Description of the invention (1) [. BACKGROUND OF THE INVENTION The present invention relates to through-hole wiring boards. Regarding the process for forming a conductive circuit on a printed wiring board, one of the processes is described in "Electronic Materials", October 1994, pages 4 2-4 6 where a conductive circuit is used by a hybrid Conductive powders, such as gold, silver, copper, carbon, etc., and binders, organic solutions and pastes obtained from optional additives are formed. In areas where high electrical conductivity is required, gold or silver powder has been used. A conductive paste containing silver powder is used to form printed wiring boards, electronic components, etc. or wiring layers (conductive layers) of electronic circuits and electrodes of electronic components because of their good conductivity. However, this paste is unfavorable when an electric field is applied to a high temperature and high humidity environment. Electrodeposition called migration occurs on an electronic circuit or an electrode, so that a short circuit occurs between the electrodes or wiring. Several methods to prevent migration have been adopted. For example, the application of moisture-proof materials on the surface of conductors or the addition of uranium decay inhibitors (such as nitrogen compounds) to conductive pastes have been proposed, but they are not efficient enough — I — — — — — (Please read the back first Please pay attention to this page before filling in this page) Order f Printed by Intellectual Property of the Ministry of Economy 笱 Printed by Employee Consumer Cooperatives [Invention Summary] The present invention intends to provide a through-hole wiring board, which does not have the disadvantages of the foregoing prior art, and allows easy formation of through-holes.

This conductive paste is not conducive to its price because silver powder is expensive. When silver-coated copper powder is used, migration can be improved and an inexpensive conductive paste can be obtained. However, when the silver coating is uniform and thick, migration cannot be improved. Furthermore, silver-coated copper powder is disadvantageous to the fact that soldering cannot be performed directly on the coating film of the conductive paste. The conductive paste using silver powder is not conducive to the loss of silver during soldering when it is soldered, making it impossible to obtain a sufficient joint. On the other hand, in the conductive paste using copper powder, the oxidation of the heated copper after curing is high. Therefore, the oxygen and a binding agent obtained in the air react with the copper powder to form an oxide film on the surface of the copper powder, resulting in a very low conductivity. Therefore, it has been revealed that the copper paste is used to prevent the paper size from applying the Chinese National Standard (CNS) A4 specification (210X297 mm) " I: n Order I n I (Please read the precautions on the back before filling in this Page) 1224129 Printed by the Intellectual Property of the Ministry of Economic Affairs and Employee Cooperatives A7 _B7_ V. Description of the Invention (5) Various additives added to stop the oxidation of copper powder, and it has stable conductivity. In terms of electrical conductivity, copper paste is inferior to silver paste and has poor storage stability. Furthermore, the traditional copper paste is not advantageous because soldering cannot be performed directly on the coating film of the copper paste. Because, as mentioned above, a known conductive paste cannot be directly soldered, so welding has been performed on the copper surface by subjecting the coating film of the conductive paste to an activation treatment and then electroless plating. Alternatively, copper plating is performed by using a coating film of a conductive paste as a cathode in a plating solution. However, this method is not practical if the interlayer bonding between the coating film and the copper-plated film is not reliable. Therefore, a circuit forming process can be greatly shortened by developing a conductive paste that can be soldered without electroless plating or electroplating. Therefore, the advantages of development are great. Solder is easily incorporated into some metals, but it cannot be incorporated into an adhesive. Ideally, in conductive welding, a coating film composed of a conductive powder is formed and the welding system is performed on the coating film. However, when the conductive powder is used alone, the reliability and working efficiency in forming a coating film are not sufficient. Therefore, the conductive powder is used after being used as a conductive paste for a binder. However, when the proportion of the adhesive is increased, its importance is equivalent to the reliability and working efficiency in forming the coating film, so the adhesive covers the conductive powder of the metal so that the solder will not contact the conductive powder. Therefore, the solder does not adhere to the conductive powder, resulting in low conductivity. In order to obtain the solder paste conductive paste, the composition of the paste must be as much as possible (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 specification (210X 297 mm) -8-1224129 A7 ____B7_ V. Description of the invention (6) (Please read the notes on the back before filling out this page} The composition of the contact copper foil. That is, the composition must be filled with conductive powder when the conductive paste is placed in a certain space. High, so that the adhesive only accounts for the total volume of the space formed between the conductive powder particles. However, when the proportion of the conductive powder as described above increases, the viscosity of the conductive paste increases greatly, making the production of conductive paste become It is difficult and the working efficiency of applying conductive paste is reduced. Moreover, because the proportion of the adhesive that can bind the particles of the conductive powder is very low, The strength of the coating film is reduced. Therefore, when bonding is performed by using a conductive paste, the conductive paste should achieve a good balance between solderability, conductivity, work efficiency, and strength. The method of using a conductive paste includes applying a conductive paste obtained by dispersing a conductive powder to an adhesive on the surface of a substrate, or filling the through holes with a conductive paste to form the one shown in FIG. 2. Conductive layer. In Fig. 2, reference numeral 1 denotes a conductive paste. As for another method of forming a conductive layer in each through hole formed in a printed wiring board, in this method, the conductive layer is formed by forming a copper-plated film 2 on each inner surface of the through hole, This is printed in the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs shown in Figure 3. Generally speaking, when the connection between the layers is formed using a filled conductive paste and filled with through holes, although the through holes Very small, but still requires a high conductivity. Therefore, the conductive paste should be inserted into the holes as much as possible 'so that the holes can be filled, as shown in Figure 4 for example. Therefore, a conventional conductive paste should increase the proportion of conductive powder. However, when the proportion of the conductive powder is increased, the filling characteristics of the pores are deteriorated. On the other hand, when the size of this paper is adhered to the Chinese National Standard (CNS) A4 specification (210X 297 mm) -9- printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1224129 A7 ___B7 V. Description of the invention (8) Called printed circuit The disadvantage of obtaining a multilayer circuit board is that the pores in the vias should be removed to increase the reliability of the vias 10 connected to the copper foil bumps 7, copper foil circuits 8, and printed circuits. In Figure 5, number 4 represents a conductive layer, number 6 is a jumper circuit, and number 9 is an outer coating. When a multilayer circuit board distributes conductivity to the vias by using a copper plating film formed on the inner surface of each via, the above disadvantages can be caused by forming a copper plating film on the inner surface of each via, and then forming A covering coating film 1 2 is removed on the conductive paste 1 of the filling hole, as shown in FIG. 6. However, this process is not desirable because it requires additional steps and therefore results in a higher cost. As shown in FIG. 7, there is another process including forming a copper-plated film 2 on the inner surface of each through hole to form a conductive layer and filling the space with a resin 1 3. The disadvantage of this process is that it causes high costs because it requires additional steps. Another process includes filling the via with a non-porous or substantially non-porous conductive material to ensure the conductivity of the via, and then forming an insulating layer and a printed circuit on the surface of the substrate. The disadvantage of this process is that the reliability of the connection is low, because the conductive material and the copper foil bumps of the through hole are connected to the edge of the copper foil. In order to avoid this trouble, the above-mentioned cover plating film must be formed. However, this process is not desirable because it requires additional steps and causes a high cost. In addition, when a multi-layer circuit board is produced using a silver through-hole wiring board, the wiring board has through holes filled with a silver conductive material (silver paste), and this paper size applies the Chinese National Standard (CNS) A4 specification (210X297mm) --------------- IT ------ ^ _ wl (Please read the notes on the back before filling this page) -11-1224129 A7 __B7 V. Description of the Invention (9) (Please read the precautions on the back before filling this page) When forming an insulating layer and printed circuit on the surface of a wiring board, the pores formed in the through holes reduce reliability.

The materials used in the present invention, the constitution of the present invention, and the like are described in detail below. This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 mm) -18- 1224129 A7 __B7 V. Description of the invention (17) (Please read the precautions on the back before filling this page) From the viewpoint of solderability, the exposed part From the viewpoint of oxidation, conductivity, etc., the exposed area of the silver-plated copper powder or copper alloy powder is preferably from 10 to 60%, more preferably from 10 to 50%, and most preferably from 10 to 30. %. There are many methods for coating copper powder or copper alloy powder with silver, such as alternative plating method, electroplating method, electroless plating method, etc. The coating is preferably performed by replacing the electric ore method, because the alternative electric ore method can provide a stronger adhesion between copper powder and copper alloy powder and silver, and cause a lower execution cost. Based on the weight of copper powder or copper alloy powder, and from the viewpoint of improving migration resistance, cost, and conductivity, the coating amount of silver on the copper powder or copper alloy powder allows the powder range to be preferably from 5 to 2 5 wt%, more preferably 10 to 2 3 wt%. Printed by the Intellectual Property of the Ministry of Economic Affairs 4¾ Employee Cooperatives When conductive powders have a small number of contact points, conductive powders tend to have a high impedance. In order to obtain a high conductivity by increasing the contact area of the conductive particles with each other, it is preferable to change the shape of the particles into a sheet shape or a sheet shape by applying an impact to the conductive powder. However, the use of a sheet-shaped or sheet-shaped conductive paste has higher viscosity, which makes its characteristics of filling into the holes worse than that of a conductive paste using a substantially spherical conductive powder. To reduce viscosity, it is sufficient to add a large amount of solvent. However, the addition of a large amount of solvent caused a reduction in the thickness of the coating film of the conductive paste after curing to a thickness corresponding to the volume of the solvent. In order to make the surface of the coating film into a sheet shape or a sheet shape, a honing system is sufficient. However, this honing is not desirable because it reduces the thickness of the film. Therefore, a conductive paste using a substantially spherical conductive powder is preferable in terms of working efficiency and conductivity of the conductive paste. ϋThe paper size applies Chinese National Standard (CNS) A4 (210X29? mm) ~ 1224129 A7 B7 V. Invention Description (24) (Please read the precautions on the back before filling this page) Even under the copper foil surface, borrow The recessed end of the through hole formed by excessively honing the conductive material (conductive paste) has high reliability in conductivity, because according to the present invention, the conductive material at the end of the through hole and the copper foil protrusion is a conductive material. Connect them. When the fins formed next to the through-holes are removed by, for example, uranium engraving after the through-holes through the substrate are formed, the connection between the above-mentioned filling holes and the ends of the conductive material of the copper foil protrusions Reliability is further increased. In the present invention, copper foil bumps and copper foil circuits can be formed by a method including forming a pattern on each copper box of a double-sided copper laminated board by using a resist, and using Saturate the solution and proceed to make a pattern. Meanwhile, when the through-holes are formed in advance, after forming a resist pattern on the through-holes by a so-called tent method, copper foil bumps and copper foil circuits can be formed by an etching method. 4 ^ 7a (printed by the Industrial and Consumer Cooperatives, Ministry of Economic Affairs) As a material used in the insulation layer, from the viewpoints of heat resistance and moisture resistance, a thermosetting insulation material composed of epoxy resin is preferred, but it can also be used. Insulation materials with thermosetting characteristics and u V curing characteristics can also be used. When the use environment is very soft, and the voltage generated by the printed circuit board is very low, a stack of V curing insulating materials can also be used. In the present invention, Regarding the adhesive added to each conductive material, filling the through holes and the conductive material used to print the circuit part of the copper foil, and the copper foil bumps and the insulating layer outside the unnecessary conductive part, preferably using a heat Solid resin group, which contains an epoxy resin and phenolic resin, or a single epoxide or paper size applicable to the Chinese National Standard (CNS) A4 specification (210 × 297 mm) -27- 1224129 employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative printed A7 _B7 V. Description of the invention (25) A polyethylene glycol, which is added to reduce viscosity, a coupling agent, a curing agent, etc. The ratio between epoxy resin and phenolic resin It is as follows. Among the conductive materials for filling holes, a composition with a high content of epoxy resin is preferable because the viscosity reduction and the solvent amount reduction are better. On the other hand, it is used for printing in the above. Among the conductive materials on the copper foil bumps and the insulating layer, a high content of phenolic resin is preferred to reduce the resistance of the printed circuit. This composition may include a solvent in a ratio of 10 to 2 5 W t %, As long as the solvent does not cause bleeding during printing. As for phenolic resins, known phenolic resins, phenolic resins, and other phenolic resins can be used. The ratio of epoxy resin and phenolic resin is better to make the ring The weight ratio of oxygen resin to phenol resin ranges from 10:90 to 90:10, more preferably 10:90 to 60:40. When the ratio of epoxy resin is less than 10 wt%, adhesion to copper foil The characteristics tend to deteriorate. When the proportion of the epoxy resin exceeds 90% by weight, the electrical conductivity is deteriorated. The conductive paste using a phenolic resin has a higher conductivity than the conductive paste using an epoxy resin. The reason is For curing phenolic resin The degree of shrinkage is higher than that of epoxy resins, and the volume of conductive materials using phenolic resins is greatly reduced, which increases the contact area and the possibility of conductive powder particles contacting each other.
