At this time, the guide pin 32a is formed in a state protruding from the window portion 33a to the upper side (Z1 side).

In addition, the manufacturing jig 30 includes the abutment 31, the convex block 32, and the punch plate 33 described above. In addition, there may be a case where the auxiliary material sheet 20 is stuck on the lower surface of the punch plate 33 or the intermediate product 10 described later is stuck on the upper surface of the punch plate 33. In this case, processing such as increasing (roughening) the surface roughness of at least one of the upper surface or the lower surface of the punch plate 33, or performing processing on at least one of the upper surface or the lower surface of the punch plate 33 may be performed. It is difficult to attach the materials of the auxiliary material sheet 20 and the intermediate product 10.

(4) The fourth step: the configuration of the intermediate product 10 (corresponding to the intermediate product arranging step) The intermediate product 10 is arranged on the upper side (Z1 side) of the punch 33 described above. FIG. 5 is a schematic diagram showing a state where the intermediate product 10 is disposed on the upper part of the punching plate 33 shown in FIG. 4. As shown in FIG. 5, the intermediate product 10 is arranged in a state of overlapping the punch 33. A guide hole 13 is provided in the intermediate product 10, and a guide pin 32 a inserted through the window portion 33 a is inserted into the guide hole 13. Thereby, the intermediate product 10 is positioned with respect to the auxiliary material 21. In addition, a guide pin (not shown) is provided on the base 31, and the guide pin is inserted into a hole (not shown) of the punch plate 33, whereby the base 31 and the punch plate 33 are positioned.

(5) Fifth step: cutting of the auxiliary material 21 from the frame-shaped waste portion 22 and adhesion of the auxiliary material 21 to the intermediate product 10 (corresponding to the cutting step and the fixing step) Next, the auxiliary material 21 is cut from the frame-shaped waste portion 22 After the material 21 is cut, the auxiliary material 21 is adhered to the intermediate product 10. FIG. 6 is a schematic diagram of a state in which the pressing member 60 is located at an upper portion of the intermediate product 10 shown in FIG. 5. When the auxiliary material 21 is cut from the frame-shaped waste portion 22, as shown in FIG. 6, the pressing member 60 is positioned on the upper side (Z1 side) of the intermediate product 10. The pressing member 60 is a member that configures a flexible printed circuit board manufacturing device 50 together with the manufacturing jig 30. The pressing member 60 may drive the pressing mechanism 80 that performs a pressing operation in accordance with an instruction from the control device 70 to perform the operation.

The pressing member 60 is a member that presses the punch 33 and the intermediate product 10 downward (Z2 side) together. Therefore, the bottom surface of the pressing member 60 is provided larger than the area of the window portion 33a, and the intermediate product 10 located at the upper portion of the window portion 33a is not moved relative to the punch plate 33 downward (Z2 side). That is, the pressing member 60 is provided to press at least a part of the punch plate 33 around the window portion 33a.

In addition, it is preferable that the pressing member 60 presses the punch plate 33 around the window portion 33a with the window portion 33a completely covered. The pressing member 60 is not limited to the case shown in FIG. 6. For example, the pressing member 60 may be made smaller in area than the window portion 33a, and may be pressed on a portion other than the window portion 33a of the punch 33. In addition, for example, a member having at least one longitudinal or transverse direction having a size smaller than the window portion 33a, such as a rod, may be used as a pressing member, and the hedge plate may be hung on the window portion 33a with the pressing member. 33 Press.

FIG. 7 is a schematic diagram of a state in which the pressing member 60 shown in FIG. 6 is moved downward (Z2 side) and the auxiliary material 21 is cut from the frame-shaped waste portion 22. When the pressing member 60 moves to the lower side (Z2 side), as shown in FIG. 7, the punch 33 presses the frame-shaped waste portion 22, and the frame-shaped waste portion 22 moves to the lower side (Z2 side). However, since the auxiliary material 21 is placed on the convex block 32, it does not move to the lower side (Z2 side). Thereby, the connection portion 23 is cut, and the auxiliary material 21 is cut and separated from the frame-shaped waste portion 22.

After the cutting and separating, when the pressing member 60 moves further downward (Z2 side), the auxiliary material 21 comes into contact with the intermediate product 10 in a pressed state. Through this pressed state, the auxiliary material 21 is fixed to the intermediate product 10. In addition, fixation can be achieved by using a fixing adhesive material or an adhesive material at a bonding portion of the intermediate product 10 and the auxiliary material 21 by a method such as thermocompression bonding. In addition, the "fixing" in the above-mentioned fixing step includes temporary fixing that is temporarily fixed, but full fixing that is not temporary temporary fixing is also included in "fixing" in the fixing step.

(6) The sixth step: re-arrangement of the auxiliary material 21 and the repetition of the third to fifth steps, as described above, after the fixing of the auxiliary material 21 at a certain position is completed, the auxiliary material sheet 20 is relative to the convex block 32 When moving, the auxiliary material 21 existing on the frame-shaped waste part 22 is placed on the convex block 32, and the guide pin 32 a is inserted into the guide hole 25 of the other auxiliary material 21. In the following description, this operation is referred to as "rearrangement of the auxiliary material 21".

Then, the operations from the third step to the fifth step are repeated. In addition, the relocation operation of the auxiliary material 21 and the repetition of the operations of the third step to the fifth step can be performed until the auxiliary material 21 no longer exists on the frame-shaped waste portion 22.

(7) Seventh step: subsequent steps after fixing After the fixing of all necessary auxiliary materials 21 with respect to the intermediate product 10 is performed, the subsequent steps are performed. As a subsequent step, for example, there is a step of completely adhering the auxiliary material 21 that is temporarily fixed to the intermediate product 10 through the adhesive material used in the fixing or the thermal curing of the adhesive material, etc., to the intermediate product 10. In addition, various components are pasted or processed through other processes as needed to form a flexible printed circuit board as a product.

<About effect> According to the manufacturing method of the flexible printed circuit board comprised as mentioned above, the flexible printed circuit board manufacturing jig 30, and the flexible printed circuit board manufacturing apparatus 50, the following effects are produced.

That is, in the auxiliary material arranging step, when the auxiliary material piece 20 holding the auxiliary material 21 on the frame-shaped scrap portion 22 is disposed on the manufacturing jig 30, the auxiliary material 21 is disposed on the cutting portion of the manufacturing jig 30. In addition, in the step of arranging the blanking member, a punching plate 33 (punching member) having a window portion 33a corresponding to the auxiliary material 21 and abutting the frame-shaped waste portion 22 is provided at the window portion 33a and the auxiliary material at the cutting portion. Configure in the 21-bit alignment state. In addition, in the intermediate product arranging step, the intermediate product 10 is aligned with and arranged on the punch plate 33 (punching member). Further, in the cutting step, the punching plate 33 (punching member) is pressed against the auxiliary material sheet 20, and the auxiliary material 21 is cut and separated from the frame-shaped scrap portion 22. In addition, in the fixing step, the auxiliary material 21 is fixed in a state of being aligned with respect to the intermediate product 10.

Therefore, the auxiliary material 21 can be arranged via the auxiliary material sheet 20. Therefore, for example, even when the size of the auxiliary material 21 is small and it is difficult to handle, the auxiliary material sheet 20 having a larger size can be disposed on the convex block 32, so that the processing of the auxiliary material 21 becomes easy. In addition, one auxiliary material sheet 20 can be used to attach a plurality of auxiliary materials 21 to the intermediate product 10 at the same time. Therefore, as compared with the case where the auxiliary materials are bonded one by one by the manual work of the operator as in the previous manufacturing steps, the man-hour can be reduced, and the production efficiency can be improved.

Further, in the present embodiment, a convex block 32 protruding from a base 31 having a planar shape on the upper surface 31 a is disposed on a cutting portion where the auxiliary material 21 is cut from the frame-shaped scrap portion 22. In addition, in the punching member arrangement step, the auxiliary material 21 is placed on the convex block 32. Therefore, the auxiliary material 21 as a cutting target is retained without being moved while being placed on the convex block 32, but the punching plate 33 (punching member) abutting the frame-shaped scrap portion 22 can be moved toward the base 31. Therefore, the auxiliary material 21 can be reliably cut from the frame-shaped scrap portion 22.

Furthermore, in this embodiment, in the cutting step, the pressing member 60 is positioned on the opposite side of the punch plate 33 (punching member) with the intermediate product 10 interposed therebetween. At the same time, the auxiliary member 21 is cut off from the frame-shaped scrap portion 22 by moving the pressing member 60 relative to the convex block 32.

Therefore, by moving the pressing member 60 downward (Z2 side), that is, the base 31 side, the frame-shaped scrap portion 22 can be moved downward (Z2 side), that is, the base 31 side, with respect to the auxiliary material 21, so that This makes it possible to cut the auxiliary material 21 from the frame-like waste portion 22. Therefore, the auxiliary material 21 can be easily cut from the frame-shaped scrap portion 22, and in particular, a plurality of auxiliary materials 21 can be cut simultaneously by one cutting operation. Thereby, man-hours can be further reduced, and production efficiency can be further improved.

In the present embodiment, a guide pin 32a is provided on the convex block 32 so as to protrude toward the window portion 33a. In addition, a guide hole 25 and a guide hole 13 into which the guide pin 32 a is inserted are formed in the auxiliary material 21 and the intermediate product 10, respectively. In the auxiliary material arranging step, the positioning of the auxiliary material 21 with respect to the convex block 32 is performed by inserting the guide pin 32 a into the guide hole 25 of the auxiliary material 21. In addition, in the intermediate product arranging step, the positioning of the intermediate product 10 with respect to the auxiliary material 21 is performed by inserting the guide pin 32 a into the guide hole 13 of the intermediate product 10.

Therefore, the auxiliary material 21 and the intermediate product 10 can be reliably aligned with the convex block 32. This can prevent misalignment when the auxiliary material 21 and the intermediate product 10 are bonded together.

In addition, in the present embodiment, when the auxiliary material 21 remains on the auxiliary material sheet 20 after the fixing step, the auxiliary material sheet 20 can be moved to perform the convex block in which the auxiliary material 21 is disposed on the manufacturing jig 30 again. Auxiliary material configuration steps on 32 (cutting parts). In addition, after the auxiliary material arranging step, the blanking component arranging step, the intermediate product arranging step, the cutting step, and the fixing step can be performed again.

By doing so, the operation of adhering the auxiliary material 21 to the intermediate product 10 multiple times can be performed using one auxiliary material sheet 20. Therefore, the processing of the auxiliary material 21 becomes easy at every sticking operation. In addition, since a plurality of auxiliary materials 21 can be attached to the intermediate product 10 at the same time during each sticking operation, man-hours can be reduced, and production efficiency can be improved.

Moreover, in this embodiment, the pressing member 60 is arrange | positioned on the opposite side (Z1 side) of the punching plate 33 (punching member) via the intermediate | middle product 10. The pressing member 60 moves the frame-shaped waste portion 22 relative to the auxiliary material 21 by applying a pressing force to move the intermediate product 10 and the punching plate 33 (punching member) to the base 31 side. Therefore, the auxiliary material 21 can be easily cut from the frame-shaped scrap portion 22, and in particular, a plurality of auxiliary materials 21 can be cut simultaneously by one cutting operation. Thereby, man-hours can be further reduced, and production efficiency can be further improved.

<Modifications> Although an embodiment of the present invention has been described above, the present invention can be modified in various ways. This will be described below.

In the above-mentioned embodiment, the convex block 32 corresponds to a cutting portion. However, the cutting portion is not limited to the convex block 32. For example, a movable operating member that can be moved upward from the upper surface 31 a of the base 31 may be provided on the manufacturing jig 30. In this case, the movable member can be formed into a structure that is initially on the same plane as the upper surface 31a of the base 31 or recessed from the upper surface 31a, but when the auxiliary material 21 is punched from the frame-shaped waste portion 22 The movable member protrudes from the upper surface 31a.

In the above-described embodiment, the punching plate 33 corresponds to a punching member. However, the punching member is not limited to the punch plate 33. For example, a member in which a cutting tool or the like is mounted on a plate-shaped or block-shaped member may be used as the punching member.
