Description

  In the present invention, a plurality of sheet-like laminating materials, each having a corresponding imposition portion arranged at a predetermined position, are laminated, and a laminated product of a unit is arranged in a multifaceted manner. The present invention relates to a stacking apparatus and a stacking method for manufacturing a stacked substrate product having a stacked structure.

Conventionally, as a method of manufacturing a multilayer product of a unit composed of a plurality of layers such as a multilayer printed wiring board, a plurality of layers are laminated to form a plurality of layers as shown in FIG. 5A. A manufacturing method is adopted in which a laminated substrate product 520 having a sheet-like laminated structure in which unit laminated products 530 are multifaceted is manufactured, and thereafter, each unit laminated product 530 is separated to obtain an individualized product. There is.
In this case, in the laminated substrate product 520 having a sheet-like laminated structure, the corresponding layer portions of the unit laminated product 530 are integrally connected to each other.
In the production of the laminated substrate product 520 having such a sheet-like laminated structure, for example, as shown in FIG. 5B, one of the plurality of imposition portions 511 of each lamination material forming each layer is provided. If there is a fatal defect that cannot be corrected in the imposition part of the part, that is, if there is a defective imposition part, the entire laminating material may be discarded despite the imposition part having no defect.
In addition, when the product itself becomes defective when it becomes a laminated product of a unit due to the defect of the material for lamination, this defect is called a fatal defect.
Further, in FIG. 5, x marks indicate defective imposition portions.
If it does in this way, it will become wasteful, so that the number of defect imposition parts is small, and it becomes the cause which the manufacture yield falls, so that the number of imposition parts of the lamination | stacking material increases.
On the other hand, as shown in FIG. 5C, when the laminating material 510 has few imperfections with a fatal defect, the laminating material 510 is used as it is and the yield of the type of laminating material 510 is increased as compared with the above case. Is also possible.
In this method, all the layers of the laminating material 510 are laminated to form a laminated substrate product 520, and the laminated product 530 in the unit of the imposition portion equivalent to the improper imposition portion of the laminating material is added to each unit. After being separated into the laminated product 530, the laminated product 530B in units of defective products was discarded.
However, in this method, when laminating one type of laminating material to the other type of laminating material, even if there is no fatal defect in the imposition portion at a predetermined position of the one type of laminating material, When there is a fatal defect in the imposition portion corresponding to the predetermined position of the other type of laminating material, it corresponds to the predetermined position when a laminated substrate product having a sheet-like laminated structure is formed after lamination. The laminated product in the unit of the imposition part becomes a defective product.
In the case of this method, even if the yield for each type of laminating material is increased, the yield of the unit laminated product in the case of a laminated substrate product having a sheet-like laminated structure is lowered. It was a problem that caused a decline in work efficiency and waste of materials.

The laminating apparatus 100 of this example is configured by laminating a plurality of sheet-like laminating materials (corresponding to 510 in FIG. 5) arranged with an imposition portion facing a predetermined position. It is a laminating apparatus for producing a laminated substrate product (corresponding to 520 in FIG. 5) having a laminated structure in which laminated products (corresponding to 530 in FIG. 5) composed of wiring boards are arranged in many faces.
Then, for each type of lamination material, the position information of the imposition portion that is defective is recorded as the surface loss information of the lamination material in correspondence with each lamination material, and the lamination of each lamination material The data management unit 50 that records the position information of the imposition portion that is a defect of the object as the surface loss information of the laminate, and for each of the lamination materials, for each imposition material, for each imposition portion In addition, a predetermined inspection measurement is performed, pass / fail judgment of each imposition part is performed, the position of the defective imposition part is grasped, and information on the position of the defective imposition part is associated with each of the laminating materials to reduce the surface loss. As the information 51, the inspection / measurement processing unit 20 recorded in the data management unit and the surface loss information are acquired from the data management unit, and the stacking material is selected and stacked based on the acquired surface loss information. The laminating process for recording the surface loss information 52 of the laminated product A unit (30), in which are provided.

The stacking processing unit 30 in this example can wait for each stacking material of the same type corresponding to the surface loss information 51 for each stacking material, and selectively take out a desired stacking material. It is provided with a buffer unit 32 having a plurality of buffers (1 to n), and each lamination material is supplied from the manufacturing unit 10 that manufactures it to the inspection and measurement processing unit 20, and once for each lamination material of the same type Then, a predetermined buffer of the buffer unit 32 is made to wait.
In addition, as a buffer (1-n), although the thing of a magazine rug form is used normally, it is not limited to this.
And when laminating, it acquires the surface loss information 51 of the material for lamination from the data management unit 50, and based on the acquired surface loss information 51 and the surface loss information 52 of the laminate of the intermediate product, The laminating material to be laminated is selected and taken out from the buffer, and the laminating material is supplied to the laminating unit 31 where the laminating process is performed.
The stacking unit 31 stacks the layers of the layers at a time to stack the layered substrate products, sequentially stacks the layers of the layers of stacking materials to form the layered substrate products, A laminate of intermediate products obtained by laminating laminate materials can be prepared, and a laminate material can be further laminated thereon to form a laminate substrate product.
The laminated substrate product laminated by the lamination processing unit 30 is delivered to the final inspection unit 40.
In the stacking apparatus 100 of this example, when stacking, the stacking processing unit 30 acquires the surface loss information 51 and 52 from the data management unit 50, and the same positions of the surface loss positions are the same. In the order of increasing number of surface loss, priority is given to the lamination.

In the laminating apparatus 100 of this example, the buffer section of the buffer unit 32 of various laminating materials can keep the same type of laminating materials in one buffer, but the processing flow shown in FIG. As described above, it is possible to divide into two buffers corresponding to the surface loss information 51 of the laminating material and wait for them.
The processing flow shown in FIG. 3A will be briefly described.
The process of the inspection / measurement processing unit 20 performs inspection / measurement processes such as disconnection and short-circuiting when the stacking material (S11) is supplied from the manufacturing unit 10. (S12)
Then, the surface loss information of the laminating material, which is the position information of the imposition portion having a fatal defect, is obtained, and if there is an imposition portion of the surface loss, it is stored in a buffer of useful surface damage (S13 to S14), When there is no surface loss, it is stored in a buffer for no surface loss (S13 to S15), and is put on standby for stacking.
On the other hand, the surface loss information obtained as a result of the inspection measurement process (S12) is recorded in the data management unit 50 in correspondence with each lamination material.
The recorded information is supplied to the lamination processing unit 30 and used.

The recorded information is supplied to the lamination processing unit 30 and used.

The layered substrate product that has undergone the layering process is subjected to continuity inspection and the like by the final inspection unit 40. When the final inspection unit 40 inspects, the layered substrate product is preliminarily classified and waited based on the surface loss information. It is preferable from the viewpoint of inspection efficiency that a buffer unit (not shown) is provided. In this case, for example, the processing flow shown in FIG.
A lamination process is performed (S21), and a laminated substrate product is laminated (S22). On the other hand, the surface loss information 52 of each laminated substrate product, which is the final laminate, corresponds to each laminated substrate product. , Recorded in the data management unit 50. For each laminated substrate product, if there is a surface loss based on the surface loss information 52, it is stored in the buffer for the surface loss (S23 to S24), If there is no damage, it is stored in a buffer for no surface damage (S23 to S25) and waits for the final inspection (conductivity inspection or the like) in the final inspection section 40.
The recorded information is used for final inspection (continuity inspection, etc.) in the final inspection section 30. At the time of inspection, each laminated base material product is inspected on the entire surface if there is no surface damage. For those having the problem, the inspection efficiency can be improved by omitting the inspection of the imposition portion for surface damage.
Here, the buffer is allocated before the final inspection, but the inspection of the imposition may be omitted if there is a surface loss based on the surface loss information of each laminated base material product without distribution.

The operation of the lamination processing unit 30 will be further described.
In order to simplify the explanation, a case where two kinds of laminating materials of the first layer and the second layer are laminated will be described.
First, based on FIG. 2, it demonstrates, referring FIG.
For each of the two types of laminating materials of the first layer and the second layer, each laminating material is input from the manufacturing unit 10 to the inspection / measurement unit 20 to perform inspection / measurement processing, and an imposition portion for surface loss Is obtained in correspondence with each laminating material and recorded in the data management unit 50, and each laminating material 210 a as the first layer is stored in the first buffer 231. Each of the laminating materials 210 b as the second layer is stored in the second buffer 232.
Correspondence between each laminating material and its surface loss information 51 may be affixed with, for example, a sticker with a readable ID attached to each laminating material (210a, 210b).
The surface loss information is recorded in the data management unit 50 in correspondence with each lamination material of each buffer.
When stacking, the stacking processing unit 30 acquires the surface loss information 51 of each layer to be stacked from the data management unit 50, and for each layer, the number of surface losses at which the surface loss position is the same position. For example, if any of the laminating materials has a surface loss imposition portion of 1 or less, there is only one surface loss imposition portion at the same position. Each other (210A, 210B) is laminated.
When two sheets (210A, 210B) having only one surface-impositioned portion are laminated at the same position, the laminate 220 also has one surface-imposed surface-imposed portion. In the case of stacking those having only one imposition portion, there are two imposition portions with surface loss for the laminate.

In addition, for example, when any of the laminating materials has two or less surface imposition portions, the layers having only two surface loss imposition portions at the same position are preferentially laminated, The materials for laminating are also preferentially laminated with those having only one imposition portion having a surface loss at the same position.
This is the case, for example, when a laminating material having a surface damage imposition portion of 2 or more is discarded.
This will be described with reference to FIG. 1 based on FIG.
First, in the same manner as described above, for each of the two types of laminating materials of the first layer and the second layer, each laminating material is input from the manufacturing unit 10 to the inspection and measurement unit 20 to perform inspection and measurement processing. The surface loss information 51, which is the position information of the imposition portion of the surface loss, is obtained and recorded in the data management unit 50 in correspondence with each layering material, and each layering material that is the first layer a1 to an are stored in the buffer for the first layer, and the respective laminating materials b1 to bn which are the second layer are stored in the buffer for the second layer. (S31)
Next, the stacking processing unit 30 searches the stacking materials waiting in different buffers to determine whether there is a combination of the stacking materials ai and bj having the same position of the surface loss at two locations (S32).
When there is a combination ai, bj, the laminating materials ai, bj are supplied from the respective buffers (S33, S34) and laminated. (S35)
The laminating materials ai and bj are supplied, and the laminating materials are newly supplied as ai and bj to the positions where the respective buffers are vacant. (S36)
In addition, when there is no combination of the laminating materials ai and bj having the same position of the two-point surface loss, the stacking processing unit 30 has the same position of the one-side surface loss for the stacking materials that are kept waiting in different buffers. It is searched whether there is a combination of a certain material for lamination ai, bj. (S37)
If there is a combination ai, bj, the laminating materials ai, bj are supplied from each buffer (S38, S39) and laminated. (S35)
Here again, the laminating materials ai and bj are supplied and the laminating materials are newly supplied as ai and bj to the positions where the respective buffers are vacant. (S36)
When there is no combination ai, bj, the laminating materials a1, b1 are supplied from each buffer (S38, S40) and laminated. (S35)
By repeating the above series of processing steps (S32 to S40), the stacking process is continued.
In addition, when there are three or more surface loss imposition portions, any of the laminating materials is preferentially laminated in the descending order of the number of surface loss at the same position.
In this way, by preferentially laminating those with the same surface loss position, when it becomes a laminated base material product, the yield can be increased compared to the case where it is not, resulting in work efficiency. It will also improve the savings of materials.

The above example is an example, and the present invention is not limited thereto.
For example, a stacking unit may be provided for each step of sequentially stacking each layer, and the surface loss information of the stacking material or stack to be stacked for each step may be managed.
In this way, the flow work can be easily performed.

It is a block diagram which shows schematic structure of one example of embodiment of the lamination apparatus of this invention. It is a figure for demonstrating the relationship between processes, such as a lamination process, and the surface loss information of a data management part. FIG. 3A is a process flow diagram for explaining the buffer division of the laminating material, and FIG. 3B is a flow diagram for explaining the buffer division of the laminated substrate product after the lamination process. It is the flowchart which showed one example which supplies the lamination | stacking material from each buffer which waits for each lamination | stacking material of a 1st layer and a 2nd layer.
