Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the laminated electronic component mainly includes an inner electrode 11 and an outer electrode electrically connected to the inner electrode 11, in the process of manufacturing the inner electrode 11, a dielectric material in a fluid state obtained by material preparation is cast to obtain a membrane 11b1, a conductive material is printed on the membrane 11b1 as an electrode sheet 11a1 to form an inner electrode layer 111, and then multiple layers of inner electrode layers 111 formed by the membrane 11b1 and the electrode sheet 11a1 are laminated to form a bar 1, that is, the bar 1 is formed by laminating a plurality of (usually thousands of) inner electrode layers 111, in other words, the electrode sheet 11a1 is sandwiched between a plurality of membranes 11b1, the electrode sheet 11a1 on each membrane 11b1 is formed into a square or rectangular conductive sheet structure uniformly distributed on the membrane 11b1 mainly through a screen printing process, and the plurality of electrode sheets 11a1 on the same membrane 11b1 are distributed in a matrix at intervals.
Referring to fig. 2, fig. 2 is a top view of a bar block 1 formed by laminating a plurality of internal electrode layers 111, and the upper surface of the uppermost film sheet of the bar block 1 is generally free of electrode sheets, so in the top view of the bar block 1 shown in fig. 2, a conductive portion 11a formed by laminating electrode sheets 11a1 is indicated by a dotted line, and it should be noted that the conductive portion 11a indicates a portion of the bar block 1 formed by laminating a plurality of electrode sheets 11a1, and as can be seen in fig. 2, a plurality of conductive portions 11a are formed on one bar block 1, and the conductive portions 11a are cut according to a cutting line 21 designed according to the product requirement to form a single independent internal electrode 11.
The cutting line 21 is generally marked by an automatic device or a person after the lamination is completed, so that the cutting device can recognize and cut the bar 1 along the cutting line 21, thereby dividing the bar 1 into a plurality of internal electrodes 11, and the cutting line 21 is generally marked 31 on the upper surface of the bar 1 and forms a cutting line marking area 20 around the outermost periphery of the bar 1; the inner electrode cutting area 10 to be cut is formed inside the cutting line marking area 20, and the inner electrode cutting area 10 is an area where a plurality of conductive parts 11a are located, and the bar 1 is cut along the cutting line 21 by cutting equipment to obtain a plurality of small inner electrodes 11. In the internal electrode 11, the electrode pieces 11a1 between the upper and lower adjacent internal electrode layers 111 are distributed in a staggered manner.
According to the research, in the process of the part of laminated electronic components, due to the process error, a certain proportion of the inner electrode layers 111 deviate to cause deviation abnormality, and the appearance, the electrical property and the reliability of the inner electrode 11 with the deviation abnormality are larger than those of normal components, so that the qualification rate of the components is lower, and even the application end cannot use.
Referring to fig. 2 again, for example, the inner electrode 11 is formed by cutting the block 1 along the cutting lines 21a, 21b, 21c, 21d, and the perspective view of the inner electrode 11 is shown in fig. 3, in which the conductive portion 11a formed by stacking the plurality of electrode sheets 11a1 is completely wrapped in the dielectric portion 11b, in this case, if a large deviation occurs in a certain portion of the inner electrode layer 111 during the manufacturing process, the conductive portion 11a of the inner electrode 11 after cutting is deviated, and the conductive portion 11a is completely wrapped in the dielectric portion 11b, so that the deviation abnormality occurring in the inner electrode 11 cannot be identified in appearance, the deviation abnormality caused by the process cannot be effectively and quickly identified and corrected at the front end, and can only be detected by the destructive slicing/grinding sheet analysis, or the CT detection, the electrical performance test, and other delayed inspection modes, which have high detection cost and high risk of defective products.
Referring to fig. 4, in order to solve the above problems, the present invention provides an electronic component comprising an internal electrode 11, the internal electrode 11 being cut from a bar 1, the bar 1 comprising a plurality of internal electrode layers 111 laminated to each other, the internal electrode layers 111 comprising a membrane 11b1 and a plurality of electrode sheets 11a1 attached to the membrane 11b1, a plurality of conductive portions 11a being formed in the bar 1 by laminating a plurality of electrode sheets 11a1, cutting lines 21 being provided on an outer edge of the bar 1, the cutting lines 21 being generally marked 31 on an upper surface of the bar 1 and forming cutting line identification areas 20 around an outermost periphery of the bar 1; the inner electrode cutting area 10 to be cut is formed in the cutting line marking area 20, the inner electrode cutting area 10 is an area where a plurality of conductive parts 11a are located, wherein a plurality of electrode pieces 11a1 on the same film 11b1 are distributed in a matrix, the electrode pieces 11a1 on the electrode layers 111 in two adjacent layers are distributed in a staggered manner, and it is to be reminded that the staggered distribution means that, regarding one conductive part 11a, the projections of the electrode pieces 11a1 of the first, third, fifth, seventh and other odd layers are overlapped with each other, the projections of the electrode pieces 11a1 of the second, fourth, sixth and eighth and other even layers are overlapped with each other, and the electrode pieces 11a1 of the odd layers and the even layers are offset by a set distance along a certain direction, so as to form the staggered distribution of the electrode pieces 11a1 of the two adjacent layers. Thus, the inner electrode 11, which is obtained by cutting the bar 1, as part of the bar, likewise comprises a number of mutually laminated inner electrode layers 111, the inner electrode layer unit comprising a membrane 11b1 and a number of electrode plates 11a1 attached to the membrane.
On the above-mentioned bar block 1, a plurality of marks 31 are further attached to the membrane 11b1 on each of the inner electrode layers 111, the color of the marks 31 is different from that of the membrane 11b1, the marks 31 are distributed at the margin positions between the plurality of electrode plates 11a1, and the marks 31 intersect with the projection of the cutting line 21 in the lamination direction.
When the above-mentioned block 1 is cut, a plurality of marks 31 are provided on the film 11b1 of each inner electrode layer 111, and each mark 31 intersects with the projection of the cutting line 21 in the stacking direction of the block 1, so that a mark portion cut surface formed by the plurality of marks 31 always appears on the surface of the inner electrode 11 formed after cutting, that is, at least a part of the mark 31 is exposed on the outer surface of the inner electrode, and the offset state of the corresponding inner electrode layer 111 can be recognized by the appearance of the mark portion cut surface.
In this embodiment, as shown in fig. 4, in particular, a plurality of marks 31 are disposed on the membrane 11b1 on each inner electrode layer 111 on the bar 1, the plurality of marks 31 are distributed at the margin positions between the plurality of electrode pads 11a1 on each membrane 11b1, when the plurality of inner electrode layers 111 are laminated and pressed together, a plurality of layers of marks 31 form a mark portion 30 in the lamination direction (i.e. the direction perpendicular to the paper surface in fig. 4), the mark portion 30 is formed similar to the conductive portion 11a formed by the plurality of layers of electrode pads 11a1, and each layer of marks 31 intersects with the projection of the cutting line 21 in the lamination direction (i.e. the direction perpendicular to the paper surface in fig. 4), so that the cutting device must act on the mark portion 30 when cutting the bar 1, and the cut product surface forms a cutting surface formed when cutting the mark portion 30, for example, the bar 1 of fig. 4 is cut along the inner electrodes 11 formed by cutting along the cutting lines 21a, 21b, 21c, 21d, respectively, and when cutting, as shown in fig. 5, the cutting line 21a cuts the marking portions 30c, 30d, the cutting line 21b cuts the marking portions 30f, 30a, the cutting line 21c cuts the marking portions 30d, 30e, 30f, the cutting line 21d cuts the marking portions 30a, 30b, 30c, and the internal electrodes 11 formed after cutting have a structure schematic diagram, as shown in fig. 6, in which a plurality of marking portion cutting surfaces formed by cutting the marking portions 30a, 30b, 30c, 30d, 30e, 30f, for example, marking portion cutting surfaces 30a1, 30a2 formed by cutting the marking portion 30a, marking portion 30c1, and the overall judgment in appearance is made by these marking portion cutting surfaces, further, the offset state of the inner electrode layer 111 in the conductive portion 11a located inside can be recognized because the electrode sheet 11a1 on the inner electrode layer 111 is fixed in position relative to the mark 31, and therefore, when the inner electrode layer 111 is greatly offset, the mark 31 thereon is synchronously offset, and the offset state of the inner electrode layer 111 is exposed to the surface of the inner electrode 11 through the cut surface of the mark portion 30 formed by stacking the marks 31, thereby realizing the external recognition.
Specifically, referring to fig. 7, for example, when the whole of the inner electrode layer 111 in the inner electrode 11 is shifted rightward, the conductive portion 11a is shifted rightward as a whole, and at this time, the identification can be made by the external marker cut surfaces 30a1, 30c1, that is, at this time, the marker cut surfaces 30a1, 30c1 are shifted rightward simultaneously and take on a state of being wide in upper and narrow in lower.
In the product manufacturing process, the trial cutting of the bar block 1 can reflect the offset condition of the inner electrode layer 111 in the whole bar block 1, and can timely cut and adjust the bar block 1 with offset, thereby greatly improving the yield.
In some embodiments, the shape of the mark 31 may be one of a bar, a square, a rectangle, and a circle, and the shape of the mark 31 is preferably a square, for example, the square mark 31 has a length and a width of 0.1mm.
In some embodiments, the mark 31 is preferably made of a material having a different color from that of the dielectric portion 11b (i.e., the film 11b 1), and the cut surface of the mark formed on the appearance surface of the cut product has a different color from that of the dielectric portion 11b by providing the material having the different color, so that the cut surface of the mark is more prominent and is easy to identify. Preferably, the mark 31 is made of one of nickel (Ni) paste, silver paste, copper paste, and resin paste by drying.
In some embodiments, the mark 31 may be applied by screen printing, spraying, vacuum sputtering, vacuum coating, or photo-etching, or a combination of the above, preferably, the mark 31 is applied to the membrane 11b1 by screen printing, which has low cost, high efficiency and good stability, and can more meet the actual production requirement.
In some embodiments, the length/width dimension of the mark 31 is slightly smaller than the margin of the inner electrode 11 in the length/width direction, and accounts for 10-80% of the margin of the inner electrode 11, wherein the margin is the distance from the edge of the conductive portion 11a to the edge of the dielectric portion 11b in the inner electrode 11.
In some embodiments, it is preferred that the centerline of the mark 31 coincides with the projection of the cut line 21 in the stacking direction. The advantage of this arrangement is that in the normal state, the cutting device will cut through the center line of the marking part 30 when cutting along the cutting line 21, so as to equally cut the marking part 30, the marking part cutting surface formed by the cutting device is in an equally divided state, and when the internal electrode is offset, the marking part cutting surface generated after cutting is in an unequally divided state, so that the offset state is displayed more conveniently, and the recognition efficiency is further improved.

The mark 31 is preferably made of a material having a color different from that of the dielectric portion 11b, and the mark cut surface formed on the cut product appearance surface is made to have a color different from that of the dielectric portion 11b by the arrangement of the material having a different color, so that the mark cut surface is more prominent and easy to recognize. The mark 31 is preferably attached to the membrane 11b1 by screen printing, which has low cost, high efficiency and good stability, and can meet the actual production requirement.
