Description of the Invention: [Technical Field] The present invention relates to the field of cutting technology, and in particular, to a method for cutting an adhesive film for a circuit board. [Prior Art] At present, the printed circuit board (PCB) and its components are mainly formed by die cutting. The die cutting method is mainly divided into a steel die and a wood die cutting method. Although the die cutting method can save cost, the cutting precision is low. Specifically, the cutting precision of the steel knife die method is 0.1 mm, and the cutting precision of the wood knife die is ±0.2 mm, which will make the cutting body to be cut. The actual size and the theoretical size are quite different, and the tool needs to be changed frequently. For example, when cutting the adhesive film for the circuit board, the adhesive layer of the adhesive film needs to be cut off together with the release film, and then Both are used in the subsequent press-fit process. When the adhesive film 26 is cut by the die cutting method, as shown in FIG. 2, the existing die cutting method can cut the adhesive layer 25 of the adhesive film 26 and the release film 24, but is at a high speed. The state of the tool 21 will contact the table 22 of the cutting device, causing the table 22 and the tool 21 itself to be damaged, which results in a shortened service life of both, so that the cutting device is scrapped in advance, thereby increasing the production cost in disguise.

The machine includes a blade and a second knife:: knife!; machine for cutting 'the blade cutting step 1. The neck isolation gland method mainly includes the following steps: 9. The film is separated from the film, and the spacer is fixed on the table; The film is cut with the cutting depth of the separator to cut the film, so that the thickness U of the film and the separator is less than the thickness of the film to be cut first, and the height can be full; =;:: 2: The cutting precision is better than the cutting method of the die cutter. Secondly, the isolation film is provided on the workbench of the technical solution, which can avoid the blade scratching the table in 5 w, causing damage to the blade and the workbench. This effectively increases the service life of the cutting equipment. [Embodiment] Hereinafter, a method for cutting an adhesive film for a circuit board provided by the present technical solution will be described in detail with reference to the accompanying drawings and embodiments. Referring to Fig. 1', a schematic diagram of a cutting method of a method for cutting a magnetic film provided by an embodiment of the present technical solution. This method uses a blade cutter to cut. △ 'Blade cutting machine (not shown) includes blade U and working X blade cutting machine for blade cutting in the field of circuit board production: 4 L 'two piece 11 can be driven by the drive system and control system, etc. Control, °. That is, cutting in and out. In this embodiment, an FC4200-50 type cutting machine manufactured by Graphtec Co., Ltd. is used. Throne Tungsten = Sheet 2 is a super-steel material knives, preferably the main component is carbonized · '-, medium, tungsten carbide content of not less than 90%, and less than the full idling cutting requirements for blade cutting performance. In this embodiment, a CBl5U 5sp type blade manufactured by Graphtec Co., Ltd. is used. : The work table 12 is used to place the body to be cut. The workbench has a static adsorption function, so as to cut the front of the operation, the electrostatic adsorption of the cutting body will be directly attached to the workbench i2 without having to set a special card body and in the cutting process, the blade U Parameters such as movement rate, motion, and depth of cut can be controlled and adjusted by adjusting the drive of the blade cutter and the control system. The example method includes the following steps: Workbench 12. For the isolation membrane 13, The separator 13 is fixed to the Δ, preferably the electrostatic film, to be further enhanced: 12 electrostatic adsorption of the separator 13 is performed on the table 12 as the blade 11 moves. "Film 13 (four) preferred The thickness is about mm ~ g plastic; such as: film, polyolefin thin tantalum or polyethylene film. The adhesive film for the separator and the circuit board usually comprises a release film and a paste; the film and the protective film are respectively located on opposite sides of the layer: a surface for protecting the adhesive layer. Ten watch film: Before the film is cut, the adhesive film is protected first, and the adhesive film 16 to be cut as shown in Fig. 1 is formed. The adhesive film 16 includes the release film 14 and the adhesive layer 15 . The 4 (4) 14 is a release film commonly used in the field of circuit boards, such as a polyethylene terephthalate release film. - The adhesive layer 15 is composed of a (4) agent commonly used in the field of circuit boards, such as an epoxy type adhesive or an acrylate type adhesive. The release film 14 of the adhesive film 16 to be cut is attached to the separator 13. The release film 14 is fixed to the separator 13 by electrostatic adsorption of the table 12 and the separator 13 to prevent the release film 14 z and the station layer 15 from moving along the blade 11 during the cutting. 13 moves. In addition, the protective film may not be damaged or contaminated by the adhesive layer 15 during the cutting process before the cutting operation. At this time, wait for j to avoid). The protective film (not shown in Fig. 1) can be separated from the release film 14 of the adhesive film 16 to achieve the adhesion of the adhesive film 16 to the separator 13.

The capture rate of the blade η is preferably 1 In addition, before the cutting operation, the film should be adjusted to the cutting force and the blade: to be: cut = film protection release film, adhesive layer The sealing depth of the protective film is greater than the thicker sound of the layer and the protective film and the isolating film than the release film, and the adhesiveness is high, the brightness is flat, no burrs, and the cutting precision is And the sample is cut 8 (3) 3235. This lean example uses a blade cutter with a lower price than the die cutter and the laser cutter 2 as the cutting device, and the blade as the cutting tool can meet the precision requirements of the flexible circuit board sample preparation. And the cost is reduced. This embodiment can be avoided by providing a separator for the workbench of the cutting machine. During the cutting process, the blade scratches the workbench, causing damage to the blade and the workbench, thereby effectively improving the service life of the cutting device.
