Description of the Invention: [Technical Fields of the Invention] For the drilling circuit of the printed circuit board (frenched circuit) or the lubricating auxiliary plate for the high-speed dial forming process, the present invention does not require a conventional organic primer (or a primer, a primer) Instead, surface chemistry or electrochemical treatment is used to form an oxide layer on the surface of the metal as the interface between the metal substrate and the lubricant layer to form the desired bonding properties. The surface of the treated metal substrate nanoporous oxide layer has the function of holding the drill pin to prevent the drilling needle from sliding and shifting, thereby improving the drilling precision. Since there is no undercoating of the thermosetting compound between the lubricant and the nameplate, there is no possibility that the undercoat is burnt due to high-speed friction to contaminate the drill needle or the insoluble rubber compound remains on the wall of the hole. After the surface oxidation treatment of the aluminum plate of the present invention, the surface hardness and the gold are increased in rigidity and are not easily bent and deformed; when used as a bottom plate for drilling, the burr of the exit surface of the drill hole can be reduced. Subsequently, the water-soluble hot-melt lubricating layer is coated on the oxide layer, which can effectively reduce the friction heat and wear of the burr tip and prolong the life of the bur. Therefore, the technique of the present invention can be simultaneously applied to a cover plate and a backing plate for assisting high speed drilling.

It has been widely used in portable electronic products such as mobile phones, laptops and digital cameras. However, in the drilling process of a flexible printed circuit board, if a conventional cover plate is used, it may be difficult to break the needle with the soft plate to be drilled due to insufficient rigidity. The material of the hard printed circuit board (1) is traditionally epoxy resin board or phenolic resin board. However, the trend of high-order materials is halogen-free board, high glass transition temperature, Bismaleimide-triazole resin (Bismaleimid)

In addition, the hole diameter is smaller and smaller, and the hole diameter below 15 mm often faces problems such as insufficient drilling precision, rough hole wall, and broken needle. In addition to drilling, in addition to drilling, the high-speed list forming process is also often difficult to solve with the problem of sharp needle wear. These are the procedures for the maintenance of the thick copper circuit board, metal, glass plate, etc. A polymer lubricant auxiliary cover with a lubricating function is usually applied to improve the above problems. The drilling process of the printed circuit board, as shown in the figure, is provided with a drilling auxiliary cover above the printed circuit board (1), which is a metal substrate (2) and a lubricating layer (3) The high heat generated during the drilling is dissipated by the metal substrate; a drilling auxiliary pad (4) is added under the printed circuit board (1) to prevent the generation of the exit Burr; lubrication The agent assists in reducing the wear of the drill (5). There are several important purposes for using the Entry Board. 1. Reduce the number of copper foil faces caused by the drill entering and leaving the board. 2. Reduce the needle sway and make the drill tip easy to position. 4 201231195 3. Prevent Pressing or indentation of the pressure foot on the copper surface of the substrate 4. Assisting the chip removal and the burr heat dissipation 5. Reducing the wear or break of the bur (Breakage) Therefore, the important conditions for selecting the cover are as follows: 1. Yes A certain rigidity to prevent the cover from being up and down when drilling. 2. The surface of the drill has a certain elasticity. When the drill is drilled, the hole can be immediately recessed, so that the drill bit can be accurately aligned with the position to be drilled. Hole position accuracy 3. It should be smooth, flat and not bent, and there should be no pinholes to the surface. 4. High thermal conductivity, can quickly remove the heat generated during drilling, reduce the drilling temperature 5. Face the hard circuit The surface of the board can prevent the copper foil face from being disclosed in the Republic of China Patent No. 566064. The upper cover (or auxiliary cover) for drilling is prepared by a primer coating method, wherein the primer is a thermosetting glue. However, if the primer-free coating or the undercoat layer is too thin, the osmium-repellent agent on the substrate cannot be effectively adhered to the substrate, and the function of lubricating and positioning the auxiliary hole cover plate cannot be achieved. However, as the undercoat layer of the thermosetting adhesive, there is a problem that the drill pin is dirty, so the thickness is limited so as not to adhere to the groove of the drill pin, and the cutting ability causes the iron hole to be poor. Regarding the lubricating layer, the Republic of China Publication No. 200806099 patent patent disclosure revealed that the problem of residual bubbles in the resin layer and surface unevenness were overcome by adding isopropyl alcohol. In order to have good drilling results, in addition to the upper cover, the function of the sling plate is not important. The backing plate is placed on the lower layer of the board to be drilled and is the end point of the drill stroke. Its functions are: 201231195 h Prevent Extrusion Hair (Exit Burr) 2. Reduce the temperature of the drill needle, reduce the wear and break of the drill needle 3. Protect the drilling machine's countertop drilling pad The common material is wood pulp board Materials such as phenolic resin sheets or composite sheets, wood pulp boards or composite boards are manufactured on the basis of wood chips, and then mixed with an adhesive, which is pressed and hardened under high temperature and high pressure to form a flat board. Since the conventional backing plate is usually insufficient in hardness, it is impossible to effectively control the degree of the exit burr when drilling at a high speed and small aperture. The phenolic resin board is a board which is mixed with phenolic resin and kraft paper. Generally, the hardness is much higher than that of wood pulp board and composite material. It is used for drilling holes with smaller apertures, which can effectively prevent the export burrs, but the disadvantage is that the burs are caused. Excessive wear and environmental pollution after use. SUMMARY OF THE INVENTION At present, the commonly used drilling auxiliary cover plate covers the lubricant 1 on a metal plate or an organic plastic substrate, and the thickness of the substrate is generally 5 μm to 5 μm. When the drilled object or the molded article is easy to form burrs. § The thickness is over 500 μm, so it is difficult to remove the drill cuttings.

In order to avoid the poor adhesion between the lubricant and the substrate of the drilling cover, the slippery agent may be dislodged during storage, transportation or use, and the cover plate is firstly coated to increase the adhesion of the metal substrate. Then on the lubricant; in general, the primer is a thermosetting glue. SUMMARY OF THE INVENTION A primary object of the present invention is to overcome the drawbacks of the prior art auxiliary cover for drilling, which is caused by the primer coating of the thermosetting adhesive and the difficulty in recovering the metal substrate after use. In order to provide a non-thermosetting adhesive as a primer for the auxiliary coating for drilling, the technical problem to be solved is to improve the adhesion between the lubricating layer and the metal substrate and to improve the clamping ability of the metal surface to the drill needle, thereby improving Drilling accuracy. The present invention does not use an organic rubber as a primer, but performs surface treatment on one or both sides of a metal substrate to form an extremely fine oxide layer on the surface of the nanopore surface. The oxide layer on the surface of the nanopore surface can improve the interface adhesion between the lubricant and the metal plate, so that the lubricant and the metal substrate are not peeled off, and can fully lubricate the surface of the drill pin as the drill bit enters the hole. effect. The oxide layer on the surface of the nanopore surface enhances the surface hardness and also achieves the effect of pin clamping and positioning, avoiding displacement of the drill pin and improving the positional accuracy of the drilled hole. 2, the present invention provides an auxiliary plate for drilling for composite use, comprising a surface treated metal aluminum plate, a substrate (2) and a water-soluble solid lubricating layer (3); surface treated metal The surface of the substrate is a nanoporous oxide layer (6) 'having a thickness greater than 0.5 μm; a stray hardness greater than 3H. 201231195 = Equation = 1 is to observe the surface size of the nanometer pores after the oxidation treatment to the size of the secret size, the average diameter of the fairy between micro-I meters, the thickness of the oxide layer is between G. 5 microns and 3 Thick, 电子-type electron display (4) Observing the surface nanoporous oxygen θ formed, the mother 1 micron has 100 to 1000 holes. Tuto = invention proposed another auxiliary hole for composite use, such as the 3 ^ ^ ^ ^ which contains - double-sided surface treatment of the metal nameplate for the substrate surface treatment of the surface of the metal substrate to form nanoporous oxidation Layer (6), ^: There is a water-soluble solid lubricating layer (3) on the side. The burr (5) enters from the lubricating surface into the printed circuit board (1) through the other-side nanopore oxide layer (8); the nanoporous oxide layer (8) which contacts the printed circuit board (1) surface, which is higher in hardness than the untreated metal substrate Therefore, it is possible to prevent the hair from being generated when the drill needle (5) is withdrawn.

Dirty situation. The auxiliary board for drilling for the composite use of the invention can be easily washed and recovered due to the absence of the machine thermosetting rubber compound, thereby reducing the recovery cost of the metal sheet and achieving environmental protection and waste reduction. After the oxidation treatment, the rigidity of the aluminum plate is greatly improved, and it is not easy to be broken and deformed, so that the surface of the plate is very flat and applied to the surface of the object to be drilled, and the inching caused by the insufficient rigidity of the aluminum plate when the hole is in and out is reduced, causing the needle to run or break. problem. The auxiliary plate for drilling according to the present invention has a surface staggered hardness of more than 3 hours, and therefore, in addition to being a cover plate, it can also be used as a bottom plate for drilling to prevent the exporting hair. Compared with the conventional pad material, the auxiliary plate for drilling of the present invention has a lubricant on the surface thereof, so that it has a lubricating function and can greatly reduce the wear and break of the bit. Therefore, the present invention is a composite use drilling auxiliary material having a composite use. The water-soluble lubricating formula mainly contains alcohols (for example: propylene glycol, glycerol, hexanol, alcohol), polyethylene glycol and alcohol ether (for example, polyethylene glycol, polyethylene glycol, polyethylene glycol) a hospital ether, polyethylene glycol alkylamine ether, mixed with cellulose, polyvinyl alcohol, carbomer, polyvinylpyrrolidone (Polyvinylpyrrolidone 'PVP) and other coatings coated with a coating agent The homogeneous aqueous lubricant layer is applied to a thickness of ι〇_6〇 microns. Due to the production process of the water-soluble lubricating layer, the moisture drying rate is too fast, and the lubricant leveling property is sluggish, which causes the surface to produce 9 201231195. Lubricants are particularly prone to microbubble formation during manufacturing and coating processes, and the accuracy of the process is _<. u (4), for small-aperture drilling, the metal surface of the present invention is a nanoporous oxide layer, so that a large number of bubbles are more likely to be generated. If the method of adding isopropyl alcohol is disclosed in the patent application of the Republic of China Publication No. 2__(10), it is found that isopropyl alcohol is insufficient to improve the bubble problem of the lubricating layer on the nanoporous layer.

It can be seen from the above table that the non-porous oxide layer is formed between the lubricating layer and the metal substrate, and the good interface is better than the actual target of the anodizing treatment. Comparative Example 1 contained a primer, so the adhesion was good; otherwise, Comparative Example 2 did not contain a primer, and thus the force was poor. It has been confirmed that the nanoporous oxide layer effectively improves the adhesion between the lubricating layer and the metal substrate, and in particular, the effect of the anodizing treatment is good. According to the measurement data of the drilling accuracy, the auxiliary plate for anodizing provides good drilling precision, and the auxiliary plate for forming the film. Compared with the comparative example, the accuracy of the first embodiment and the second embodiment is obviously better. It is proved that the oxide layer acts as the interface between the lubricating layer and the metal, and in addition to improving the lubricating layer, the oxide layer of the hardness also has the effect of holding the needle at the same time. When the needle enters the oxide layer, 'the needle is swung, and then the needle is swung. Improve drilling accuracy. The auxiliary plate with the nanopore oxide layer of the first embodiment and the second embodiment has the above-mentioned good drilling precision, and there is no problem of the needle contamination and the broken needle; on the contrary, both of the comparative examples have the phenomenon of the needle contamination. In the second comparative example, there is even a broken needle. It can be seen from the roughness of the hole wall in the above table that the roughness of the first embodiment is low; the low wall roughness can improve the electrical reliability of the printed circuit board. (Embodiment 3) The present invention employs a procedure of water washing, degreasing, water washing, anodizing, water washing and drying using a 150 μm aluminum plate. An anodic current was applied to the aluminum substrate with sulfuric acid or chromic acid or oxalic acid as the electrolyte, the electrolysis temperature was 15 ° C, and the electrolysis voltage was 201231195 'electrolysis day (four) for 4 minutes. The thickness of the formed layer was reduced by an electron microscope, and the thickness of the layer was 5. The weight of the scale was 5.0 g/m2. The lubricating layer was formed in the same manner as in the embodiment, and the dry thickness of the lubricating layer was controlled at 15 μm. A double-layer circuit board with a thickness of 〇8 mm and a stack of 4 sheets using a double-male-imine-triazole resin. The general nameplate is used as the upper cover, and the above-made sheet is used as a high speed. Drill holes (four) to help the slab. a G. 2 mm aperture boring machine with a drilling machine of 200,000 rpm per minute, feed rate of 3.2 m / min, chip removal volume of 16 μm / rev, burr hole limit _ sniper, drilling, narrow Compare the size of the hair ends at the exit end. In addition, the other method is to reduce the rotation speed of 20,000 rpm after each boring until the broken needle occurs, and the lubrication capacity of the slab. The hardness test was carried out according to ASTM Eg363, using a pencil hardness and a load of 5 gram, and the obtained cobalt was as follows: Mingji auxiliary fascia Example 3 Comparative Example 1 Comparative Example 2 Surface treatment method Oxide layer Phenolic resin board Wood pulp board pencil Hardness 4Η-7Η 7Η 1Η Export hair (5000 shots) 2. 812 microns 2. 778 microns ^ 9. 623 microns · Lubricity test 812 hit 727 hits 500 hits the original wrong pen hardness 1Η to 3H; oxidation treatment After that, the hardness was increased from 4 Η to 7 Η; the hardness of the phenolic resin sheet of the comparative example was 7 Η, and the hardness of the wood pulp board was 1 Η. The higher the hardness of the mat, the shorter the measured hair is, and the durability of the hole is improved. From the test data, it is known that the oxidation reaction raises the hardness of the aluminum plate to a hardness close to that of the phenolic resin plate, so that the hair of the outlet is greatly shortened.
