Description of the Invention: [Technical Field] The present invention relates to a printing screen and a manufacturing method thereof [Prior Art] / Directly plays an important role, it is realized =: oil: ... board field - precision coating The essential. The circuit board, circuit board, solder, etc. are placed directly on the screen with the screen printing ink, glue and solder equal to the squeegee =: below' to apply the oil to the predetermined area on the board. Screen printing of the tooth version The production accuracy of the screen printing pattern of the printing screen is closer (4). The printing screen is usually made of , or p, or made of metal. In the production: wide, silk, metal mesh, two methods of mechanical drilling, currently there are chemical = chemical method, two =; version = metal film on the corresponding screen printing. I, 颂 、, etch in low, the film in the production process, the shrinkage ^ / method 2 for the length of the process, the efficiency will cause the metal sheet of the screen printing slaughter == ginseng and money when the side money through the mechanical drill The hole machine is directly to the whole; 7乍 has low precision. The mechanical drilling method is based on the low precision of the screen printing pattern and forms a screen printing pattern. The method of burrs, thereby affecting the back center... the screen printing pattern of the slab is easy to form and the method cannot process the miscellaneous screen printing. 'Unable to adapt to precision printing, and 200900247 As the circuit board gradually develops in the process of miniaturization and high-path board production, the printing network produced by the grid version method can print a printing network. Due to the accuracy of screen printing patterns, you can't meet the needs of high-density circuit board production, _, scrapped, which affects board production yield.曰 笔 笔 笔 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 。 。 。 。 。 。 。 Hereinafter, a printing screen and a manufacturer thereof will be described as an embodiment of a printing screen, which comprises a screen frame, a screen and a two-screen metal sheet, the screen end being disposed on the frame, the metal sheet The screen printing pattern of the metal sheet fixed to the screen = is ablated by laser, and the screen printing is +0.005~+0.02 mm or _〇.〇2-0.005 mm.

The metal pattern of the printed pattern is compared with the prior art. The printing screen is formed by laser firing (four), and the precision of the screen printing pattern is +〇〇〇5~+〇〇2 mm-0.02~-0.005 mm. The high-precision printing screen facilitates high-precision screen shank for precision screen printing, which can effectively prevent the net printing from being printed: the second pure scrapping, and improving the board production yield. The printing screen printing method can effectively save costs and improve production efficiency. 200900247 [Embodiment] * ^Combination and implementation (4) The printing screen r provided by the technical solution and its manufacturing method are further explained. Please see the picture! Shown is a printing screen 100 provided by an embodiment of the present technical solution. The printing screen (10) comprises a frame 11 丝网, a screen 12 〇 and a metal sheet. The frame m can be a metal frame, a wooden frame or a plastic frame. The shape of the 、 frame 110 can be designed according to actual needs during use. In this embodiment, the frame 11G is a rectangular metal frame, such as a metal frame. The peripheral edge of the screen 120 is connected to the inner side of the frame 11〇 so that the screen 120 is disposed at the end of the screen. The screen 12 has a certain degree of elasticity and tension to provide the specific deformation required for the printing screen 100. The screen (10) may be a polyester mesh, a nylon mesh or a wire mesh or the like. This embodiment 5 is a polyester screen. The metal piece m can be a film or the like, and the shape and thickness of the metal piece 13 can be designed according to the actual needs of the material towel. In the embodiment, the metal piece 130 is a rectangular piece having a size smaller than the size of the mesh frame, and the thickness of the metal piece 130 can be 〇3 mm, which can be used for the circuit board ink plug. The metal piece 130 has a screen printing pattern 131 formed on a through hole of a metal piece 13A having a cross-sectional shape not limited, and is formed by using a laser-burning metal piece 130. The fine print of the screen printing pattern m, that is, the position where the screen printing pattern 131 is theoretically formed on the metal plate 13〇 during the shot cutting and the position where the screen printing pattern 131 is actually formed on the metal plate 13〇 The error is +0.005~+0.02 mm or -0.02~-0.005 亳m. The metal 4130 is fixed to the screen 12 〇. In this embodiment, the surface of the metal sheet (10) 200900247 is directly attached to the surface of the screen 12, and preferably, the genus is 嗜! . The film 130 can be fixed to the center of the surface of the screen 12. Please refer to FIG. 2A to FIG. 2C. The manufacturing method of the printing screen 100 provided by the embodiment of the present invention includes the following steps. In the first step, as shown in FIG. 2A, the gypsum full eyebrow tick is provided to the sub-piece 130, and the screen printing pattern 131 is formed by using the laser-fired metal piece m', and the screen printing pattern is 005~+0.02 mm or _〇· 〇 2~_〇〇〇 5 mm. The degree is the Τ laser (four) 丨 line emission beam directly on the gold w 13G 仃H open> 纟 corresponds to the screen printing area of the printed area of the board. The laser cutting system can scan the circuit board through the image sensor, and the predetermined printing is processed by the computer to form a predetermined printing area corresponding to the circuit board. According to the image data, the laser beam is emitted by the laser cutting system, and the The area corresponding to the predetermined printing area of the circuit board is subjected to cooking = sub-metal m to form a screen printing pattern i3i corresponding to a predetermined printing pattern or pattern of the board. This process can be used for nuclear network printing: the accuracy of the temple opening. The accuracy of the screen printing 帛131 is 1 when the laser cutting is performed, and the screen printing pattern 131 of the predetermined printing area of the stylus board is theoretically formed on the metal plate and the screen printing 1131 is actually formed on the metal plate 130. The error between the positions is +0 005~+0 02 mm or ^2~-0.005 pens. The laser used for burning money can be a carbon dioxide laser or a purple field shot such as Rui Ji Shao Shi Quan Shi (10) kiss like a coffee: plus (a) coffee Aluminum ^ called toe to the solid laser of the medium. The energy density of the laser beam is controlled according to the screen printing m rule: the material and the thickness of the laser beam, so that the sub-plate 130 is directly laser-fired (four) into the screen printing pattern 131. 200900247 In the first step, as shown in Fig. 2B, a frame 11 and a screen are provided, and the screen 120 is disposed at the frame u〇. • Attach the perimeter of the '''糸 net 120 to the inner side of the frame i〇. The screen 120 can be attached to the inner side of the frame by gluing and can be fixed by other means. j 2〇 is stretched over the frame 110. The screen 12 is stretched over the frame 11 and has a constant elasticity and tension to provide the specific deformation required for the printing screen 100. In the first step, as shown in Fig. 2C, the metal piece 130 having the screen printing pattern 131 is fixed to the surface of the screen 12. The metal piece 130 is fixed to the screen 12 by gluing, and the surface of the metal piece is directly attached to the surface of the screen 120, and is fixed by glue glue. The glue can be applied before the metal piece 130 is attached to the screen 120. The surface of the metal sheet 130 and the screen 12 can be applied to the surface of the screen 12 and the metal sheet 130, or simultaneously coated on the surface of the metal y 13 〇 and the screen 120. A surface that is bonded to the wire mesh 12G and the metal piece 13 (). The position at which the metal piece 130 is fixed is not limited. Preferably, the metal piece (4) can be fixed to the center of the screen 120. In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is legally issued. However, the above is only the preferred embodiment of the present invention = it is not possible to limit the scope of the patent in this case. Equivalent modifications or variations made by persons familiar with the present invention in accordance with the spirit of the present invention are intended to be included in the scope of the following claims.
