[0002] Some common circuit elements, such as ceramic substrates, need to be coated, welded, etched and diced to obtain the required finished product during production. The industry often uses manual operation for dicing, and a dicing jig is needed in the existing manual dicing.

[0003] However, the inevitable problem of manual dicing is fatigue, and the structure of the dicing jig itself is closely related to fatigue. A dicing jig that is easy to hold and saves labor can delay the occurrence of fatigue to a certain extent. Therefore, we propose a dicing jig that is easy to hold. SUMMARY

[0006] As a preferred, the inner side of the dicing groove is provided with an elastic limiting piece, which is compressed when the dicing sample is inserted, so that the depth of the dicing groove is reduced, and when the elastic limiting piece cannot be compressed further, the depth of the dicing groove is reduced to the length of the dicing sample.

[0007] As a preferred, the elastic limiting piece comprises a limiting plate and a spring, and the spring is compressed to its elastic limit when the depth of the dicing groove is reduced by a set length; different dicing grooves can be provided with springs with the same or different elastic limits.

[0008] As another preferred, the elastic limiting piece comprises a limiting plate and a spring, the limiting plate comprises an extension part towards the inner side of the dicing groove, one end of the spring is located in the extension part, the extension part and the innermost side of the dicing groove abut when the depth of the dicing groove is reduced by a set length, the difference between the depth of the dicing groove and the length of the extension part is the length of the dicing sample, and the multiple extension parts provided by multiple dicing grooves have the same or different lengths.

[0009] As a further preferred embodiment, the elastic limiting member further includes a telescopic rod, and the extension portion is provided with multiple extensions at intervals. The two ends of the telescopic rod are respectively disposed between the limiting plate and the split groove, and one or more telescopic rods are provided.

[0010] As a preferred embodiment, the main body of the shard is a one-piece rectangular parallelepiped shape, and the four sides of the main body of the shard are provided with shard grooves at the same height. The four shard grooves are of the same depth and are connected in sequence to form a rectangular annular groove structure.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] The user holds the shortest side of the split disc, with the gripping surface close to the palm. Because the gripping surface is short, it is easy to hold, making it more stable and comfortable to use. Since the shortest side is used for gripping, the corresponding longer side is used for splitting the disc. Therefore, the hand position is farther from the disc, which requires less effort when splitting the disc according to the lever principle. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] Example:

[0031] Reference Figures 1 to 7 As shown, this embodiment proposes a tooling for cleaving wafers, including a wafer body 1 and a wafer groove 2. The wafer groove 2 is formed on the wafer body 1, and one or more wafer grooves 2 are provided. A gripping surface is formed on the opposite side of the wafer body 1 where the wafer groove 2 is located, and the height of the gripping surface is the length of the shortest side of the wafer body 1. When using this cleaving tooling, the wafer groove 2 corresponds to the wafer sample 3. Obviously, when holding it, one holds the opposite side of the wafer groove 2. The shape of the cleaving tooling is generally a cuboid. Therefore, when the height of the corresponding gripping surface corresponds to the length of the shortest side of the wafer body 1, it means that the user holds the shortest side of the wafer body 1. If the height of the gripping surface is large, the gripping surface will be close to the palm when holding it, and it will be difficult for the fingers to grasp the two adjacent sides of the gripping surface. Therefore, this cleaving tooling sets the wafer groove 2 on a specific surface of the cleaving tooling, so that the opposite side is easy to grip, thus making it more stable and comfortable to use. It is also foreseeable that the shortest face is used for gripping, while the corresponding longer face is used for splitting. Therefore, the hand gripping point is far from the splitting point, and the force required for splitting is relatively reduced according to the lever principle.

[0032] In such Figure 1 In the shown fragment body 1, the shortest side is obviously the side corresponding to its height, so the gripping surface corresponds to the four sides. For example, the face containing the fragment groove 2 is the front side, and the opposite face is the back side. Therefore, the gripping surface is the back side. Since the back side is shorter, gripping is simpler. If the bottom surface is set as the gripping surface, the fragment groove 2 is at the top. When gripping the bottom, the height corresponding to the bottom is obviously much greater than that of the front side. In this case, the gripping surface occupies a larger area of ​​the palm, making it difficult for the fingers to grip the fragment fixture tightly, thus making it inconvenient to hold.

[0033] Example 2:

[0034] Based on Example 1, since the thickness of the sharding groove 2 and the thickness of the sharded sample 3 are similar, smaller products or scraps generated after sharding are easily retained in the sharding groove 2. To prevent them from getting stuck and occupying the sharding groove 2, refer to... Figure 2 , Figure 3In this embodiment, an elastic limiting member is provided on the inner side of the cleavage groove 2. When the cleavage sample 3 is inserted, the elastic limiting member is compressed to reduce the depth of the cleavage groove 2. When the elastic limiting member can no longer be compressed, the depth of the cleavage groove 2 shrinks to be consistent with the cleavage length of the cleavage sample 3. In this embodiment, the elastic limiting member is compressed to a state where it cannot be compressed further during use, so the depth of the cleavage groove 2 can be set. Therefore, in actual use, there will be no problem of poor cleavage effect due to the initial inconsistency between the depth of the cleavage groove 2 and the cleavage length of the cleavage sample 3. In order to ensure that the use process is relatively convenient, the elasticity of the elastic limiting member does not need to be too large. Otherwise, a large force needs to be applied during use to compress the elastic limiting member with the cleavage sample 3.

[0035] It is worth noting that the above-mentioned "elastic limiter cannot be compressed further" does not necessarily mean that the elastic limiter has been compressed to its elastic limit. The following two optional embodiments are presented for specific explanation.

[0036] (1) The elastic limiting component includes a limiting plate 7 and a spring 5. When the depth of the split groove 2 decreases by a set length, the spring 5 is compressed to its elastic limit. Different split grooves 2 can be equipped with springs 5 ​​with the same or different elastic limits. This embodiment corresponds to the situation where the spring 5 is compressed to its elastic limit, which is of course feasible.

[0037] (2)Reference Figure 2 , Figure 3 The elastic limiting member includes a limiting plate 7 and a spring 5. The limiting plate 7 includes an extension 4 facing the inside of the cleavage groove 2. One end of the spring 5 is located inside the extension 4. When the depth of the cleavage groove 2 decreases by a set length, the extension 4 abuts against the innermost side of the cleavage groove 2. The difference between the depth of the cleavage groove 2 and the length of the extension 4 is the cleavage length of the cleavage sample 3. Multiple extensions 4 provided for multiple cleavage grooves 2 have the same or different lengths. This embodiment corresponds to an example where the elastic limiting member is not compressed to its elastic limit. In this embodiment, the spring 5 only serves to provide restoring elasticity. The actual depth control is achieved by the abutting between the extension 4 and the innermost side of the cleavage groove 2. Therefore, by setting the length of the extension 4, the actual depth of the cleavage groove 2 can be easily controlled. In practical applications, we can set extensions 4 of different lengths on the same cleavage body 1, thereby obtaining cleavage grooves 2 of different depths on one cleavage body 1. Alternatively, an extension part 4 of the same length can be set so that the same fragment body 1 has the same fragment groove 2 depth, so that it can be used without distinguishing between the front and back.

[0038] When connected solely by spring 5, if the cleaved sample 3 is inserted into the cleaving groove 2 at an angle, one end of the sample 3 might act on the limiting plate 7 first, causing the limiting plate 7 to also tilt. Without manual correction, this could lead to defective products after cleaving. To avoid this problem, the elastic limiting component also includes telescopic rods 6. Multiple telescopic rods 6 are spaced apart on the extension 4, with both ends positioned between the limiting plate 7 and the cleaving groove 2. One or more telescopic rods 6 are provided. The telescopic rods 6 effectively prevent the limiting plate 7 from tilting. Once the telescopic rods 6 and the limiting plate 7 are fixed, the limiting plate 7 cannot tilt. Increasing the number of telescopic rods 6 can also increase the stability of the limiting plate 7 to a certain extent.

[0039] like Figure 1 As shown, the main body 1 of the split piece is a rectangular prism shape formed in one piece. The four sides of the main body 1 of the split piece are provided with split piece grooves 2 at the same height. The four split piece grooves 2 have the same depth and are connected in sequence to form a rectangular ring-shaped groove structure.

[0040] It is worth mentioning that in this application, the "height of the cleavage groove" refers to the distance between the upper and lower surfaces of the cleavage groove, which corresponds to the thickness of the cleavage sample 3; while the "depth of the cleavage groove" refers to the distance between the outer wall surface of the cleavage groove body 1 and the innermost wall surface of the cleavage groove 2, which corresponds to the length of the cleavage sample 3 each time it is cleaved.

[0041] Obviously as Figure 1 The cleavage body 1 shown can be formed by fixing two separate blocks through a central fixing hole. The split configuration offers greater flexibility. For example, one block has a cleavage groove 2 with a height of 1 mm and the other block has a cleavage groove 2 with a height of 2 mm. When the two are installed, they form a cleavage groove 2 with a height of 3 mm, which is suitable for cleaving samples with a thickness of 2 to 3 mm. Similarly, more blocks of different specifications can be set so that the depth of the cleavage groove 2 formed after installation can be easily adjusted as needed.

[0042] As shown in the figure, there are four elastic limiting components. The length of the limiting plate 7 is obviously smaller than the width of the corresponding shard groove 2. In fact, the limiting plate 7 does not need to be the same length as the shard groove 2. It can be used normally as long as there are at least two places where it abuts against the shard sample 3. The limiting plate 7 is a plate body. After the shard sample 3 is inserted, it fits and abuts against the limiting plate 7. As long as the length of the limiting plate 7 is not too short, it can be used. Of course, under the premise that different limiting plates 7 in adjacent shard grooves 2 will not interfere with each other, the longer the limiting plate 7 is, the better.

[0043] Of course, the cleavage body 1 can be set as a one-piece molded cuboid shape, and each of the four sides of the cleavage body 1 is provided with a cleavage groove 2, and the four cleavage grooves 2 have at least two different groove heights. The one-piece molded cleavage body 1 can be directly set with cleavage grooves 2 of different heights, or it can be set with the same groove height, which can be applied to cleavage samples 3 of different heights.

[0044] Example 3:

[0045] Reference Figure 4 As shown, the main body 1 of the shard is a one-piece rectangular parallelepiped shape. Two shard grooves 2 are provided, located on opposite sides of the main body 1, and staggered in the height direction. This staggered height means they do not overlap at any height, and the shard grooves 2 are located on opposite sides. Figure 4 As shown, the depth of the cleavage groove can be increased.

[0046] like Figures 5 to 7 As shown, the main body 1 of the shard also has shard grooves 2 on two other sides. These two shard grooves 2 are staggered in the height direction, and their heights are also staggered from those of the two shard grooves 2 on the other two sides. Since all four shard grooves 2 are staggered, all four shard grooves can be set to a large depth. However, the number of shard grooves 2 affects the groove height that can be set, so it can be selected as appropriate.

[0047] In some embodiments, the fragment body includes two separate blocks, each block having a fixing hole in the middle for fixing; a groove is provided on one side of the contact surface of the two blocks, and when they are in contact, the two grooves of the two blocks combine to form the fragment groove.
