Abstract
The utility model provides an inclined-plane single-layer ceramic capacitor. The inclined-plane single-layer ceramic capacitor is provided with a ceramic dielectric layer, an upper electrode layer and a lower electrode layer, wherein the upper electrode layer is adhered to the upper end face of the ceramic dielectric layer, the lower electrode layer is adhered to the lower end face of the ceramic dielectric layer, and the area of the upper electrode layer is smaller than that of the lower electrode layer. The ceramic dielectric layer, the upper electrode layer and the lower electrode layer adopt inclined-plane design, a route of conducting slurry or soldering paste from the lower electrode layer and the upper electrode layer is enlarged, and accordingly the capacitor short circuit caused in the assembling process of the single-layer ceramic capacitor is avoided or prevented.
Description
Technical field
The utility model relates to a kind of inclined-plane single-layer ceramic capacitor, is used for being coupled at circuit, filtering and every directly.
Background technology
At present, a large amount of single-layer ceramic capacitors that use of industry, its basic structure is that ceramic plane is vertical with electrode surface, such as publication number be CN 1601673.A patent disclosure be a kind of ceramic plane single-layer ceramic capacitor vertical with electrode surface.Because ceramic plane is very thin, generally only has 0.076-0.254mm, therefore, when assembling, electrocondution slurry or soldering paste are easy to overflow across the ceramic layer height, turn up to be connected with the pole-face that powers on, thereby cause capacitor short-circuit, obviously, traditional ceramic plane single-layer ceramic capacitor vertical with electrode surface causes capacitor short-circuit easily when assembling be undisputable fact, therefore is necessary to improve.
The utility model content
The technical problem that the utility model solves: provide a kind of inclined-plane single-layer ceramic capacitor, the capacitor short-circuit problem that can effectively avoid or prevent the single-layer ceramic capacitor in assembling process, to occur.
The technical solution adopted in the utility model: a kind of inclined-plane single-layer ceramic capacitor, have ceramic dielectric layer and be attached to the upper electrode layer of ceramic dielectric layer upper surface and the lower electrode layer of its lower surface, the area of described upper electrode layer is less than the area of lower electrode layer.
Wherein, the edge line of the edge line of described ceramic dielectric layer and upper electrode layer and lower electrode layer is an oblique line, and the angle between the end face of ceramic dielectric layer and upper electrode layer and the lower electrode layer is 0-90 °.
Further, the lower surface of the angle between the upper surface of described ceramic dielectric layer and the upper electrode layer and ceramic dielectric layer equates with angle between the lower electrode layer or is unequal.
The utility model is compared with prior art because ceramic dielectric layer and upper/lower electrode layer all adopt inclined design, widened electrocondution slurry or soldering paste from the lower electrode layer to the upper electrode layer between the path, thereby avoid or prevented that the single-layer ceramic capacitor causes in assembling process the capacitor short-circuit problem.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of inclined-plane single-layer ceramic capacitor has ceramic dielectric layer 1 and is attached to the upper electrode layer 2 of ceramic dielectric layer 1 upper surface and the lower electrode layer 3 of its lower surface, and the area of described upper electrode layer 2 is less than the area of lower electrode layer 3.Concrete, the edge line of the edge line of described ceramic dielectric layer 1 and upper electrode layer 2 and lower electrode layer 3 is an oblique line, 2 the path from lower electrode layer 3 to upper electrode layer to have widened electrocondution slurry or soldering paste, the short circuit problem of avoiding or having prevented the single-layer ceramic capacitor to cause in assembling process.And the angle between the end face of ceramic dielectric layer 1 and upper electrode layer 2 and the lower electrode layer 3 is 0-90 °, and the angle between the upper surface of described ceramic dielectric layer 1 and the upper electrode layer 2 and the lower surface of ceramic dielectric layer 1 equate with angle between the lower electrode layer 3 or be unequal.
First at up and down two end face coating upper electrode layers 2 and the lower electrode layer 3 of ceramic dielectric layer 1, upper electrode layer 2 and lower electrode layer 3 can be single-layer metals, such as silver, copper, nickel, tin or gold etc., it also can be multiple layer metal, such as titanium tungsten/gold, titanium tungsten/nickel/gold/, titanium/copper/gold etc., the method of coating upper electrode layer 2 and lower electrode layer 3 can be print process, sputtering method, evaporation, chemical plating or galvanoplastic etc.Then ceramic dielectric layer 1 is carried out cutting-up, guarantee during cutting-up that the plane at ceramic dielectric layer 1 place becomes 30 ° angle all the time with putting down into of cutting-up cutter place.After cutting-up finishes, just obtain the inclined-plane single-layer ceramic capacitor of ceramic dielectric layer 1 and the angle of 3 one-tenth 30 ° of lower electrode layers.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalences of being done with the described content of the utility model claim change, all should be included within the utility model claim scope.
