[Prior Art] With the rapid development of the electronics industry, the fabrication technology of circuit boards, which are the basic components of electronic products, is becoming more and more important. The circuit board is generally made of a series of processes in which the copper-clad substrate is fabricated by the inner layer circuit, such as one-way, air, (four) (striping), black shadow, electroplating, outer layer number, and surface treatment. For details, see "DieleCtriC CharaCteriZaticm of Pri vs. ed dr- cuit board substrates" by C. H. Steer et al., Pr. ceedings 〇f the IEEE' Vol. 39, ν〇· 2 (August 2002). Among them, 'the flexible circuit board will be pre-set in the surrounding area when it is made'. The marginal area can prevent the overflowing knee from flowing to the last molded flexible circuit board during the pressing process, or prevent the overflow (four) to The press-fit device j contaminates the carrier of the press-fit device. Before the wetting process, the waste is caused by the overflow of the molten metal on the margin area or the plating of the excess copper layer. The cutting edge (striping) process usually takes the remaining area around the flexible circuit board. resection. When the remaining area of the flexible circuit board is cut, the general-purpose tool is used, and the four-parts are provided with four blades that match the fixed-size flexible circuit board. However, since the blade of the first boring die is fixed, a blade && die can only cut a flexible circuit board of the corresponding size. When the size of the flexible board changes in one direction, another die needs to be replaced for cutting. Thus, not 099112811 Form number Α0101 Page 4/18 page 0992022671-0 201136725 Only increase the cost of the die, and need to change the die repeatedly, resulting in wasted time and manpower' increased soft board manufacturing costs. [0004] [0005] [0007] 099112811 In view of this, in view of the above problems, it is necessary to provide a die that can effectively reduce the cost of the die and eliminate the need for repeated replacement, thereby reducing the manufacturing cost of the flexible circuit board. . SUMMARY OF THE INVENTION A die cutter will be described below in a specific embodiment. A die includes a base, a first blade, two second blades, a third blade, two fixing portions, and a positioning screw. The first blade and the two second blades are both fixed on the base. The two second blades are vertically connected to opposite ends of the first blade respectively. The third blade is parallel to the first blade. Each of the second blades is provided with a guide groove from a distal end of the first blade to a first blade. The two EI portions are respectively disposed at opposite ends of the third blade. Each of the fixing portions includes a guide bar and a positioning jaw. The guide rod slidably engages the guide groove. The positioning rods are perpendicular to the two ends of the guiding rods and the positioning rods are respectively located at two sides of the guiding rods and respectively have a threaded hole. The set screw is screwed into the threaded hole to press against the second blade so that the third blade and the second blade are relatively fixed. Compared with the prior art, in the die of the technical solution, since the fixing portion is fixed to the opposite ends of the third blade, the third blade can slide along the guiding groove of the second blade by the guiding rod of the fixing portion. In order to change the distance between the third blade and the first blade, the third blade and the second blade can be pressed against the second blade by the positioning screw and the threaded hole of the positioning rod of the fixing portion. The blade is relatively fixed, so that when the size of the flexible circuit board changes in a certain direction, the form number of the third blade pair can be adjusted by adjusting the shape of the die. 1010101 Page 5 / 18 pages 201136725 [0008] [0012] [0012] The flexible circuit board performs the cutting and removal of the margin area of the periphery of her circuit board.

Specifically, the positioning screw _ abuts « to the second outer side 304 of the second blade 3〇, so that the third blade 40 can be provided with the threaded hole 5〇2 of the positioning rod 54 at both ends and the set screw The screw of 60 is relatively fixed to the base 1〇. When the size of the flexible circuit board in the direction is changed, only the third blade 40' needs to be adjusted so that the "gauge" of the third blade 4G is moved toward or away from the first blade 2Q. The third blade 40 can be adjusted to a proper position, so that the area of the first blade, the two second blades 3, and the third blade 40 is corresponding to the size of the flexible circuit board, so that the first blade can be cut and removed. The flexible circuit board product is obtained by default in the margin area around the soft board. Moreover, the scale 36 on the second outer side 304 of the second blade 3 can be aligned with the third according to the size of the flexible circuit board. The blade 40 allows the third blade 40 to be accurately and quickly moved to the scale corresponding to the scale 36 and fixed. Compared with the prior art, in the die of the present technical solution, the opposite ends of the third blade are fixed. a fixing portion is provided, and the third blade can be slid along the guiding groove of the second blade by the guiding rod of the fixing portion to change the distance between the third blade and the first blade; and then, by positioning the screw with The threaded hole of the positioning rod of the fixing portion is screwed and pressed against the second knife The plate fixes the third blade and the second blade relatively, so that when the size of the flexible circuit board changes in a certain direction, the third blade of the die can be adjusted to change the size of the flexible circuit board. Cutting to remove the preset margins around the flexible board. The die can be used for flexible boards of various sizes, reducing the cost of using multiple die; and eliminating the need to change the die repeatedly, Section 099112811 Form No. A0101 10 pages / a total of 18 pages 0992022671-0 201136725 about time and labor costs 'and thus reduce the cost of flexible circuit board production.
