Description of the Invention: [Technical Field] The present invention relates to a sheet for drilling processing, which can be applied to a drilling process of a printed circuit board, and contributes to efficient production of a high quality printed circuit board . [Prior Art] The function of the printed circuit board is to attach electronic components to the electronic components and to electrically connect the components to each other, which is an important internal component of the electrical product. When the printed circuit board is manufactured on the 1st eve, after the slab is laminated on the Backup Board, the Entry Board is placed on the uppermost substrate, and the substrate is inserted through the substrate. Hole processing, at the same time, a small hole is formed in the front surface of the substrate by using a drill to form a small hole in the substrate for a printed circuit board. 15 ^The cover plate usually uses a pure aluminum plate without a lubricating layer, for example, Αίοοο • 'Ming material of the series material, mainly for drilling the hole on the printed circuit board substrate, preventing the substrate from being damaged and reducing the burr (burr ) and improve positional accuracy. In recent years, since electronic components are mounted on a printed circuit board at a high density, the circuit line width and spacing are reduced, the speed of the drilling processing equipment is increased, and the number of layers of the substrate is gradually increased, so that drilling is required. A small hole with a diameter smaller than Π1ΓΠ. ...When a pure aluminum plate without a lubricating layer is used as a cover plate, it is easy to affect the positional accuracy and cause damage to the Driu Bit after passing through the small hole. Due to the use of aluminum sheets, the knives of the drill bit are often broken or the burs themselves are broken, so that the drilling of the printed circuit board cannot be used to increase the number of layers of the substrate, thus reducing the efficiency of the drilling process. In addition, the slipping action of the drill bit on the surface of the substrate causes it to be unable to drill holes in the exact position. Another problem is that the surface of the inner wall of the small hole becomes rough, causing problems in the subsequent plating process. In order to prevent breakage and breakage of the drill cutter, to prevent roughening of the inner wall of the small hole, and to improve the positional accuracy of the small holes on the substrate, it has been developed to provide a metal plate by attaching a lubricating material to one side of the substrate. A resin-coated metal sheet having a lubricating layer formed on one surface thereof. For example, 'Korean Patent Publication No. 2002-0018984 discloses a printed circuit board for drilling an organic material layer having a thickness of 2 to 300 μm on a surface of a metal foil having a thickness of 5 μm to 500 μm. Lubricant sheet. Specifically, the organic material layer of the lubricant plate for drilling a printed circuit board is a mixture containing a polyether ester, a solid phase water-soluble lubricant, and polyethylene glycol; 15 or a polyether ester-containing solid phase water-soluble A mixture of a lubricant and a liquid phase water soluble lubricant. Further, the Korean Patent Publication No. 2003-0036041 discloses a drilled cover sheet material containing a water-soluble resin and a water-insoluble lubricant, which is bonded to a metal falling surface thereof. In addition, the Korean Patent Publication No. 2005-0056149 discloses a resin-coated metal plate in which one side of a metal plate is coated with a thermoplastic resin, and the thermoplastic resin herein is substantially water-insoluble, and the thermoplastic resin measured according to JIS Κ7121 specification, The maximum melting temperature is 6 ° C to 120 ° C, and when the thermoplastic resin is melted at a temperature of 150 ° C, the melt viscosity is maintained at lxl 〇 3 at a shear rate of 200 mm / 6 1360476 seconds. In the range of ixi 〇 4 poise (p〇ise), it is maintained in the range of 5x102 to 5x103 poise in the case of 3000 mm/sec. 'The hardness of the thermoplastic resin is measured according to JIS K7125 by D Durometer. In the range of 20 to 45. 5 The material disclosed in the above technique has in common that an organic substance layer (lubricating layer) is provided in order to impart lubricity to one side of the metal layer. In the drilling process of the printed circuit board, the surface in contact with the copper foil as the substrate is a metal layer, and when the metal layer of the material for the drilling process is in contact with the copper flute as the substrate, due to the copper foil and the plate The close contact 10 is weakened, thus forming an air layer at the gap thereof, and a slight slip phenomenon occurs due to the inability to absorb the rotational vibration of the drilling machine. This phenomenon will cause slippage during the drilling process of the drill bit. When the lubricant substance from the lubricating layer is mixed with the substrate chips generated after drilling the small holes and is sucked in (pumping chips), it is not smooth. The ground discharge is again blocked by the substrate contact surface of the drill plate 15 and is re-buried, so that the drilling machine malfunctions and the result of the designed hole machining operation cannot be performed. SUMMARY OF THE INVENTION In order to improve the close contact between the board and the substrate for the drilling process, and to obtain a high-quality method, the applicant finds out if the method of improving the drilling process of the printed circuit board is The close contact between the back surface of the metal layer (that is, the side of the organic material layer mentioned below) is greater than the specific value in the sliding test, and the close contact between the sheet for the drilling process and the substrate can be improved. The present invention can be accomplished by preventing slippage between layers and entering 1360476. Therefore, it is an object of the present invention to provide a plate material for a drilling process which can prevent the α phenomenon between the plate material for a drilling process and the substrate in the m of the printed circuit board. The 加 孔 疋 疋 provides a boring process sheet that can improve the straightness of the drill bit in the drill hole of the printed circuit board. The drilling process for the drilling process can maintain the wear resistance of the drill bit. The layer problem can be solved by the organic material containing the lubricating function. The sheet is a t_value at the time when the tilting test is carried out by the Slip method, and the side of the metal layer = P with respect to the organic material layer starts to slide. The hole is used to strengthen the process sheet. The method of scooping the ΐ ΐ 当 为 为 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本The anti-slip layer comprises a group consisting of acetamethylene, ethyl acetate, acetic acid, ethyl acrylate and ethyl methacrylate, and at least one monomer is selected to be a polymer or Copolymer. More suitably, the back side of the layer of the organic substance layer or the anti-π layer having a lubricating function includes a colored layer. 20 1360476 It is more appropriate to have the surface of the metal layer undergo a surface modification process. It is more appropriate that the surface roughness (Ra value) of the back side of the metal layer is greater than 0.3 μm. The invention is further illustrated below. The plate for drilling processing of the present invention forms an organic substance layer (lubricating layer) having a lubricating function on one side of the metal layer, and when the tilting test is performed by a sliding method using a sliding tester, the back side of the metal layer (ie, The tan0 value at the time of starting to slide relative to the copper foil relative to the side of the organic material layer is greater than 20. 〇 15 In the sliding test, the _ value when the back side of the metal layer began to slide relative to the copper box was greater than 20. When the surface of the oil-component wire plate is stored with a large amount of miscellaneous force, the positional accuracy can be improved during the processing, that is, the prescribed cpk value can be satisfied. When the thickness of the back side of the metal layer is greater than 20, the _ value of the final fabricated hole-added I-process sheet is between 2" and 2.4, showing excellent positional accuracy. The above tan0 value table * has a heterogeneous force greater than the intrinsic surface force between the metal layer (i.e., the commonly used 2 metal) and _. If the back side of the metal layer starts to slide relative to the steel line in the π motion test, the value of _ is less than 2 〇. Therefore, it is impossible to prevent the drilling process (4) sliding between the plate and the copper (four) substrate. The drilling process sheet of the present invention containing the lubricating layer on the metal layer is not limited to the tane value of the back side of the metal layer in the sliding test. In accordance with the above 20 == square: 'For example, when a resin layer is formed on the back surface of the metal layer, and the square material is limited to form a resin layer, as long as a tane value that satisfies the above range can be obtained, it does not count, 』 The lamp 迷 迷 4 4 4 4 4 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , "). The oil-soluble, water-insoluble polymer and water-soluble, water-insoluble lubricant can be used for the lubrication of the material processing process. As a specific example, the water-soluble organic substance layer may be a delta containing polyacetal: a solid/mesh and a number average molecular weight of fine poly to _, or may be a polydecyl ester, a solid phase water-soluble A mixture of a lubricant and a liquid phase water soluble lubricant. A more appropriate approach is that the organic layer is a water insoluble. Because if it is a water-soluble resin, it will reduce the tight adhesion between the resin and the metal layer, and the difference in absorption rate with the metal is also large, which may cause the metal plate to lie and hide. Therefore, the resin of the wire should be a water-insoluble or slightly water-soluble "substantially water-insoluble" organic substance layer. The thickness of the lubricating layer should be maintained within the range of 20 to 300 μηη. If the thickness is too thin, it will not function as a lubricant during drilling and the role of the discharge chip. Otherwise, if the thickness is too thick, the drilling process will be reduced. The precision may cause damage to the drill bit. If the anti-slip layer of the sheet for drilling processing of the present invention has the same composition as the lubricating layer 1360476, the non-aqueous component of the anti-slip layer should be the same as the preferred non-aqueous component of the lubricating layer. The anti-slip layer not only improves the close contact between the sheet and the substrate, but also has the function of a buffer layer to reduce the vibration of the drill bit, thereby improving the straightness when drilling a hole. Increasing the straightness during drilling can reduce the phenomenon that the chips are reburied in the substrate during the drilling process, which means that the smear can be reduced to improve the quality of the substrate after drilling. It can also act as a buffer during drilling to reduce bit wear. In terms of the workability of the hole processing, the thickness of the above non-slip layer should be less than 50 10 μm. More suitably, the resin layer is a polymer or a copolymer composed of ethacrylic acid or ethyl methacrylate monomer. When manufacturing the sheet for drilling processing of the present invention, the bonding of the metal layer, the lubricating layer and the anti-slip layer may be performed by any one of dry lamination, wet lamination and high-temperature lamination, and a known bonding may be used. The agent is bonded. For example, the adhesives for dry laminates on the market include acrylics, amines, and gs-based adhesives, and adhesives for thermosetting laminates include ethylene-vinyl acetate copolymer resin, dilute hydrocarbons, and rubber (four). As long as it is appropriately selected among these adhesives.

2Q 比此外,當本發明的鑽孔加工製程用板材的金屬層之兩 面皆具有樹脂層時,若潤滑層與防滑層的組成成分不同, 則在準備鑽孔加工作業時,由於需要區分板材的上下兩面, 因此在潤滑層或防滑層中會加上著色層。 本發明也可以在樹脂層的組成成分中加入防靜電性 11 1360476 能’以避免因靜電所引起的微細灰塵吸附或鑽孔加工設備 的錯誤動作。 此外,使金屬層背面的tan0值符合本發明之要求的其它 方法為,在不另外添加樹脂層的情形下,透過物理或化學 5的方法對金屬層背面進行表面改質。 此日π ’物理方法可以使用粗縫化(patterning)或浮雕處 理等方式’但不限定於此;化學方法可以使用酸處理的表 面改質,但不限定於此。使用物理或化學方法對金屬層背 面進行表面改質時’應使金屬層背面的表面粗链度大於0.3 ίο μιη。若其表面粗糙度小於〇 3从111時,金屬層背面之仏沾值將 無法介於上述範圍。 表面粗糙度指的是,使用表面粗糙度量測儀(小阪 SE-30C產品)所量測的表面粗縫度。 鑽孔加工製程用板材的金屬層通常使用鋁製成,最好 Μ使用純度達99.0%的純鋁。上述金屬層的厚度應介於5到 5〇〇 μιη的範圍内,3〇到3〇〇 μιη較佳,5〇到2〇〇卿則更 佳。 如前所述,本發明之具有潤滑功能的有機物質層與金 屬層之鑽孔加工製程用板材,該板材之金屬層背面開始相 2〇對於銅ν§面進行滑動時的加❻值大於一定值時,可以提高 ,與基板之_緊密接觸性,並防止其與基板之間形成= 乳層,進而改善鑽孔加工時的綱直進性,減少鑽頭振動, 因此可以維持鑽頭的耐磨耗性並延長鑽頭更換週期,亦可 防止鑽孔屑片流入基板與金屬層之間以免除出現錯誤動作In addition, when the metal layer of the sheet for drilling processing of the present invention has a resin layer on both sides, if the composition of the lubricating layer and the non-slip layer are different, it is necessary to distinguish the sheet material when preparing the drilling operation. Upper and lower sides, so a colored layer is added to the lubricating layer or the non-slip layer. The present invention can also incorporate an antistatic property 11 1360476 into the composition of the resin layer to avoid the adsorption of fine dust due to static electricity or the malfunction of the drilling apparatus. Further, another method of making the tan0 value of the back surface of the metal layer conform to the requirements of the present invention is to surface-modify the back surface of the metal layer by physical or chemical means without additionally adding a resin layer. The π ′ physical method may be a method of patterning or embossing, etc., but is not limited thereto; the chemical method may be modified with an acid-treated surface, but is not limited thereto. When the surface of the metal layer is surface-modified by physical or chemical means, the surface of the back side of the metal layer should be thicker than 0.3 ίο μιη. If the surface roughness is less than 〇 3 from 111, the 仏 value of the back side of the metal layer will not be within the above range. The surface roughness refers to the surface roughness measured by using a surface roughness measuring instrument (Kobe SE-30C product). The metal layer of the sheet for the drilling process is usually made of aluminum, and it is preferable to use pure aluminum having a purity of 99.0%. The thickness of the above metal layer should be in the range of 5 to 5 〇〇 μηη, preferably 3 〇 to 3 〇〇 μιη, and more preferably 5 〇 to 2 〇〇 〇〇. As described above, according to the present invention, the organic material layer having the lubricating function and the metal layer are used for the drilling processing process, and the back surface of the metal layer of the material is the same as that of the copper surface. When the value is increased, the contact with the substrate can be improved, and the formation of the = milk layer between the substrate and the substrate can be prevented, thereby improving the straightness in the drilling process and reducing the vibration of the drill bit, thereby maintaining the wear resistance of the drill bit. And extend the bit replacement cycle, and also prevent the drilling chips from flowing between the substrate and the metal layer to avoid erroneous actions.
