding loose tolerance range, for example, pre-selection and subsequent formation are completed. A film of the functional layer of the component. As an alternative thereto, in the case of the conventional production method, a subsequent selection of the finished component is carried out, wherein the component whose electric rolling property is excessively deviated from the intended value is cleared. Moreover, in the case of conventional production methods, the electrical values of the components can then be adapted with so-called adjustments, such as by grinding or trimming portions of the multilayer component. The aforementioned possibility of combining to eliminate or at least reduce the disadvantages associated with thickness fluctuations of the functional layer by the production support is also a practice of conventional production methods. The inventors have discovered that with the internal electrode configuration described herein, the electrical values of the plurality of layers 70 (e.g., the resistance and/or capacitance of the multilayer component) can be maximized regardless of the thickness fluctuations of the functional layer. According to a particular embodiment, the electrical multilayer component is comprised of a stack having a plurality of functional layers and at least one first and one second internal electrode. The functional layers can be dielectric layers or conductive layers depending on whether the electrical multilayer component is implemented as a capacitor, varistor or thermistor. This layer determines the function of the component due to its own nature. For example, the functional layers can be plastic or ceramic layers. On the first day, in order to manufacture the multi-layered component, the functional days are stacked one by one to generate a stacking direction. The interface of adjacent functional layers determines the layer plane of the multi-layer element, which is arranged upward along the functional stacking direction - one ground 95543 201250723. The internal electrodes are arranged in the layer plane order. In the embodiment of the ligand, the first internal electrode is directly electrically connected to the first external contact disposed on the side of the stack, and is connected to the second external portion of the internal electrode disposed on the side of the stack.

Here, and below the 'direct conductive connection, it means that the internal electrical thinness is adjacent to the external contact and thus directly connected to the material contact. If the external contact is disposed on the side of the stack, the direct guiding money is connected to the side of the (four) electrode of the material contact. j _ According to another embodiment, the first and second internal electrodes have the same electrode length E. In this case, the electrode length E is a lateral extension of each of the first and second internal electrodes perpendicular to the stacking direction of the stack of the stack in the direction from the first to the first internal electrodes. Further, the first inner electrode and the second inner electrode have a distance H in the stacking direction of the layer. In particular, this means that the first and second internal electrodes are placed in two different layer planes perpendicular to the stacking direction of the stacked layers, where the two layer planes have a distance H from each other. Preferably, between the first and second internal electrodes, there may be only a plurality of functional layers having a thickness (four) function or a total thickness Η, and the first and the second internal electrodes The systems are directly adjacent to each other.

The special offer ' achieves this advantage by appropriately selecting the parameters Η, E' of the multilayer component. In the second embodiment, the first internal electrode is not disposed by the second and second modes. In other words, the first internal electrode does not cover the first inner portion in the imaginary projection of the cover i. Part of the area of the electrode. - 2: Another embodiment 'The first internal electrode portion overlaps the first internal electrode.

According to another specific embodiment, the multilayer component comprises to and/or a second internal electrode. In this case, the at least another: second internal electrode has an electrode length E. In this case, the electrode ==^ pole is perpendicular to the layer stacking direction by the first to the second inner electrode.

According to another embodiment, each of the free internal electrodes has a distance Η in the layer stacking direction from each of the free internal electrodes closest to the layer stack. In addition, each free internal electrode has a midpoint. In this case, the free inner = the midpoint of the electrode is the plane plane of the centauth f pole, and the virtual mirror at the midpoint 'the internal electrode will transform into the body. In addition, each free internal power = can be virtually divided into two equal-sized, equal-area, and length-_ 荨 portions, wherein the straight line runs through the midpoint of the free internal electrode.

In principle, the elements of the figure and the 95543 201250723-inch relationship between each other are not based on the actual ratio; instead, individual components, two U-pieces and regions 'may be exaggerated to illustrate their thickness or size to make (4) clearer And / or provide a better understanding. The diagram illustrates an electrical multi-section section according to an exemplary embodiment comprising a stack 8 of several functional layers 2 along the stacking direction s. In addition, on the eve of the present invention, a white inner row of internal electrodes, a fifth inner second layer of the inner layer of the red layer 70 includes a first electrode 6, which is disposed in the multilayer element 1 =: wherein the layer plane is composed of adjacent functional layers 2 The interface is decided.

The splicing joints 3, 4 are arranged on the two sides 91, 92 of the stack 8, and the alternative sides 91 ' sides 91, 92 are opposite sides. As its two in the figure, for example, it may also be the adjacent side of the stack 48. In the fur embodiment, the external contacts 3, 4 each cover the stack and may also be 92° as an alternative thereto, and the partial areas of the sides of the external contacts 3, 4 5 = or embodied on the stack 8 Edge-embracing fashi〇n :: cap-like (four) joints. For example, by dipping the object into a guide; Contact π = 2 includes: directly conductively connected to the first-outer (four)w and the second internal electrode 6 directly electrically conductively connected to the second outer peach.苐-, the second internal electrodes 5, 6 have the same electrode length ". In addition, the first internal electrode 5 and the second inner = 95543 12 201250723 pole 6 have a distance H in the layer stacking direction. The first internal electrode 5 and the second The internal electrodes 6 are directly adjacent to each other. In particular, this means that the functional layer 2 is alternatively disposed between the first and second internal electrodes 5, 6 and in direct contact with the first and second internal electrodes 5, 6. The plurality of functional layers 2 have no other internal electrodes. The stack 8 has a stack length b in a direction perpendicular to the layer stacking direction from the first to the second internal electrodes. The distance Η 'the stack length B and the electrode length e define an aspect ratio α = £ Β with a relative electrode length / = f, where amin = 2 〇 xe - lw and α _ = 15 〇χ '', and Wei is established. Figure 8 shows the multi-layer component A graph of electrical conductance 1/r or capacitance c as a function of layer thickness d of the functional layer. The internal electrodes are configured in a so-called "gap design" 501 (that is, in a non-overlapping manner and In the case of a conventional multilayer element in which the internal electrodes are arranged in a gap, in this case Next, curve A corresponds to a typical conductivity or a capacitance curve. In the case of ''gap design'), an electric field or current substantially parallel to the internal electrodes and the capacitance or resistance of such elements are substantially The layer thickness rises in proportion. Curve B shows a typical conductivity or capacitance characteristic of a conventional multilayer component in which the internal electrodes are arranged in a so-called "overlapping design" 5〇2 or T-type design "5"3, in the case of heavy 3 and then leaves, alternating The internally arranged internal electrodes are each heavy in the stacking direction. In the case of an overlapping design, an electric field or current is substantially formed in the stacking direction, that is, perpendicular to the internal electrodes. τ 95543 13 201250723 The series connection of two overlapping designs, the composition, the capacitance or conductivity of the elements decreases approximately as the layer thickness increases rather than proportionally. Therefore, in the conventional component design, the layer thickness variation directly affects the special secret. As a result, the addition of one branch causes the layer thickness to result in the same electrical value. In the multilayer component described herein, the superposition of the above effects of the conventional component can be achieved as shown by the curve z in Fig. 8. Due to the special internal electrode configuration, as described in conjunction with curve Mb, the layer thickness of the functional layer and the electrical value depend on each other. It can be easily seen that curve 2 is using two vertical dashed lines 9 8,9 9 has a substantially flat curve within the range of identification. This means that the resistance or capacitance of the multilayer A piece described herein is in this range irrelevant to the thickness fluctuation of the functional layer of the functional layer, in particular, The aspect ratio α of the above range is established. Fig. 6 is a graph showing the resistance of the element having different relative electrode lengths as a function of the aspect ratio β. The different resistance curves each have a more or less width. Flat range. Within this range, the element is relatively insensitive to thickness fluctuations of the functional layer, that is to say, within this range, the resistance of the element changes only a little when the thickness of the functional layer changes. Figure 7 illustrates the range Width, which is a graph showing the aspect ratio α as a function of the relative electrode length. Mathematically, the curves can be described by the above relationship of amin = 20xe - llx > flmax = 150x. 1 In the simplest form, the multilayer component described herein is illustrated as a basic component.
