However, when the cable portions having different thicknesses are perforated, the occurrence of the perforation deviation occurs when the die is touched by the time difference. In particular, the wire portion is required to be a material having good buckling characteristics. When the cable portion formed by the soft material first touches the tip of the die, it is easy to produce a filamentous burr due to the deviation of the perforation... When the tip of the die is: Sometimes it is easy to make a gap in the knife to shorten the life of the mold. In the ejection device described in Patent Document 3, the closed section is formed into a V-shape or a half-brieze _, but in the same way, when the cutting edge is linear, the filament-like burr cannot be infused, and the front end has When the acute angle is partially 1 77, the life of the metal mold is 1354515 • * · Short. Further, since the chip is only pressed by the blade edge, when the material which is still flexible is pierced, the chip may jump to the upper portion of the printed wiring board due to the rebound. Furthermore, although it is disclosed that the blade tip is formed into a waveform having a side view, in this case, the acute angle portion of the blade edge is increased, the mechanical strength is weakened, and the life is easily shortened at the blade edge to shorten the life. Thus, the present invention has an object of providing a die which can suppress the generation of punched burrs while ensuring the life of the punch in the punching process of the printed wiring board. [Means for Solving the Problems] [0018] The present invention has been made in order to achieve the above object, and the invention described in claim 1 provides a die which is used for punching of a printed wiring board, and is characterized in that As viewed from the circle, in the lower portion of the die, concave and convex portions having inclined sides or curved sides having the same shape are continuously formed, and from the bottom view, the concave and convex portions are diagonally parallel to the entire lower portion Settings. [0019] According to this configuration, since the uneven portion in the side view to the same shape is continuously formed in the lower portion of the die, when the die is lowered and the convex portion of the uneven portion hits the printed wiring board, the first printed wiring board is cut into Dotted. On the other hand, the cutting portion which is pressed by the blade edge and which is in the form of a broken line is continuously cut as being connected. Therefore, even if the direction of the cutting is to be shifted to the 'dashed line', the cut is cut, and the part of the cut is not broken. Moreover, because the embossing ==: is closed, it is possible to prevent the overall generation of the hair from being obliquely flat. It seems that the lower concave portion is in contact with all the side edges '[〇〇2()] 纟4. And the above effect occurs. The invention system described in the second paragraph of the patent is provided as a patent application. According to this configuration, since the concave-convex portion has a corrugated shape, the cutting system based on the cutting edge of the cutting edge is smoothly performed by the cutting of the cutting direction. Also good. [Effect of the Invention] [0022] The present invention is formed by continuously forming a concave-convex portion having the same shape in a side view, for example, a corrugated shape in a lower portion of the die, and cutting the printed wiring board into a broken line to make a broken line. The part can be continuously cut like a joint, so by absorbing the offset of the cutting direction, the generation of the burr can be prevented. In addition, because the concave and convex portions of the waveform shape are arranged diagonally in parallel across the lower part of the die, the perforation line is in that direction to prevent the generation of burrs. "Furthermore, the mechanical strength is ensured and the metal mold can be maintained. Longer life. Further, since the chips are pushed out by the entire lower portion of the die, the chips are surely dropped into the opening of the mold, and the discharge property of the chips is also improved. [Embodiment] [Best Embodiment of the Invention] [0023] For the die according to the present invention, a suitable embodiment will be described. In order to achieve the purpose of providing a die that ensures the life of the die while suppressing the occurrence of the punching burr in the punching process of the printed wiring board, the present invention is achieved in the following manner, that is, to provide a printed wiring board. The punching die is formed in a lower side 4 of the die, and the side view is a concave s portion having an inclined side or a curved side having the same shape, and the concave and convex portion is spread over the lower portion from the bottom view circle. Fully diagonally parallel. [Embodiment 1] [0024] Fig. 1 is a front view circle of a die, Fig. 2 is a circle of the α-α arrow direction of Fig. 1, and Fig. 3 is a view of the arrow direction of Fig. 1. Further, the flexible printed wiring board 50 and the product outline 51 of each of the perforated flexible printed wiring boards 5 are completely the same as those shown in Figs. 9 to 11, and the overlapping description will be omitted. [0025] As shown in Fig. 1 to Fig. 3, a die η is placed above the mold 1〇, and the die 11 is lowered to pierce the perforated portion 60 of the flexible printed wiring board 5 〇 a shown in Fig. 11. In the lower portion of the die 11, the side view X is formed such that the inclined portion or the curved portion 12b of the same shape is continuously formed. In the embodiment of the present invention, the aforementioned concave-convex portion 12 is formed into a corrugated shape having the same shape, and the uneven portion 12 is obliquely parallel to the entire lower portion of the die as viewed from the bottom view. Settings. [0026] As described in the circle 3, the uneven portion is indicated by a broken line. In the concave portion 12a, when the convex portion 12b is indicated by a solid line, each side η "the direction of the γ direction (up-and-down direction) Hb in the direction of the die (the horizontal direction in Fig. 3) is used, and the concave portion 12a and the concave portion 12a are The convex portions (10) are formed in parallel at a substantially oblique angle. [0272] Thus, the direction in which the concave and convex portions 12 are formed is formed to be obliquely parallel from the bottom view, so that which is in the χ direction or the γ direction The side faces 11a and Ub and the end surface shape of the uneven portion 12 (the waveform shape in the present embodiment) can be uniformly displayed. The inclination angle of the uneven portion 12 to each of the sides ua and ilb may not necessarily be 45. It is an angle of inclination of 40° or 35 degrees with respect to one side. [0028] FIG. 4 is a view showing a state in which the flexible printed wiring board 5 is placed on the mold 1 , and has a shield layer 54 on the upper and lower sides. The part encapsulating portion 55 of the 54 and the component encapsulating portion 56 having no shielding layer on the upper and lower sides are connected to the cable 57. The outer portion of the perforated portions is the discarding portion 6^. [0029] FIG. 5 is a view showing the outline 51 of the article. Top view of the perforation project, Figure 6 shows the cut When the die 1 is lowered by 1354515, as described by the circle 5 (a), the convex portion I2b of the uneven portion 12 formed at the lower portion of the punch 1 is first abutted to the thickest portion. In the component encapsulating portion 55 having the concealing layer, the cutting predetermined line L of the component encapsulating portion 55 is pressed against the convex portion 12b, and a portion L1 of the cutting predetermined line L is cut into a broken line as described in the circle 6 (a) [0030]

[0031] As shown in FIG. 5(b), when the cutting line of the part material portion 55 is tied and the cutting is finished, 'one part of the cable portion 57 is cut and cut into a line shape', and at the same time, there is no shielding. The component encapsulation portion of the layer starts cutting the cutting of the 4-wire portion 57 and the part encapsulation portion 56 ° as the « of the component encapsulation portion 55, such as the loop 6U. - the 'dashed-shaped portion B is connected to the cut portion L2 Was torn and continued to be cut. As shown in Fig. 5(c), when the cable portion side is cut, the cutting is terminated by the dotted line-shaped cutting from the component encapsulating portion 5 and the second mounting portion 55. In the case of the cutting of the straight line portion 13 or the like, the direction of the cutting L1 is shifted, as shown in Fig. 2(d), the broken line L1 is cut as shown in Fig. 2(d). The portion where the mechanical strength of the material is weak is sought, and the uncut portion L2 between the broken portions of the broken line is cut like a tear, so that the deviation of the direction in which the cutting is performed is absorbed to prevent the occurrence of burrs. [0034] FIG. 7 shows the dimension "the experimental result of the cutting according to the cutting result", the depth of the uneven portion 12, and when the depth is less than 〇3 mm, the broken portion of the cable portion 57 cannot be cut. It is easy to produce burrs. On the other hand, when the depth is higher than 〇. 8 mm, since the height of the tip of the die 11 is increased, the life of the die 11 becomes short. Therefore, the depth of the uneven portion 12 is preferably 0.3 to 〇 8 mm. [0035] Further, when the pitch of the uneven portion 12 is less than 1. 〇 mm, the tip end shape of the convex portion 12b is made sharper at the depth of 0.3 mm, so that the life of the die is difficult to ensure. On the other hand, when the pitch is larger than 2.0 mm, when the broken line of the cable portion 57 is cut by both sides, an offset occurs in the breaking direction to cause a burr. Therefore, the pitch of the concavo-convex portions 12 is preferably 1 · 〇 〜 2. [0036] Fig. 8 shows a modification of the shape of the uneven portion ,2, and Fig. 8(a) is provided with a mountain-shaped uneven portion 13, and Fig. 8(b) is provided with a corrugated shape (inverted semicircular shape). The shape 14 can be obtained in the same manner as the uneven portion 1 2 of the waveform shape. [0037] Further, the present invention can carry out various changes of 1354515 without departing from the spirit of the present invention, and the present invention can of course be applied to the changer β (simple description of the figure) [0038] [Fig. 1] The die involved in the invention has a front circle.
