た。 DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an anisotropically conductive sheet, particularly an anisotropically conductive sheet in which metal wires or metal fibers are oriented perpendicularly to the surface of an insulating material. A sheet made of an insulating sheet made of various thermoplastic resins or rubber materials with conductive fiber materials oriented in a direction perpendicular to its surface exhibits conductivity in the direction in which the conductive fiber materials are oriented; It is called an anisotropic conductive sheet because its insulation properties are maintained in the lateral direction parallel to the sheet surface, and it is used to provide electrical continuity between, for example, printed circuit boards and various electrical and electronic devices. It is said to be useful as a connector for However, conventionally, this anisotropic conductive sheet has been manufactured by mixing conductive fibers with an insulating material and then forming them into a sheet using an extruder or roll. The sheet materials obtained in this way are laminated, and then they are integrated by hot pressing. It is necessary to punch out shaped objects according to their purpose, and there is a problem that this is disadvantageous for the assembly of electronic parts, where assembly processing has been streamlined and continuous press machines have been widely introduced. Although it is not impossible to form this into a continuous sheet using the above-mentioned conventional method, this has the drawbacks of extremely low productivity and complicated equipment. The present invention relates to a method for manufacturing a continuous tape-shaped anisotropic conductive sheet that solves these disadvantages, and this involves mixing metal wires or metal fibers with an insulating material, and then forming the mixture into a disk shape. Injection molding is performed from the center of the mold in the circumferential direction to produce a disk-shaped molded product in which metal wires or metal fibers are oriented in the injection direction, and then this molded product is sliced along the circumferential direction. This method is characterized by obtaining a continuous sheet-like body. To explain this, the present inventors conducted various studies on continuous manufacturing methods for anisotropically conductive sheets, and found that
This is often done by slicing a disc-shaped molded product from its surface in the circumferential direction. To do this, an insulating material containing conductive fibers is injected radially from the center to form a disc-shaped body. Since the conductive fibers are oriented in the injection direction, it was confirmed that an anisotropic conductive sheet could be obtained as a continuous sheet by slicing it in the circumferential direction along the surface of the disk-shaped body. completed. The insulating materials used in the method of the present invention include polyolefin resins such as polyethylene and polypropylene, thermoplastic resins such as vinyl chloride resins and polyphenylene sulfide resins, unsaturated polyesters, phenolic resins, urea resins, melamine resins,
Thermosetting resins such as guanamine resin, natural rubber,
Examples include various rubber elastic bodies including synthetic rubbers such as ethylene-propylene rubber and siloxane rubber, but these may also be fluid and room temperature curable. Note that reinforcing fillers, extenders, plasticizers, pigments, dyes, solvents, curing agents, stabilizers, and the like may be added to these resins and rubbers as necessary. Next, the metal wires or metal fibers that are mixed into this insulating material include metal wires made of copper, brass, stainless steel, tungsten carbide, lead, solder alloy, etc., whisker method, whisker plating method, vapor deposition method, etc. Examples include metal fibers made of the same type of metal as the metal wires mentioned above, which are made by melt spinning, drawing, shearing, cutting, etc., but these are coated with gold or anti-rust to improve their environmental resistance. It may also be one that has been subjected to
However, since this metal wire or metal fiber needs to be blended into an insulating material by injection molding as described later, it has a diameter of 2 to 500 μm, preferably 15 to 50 μm, and more preferably 20 to 50 μm. 30μ
m, the length is 0.1 to 20 mm, preferably 1 to 10 mm,
More preferably 3 to 5 mm, aspect ratio (/
D) is preferably in the range of 5 to 200, preferably 80 to 120. In the method of the present invention, first, this insulating material and metal wire or metal fiber are mixed uniformly, but this can be done using a kneading machine such as various mixing rolls, and these mixing ratios are adjusted to match the desired sheet size. In order to keep the electrical conductivity density and resistance value sufficiently low and stable, the metal wire or metal fiber is added in an amount of 10 to 500 parts by volume, preferably 30 to 100 parts by volume, more preferably 100 parts by volume of the insulating material. is 50~
The range is preferably 80 parts by volume. This mixture is then injection molded to form a molded product in which the metal wires or metal fibers are oriented in the direction of injection. The mixture must be injected into the mold while rotating to form a disc. This injection molding is carried out, for example , by charging the above mixture into a hopper 2 of a rotary molding machine 1 and injecting it from an injection plunger 3 into a rotating mold 4, as shown in FIG. However, the disk-shaped molded product obtained by this method has metal wires or metal fibers oriented in the injection direction, as shown in FIG. Note that the size and thickness of this molded product are arbitrary, but for example, for the sheet forming process described later, the diameter should be 50 to 500 mm and the thickness should be 0.5 to 0.5 mm.
The thickness is preferably 20 mm, preferably 1 to 5 mm. Next, as shown in Fig. 3, this disc-shaped molded product is laminated in an appropriate number of sheets as necessary and then sent to the sheet forming process. During this lamination, an appropriate adhesive is applied to the surfaces of these molded products. For example, it is sufficient to apply a room-temperature-curable silicone rubber and laminate it under pressure. It is said to be a ribbon-like sheet.
This sheeting process can be carried out by bringing a cutting blade into contact with the outer periphery of the disc-shaped molded product and peeling off the skin using a known method, as shown in Fig. 4, for example. Since the cutting blade contains hard metal wires or metal fibers in a soft matrix, it is preferable to use a so-called rotary blade that rotates a carbide round blade at high speed as the cutting blade. The thickness of the sheet-like product thus obtained can be adjusted arbitrarily by contacting the cutting blade with the disc-shaped molded product, but usually this is 0.1 to 1 mm.
Since it is also obtained in the form of a continuous ribbon, it may be wound onto a reel or cut into appropriate lengths to produce products. The sheet-shaped molded product obtained by the method of the present invention is cut from the surface of a disc-shaped molded product in a direction perpendicular to the metal wires or metal fibers oriented in the injection direction in the matrix. So,
This is because metal wires or metal fibers are oriented and dispersed in the thickness direction of the insulating material, so this sheet has good electrical insulation properties in the creeping direction, but has high electrical insulation properties in the direction perpendicular to the plane. It is anisotropically conductive and has a ribbon-like continuous sheet shape, so it can be advantageously used in the assembly of electronic parts, which is carried out using continuous pushing machines. The method of the present invention has the advantage of being able to produce it industrially easily and continuously. Next, examples of the method of the present invention will be given. Example Silicone rubber KE171-U [manufactured by Shin-Etsu Chemical Co., Ltd.]
Product name: 100 parts by weight of the curing catalyst C-8 (made by the company)
After adding 2 parts by weight of (trade name) and kneading for 5 minutes using two rolls, 65 parts by volume of short brass fibers having a diameter of 30 μm and a length of 3 mm were added thereto, and these were kneaded for 5 minutes using a mixing roll. Next, this was heated to an injection pressure of 150 using a rubber injection molding machine RJ-150 (manufactured by Kawajiri Hydraulic Machinery Co., Ltd., trade name).
Cavity dimension maintained at 175℃ at Kg/ cm2 is 150mm
A disc-shaped molded product was injected into a disc-shaped mold with a diameter of 2 mm and a thickness of 2 mm for a vulcanization time of 2 minutes, and then a room-temperature-curable silicone rubber composition KE-42RTV [manufactured by Shin-Etsu Chemical Co., Ltd.] was applied to the surface of the disc-shaped molded product. , trade name] to a thickness of 50 μm, layered to form a molded product with a total thickness of 20 mm, and cold-pressed.
It was left under a pressure of 10 kg/cm 2 for 24 hours. Next, this molded product was sliced into 0.3 mm slices at 1200 RPM using a rotary blade slicer equipped with a 200 mm diameter carbide round blade made by Toshiba Tungaloy.
When I made a sheet, the resistance value in the parallel direction was
A continuous anisotropically conductive sheet having a resistance of 6.2×10 12 Ω and a vertical resistance value of 50 mΩ/mm 2 was obtained.
