摘要： An inductor is constructed to achieve efficient formation of external electrodes, and exhibits high reliability of connection between the external electrodes and an internal conductor, and desired characteristics. In the method of manufacturing the inductor, a magnetic material formed by kneading a magnetic material and a resin is molded to form a magnetic material compact body in which the internal conductor is partially exposed from the external surface thereof, and then the surface of the magnetic material compact body is plated to form the external electrodes including a plated metal film and connected to the internal conductor. The surface of the magnetic material compact body is roughened, and then the external electrodes are formed via plating.

摘要： A method for efficiently and economically manufacturing an inductor using a resin based magnetic material, and a highly reliable inductor that is manufactured by the method, produces a unique inductor including a molded magnetic material member. An inner conductor is disposed in the molded magnetic material member and is exposed at a surface of the molded magnetic material member. The molded magnetic material member is formed using the resin based magnetic material in which a component that functions as nuclei for applying electroless plating is blended, followed by forming a selectively coated molded body so that the area not provided with external electrodes on the surface of the molded magnetic material member is covered with an insulating resin and applying electroless plating on the molded magnetic material member (selectively coated molded body), thereby eliminating use of a resist agent that is required in the conventional manufacturing method, as well as a resist agent removing step with an alkali and solvent and a removing step of the electroless plating film with an acid, by forming the electroless plating film as the external electrodes on the desired area.

摘要： A method for manufacturing an inductor is performed in such a manner that the surface of a metal wire provided with an insulating film thereon is coated with a thermal melting resin. The thickness of the thermal melting resin is, for example, approximately 1 μm. As the thermal melting resin, a thermoplastic resin or a thermosetting resin, such as a polyimide resin or an epoxy resin, containing 85 wt % of a powdered ferrite is used. This coated metal wire is densely wound to form a solenoid-type coil conductor. Next, the thermal melting resin is softened by a heat treatment at, for example, 180° C. and is then solidified by spontaneous cooling. Accordingly, the portions of the coil conductor adjacent to each other are bonded together by the thermal melting resin.

摘要： An electronic component includes an internal conductor (conductor coil) made of a metal that is embedded in a molded body. The molded body is formed by molding a ferrite resin into a fixed shape, such that at least a portion of the internal conductor is exposed on the surface of the molded body, and external electrodes, which are connected to the internal conductor, are provided in a fixed area, including the exposed portion of the internal conductor, on the surface of the molded body. The electronic component is manufactured by depositing palladium at a density of about 0.5 &mgr;g/cm2 to about 1.5 &mgr;g/cm2 in the area in which the internal conductor is not exposed on the molded body, and at a density of about 0.05 &mgr;g/cm2 to about 0.3 &mgr;g/cm2 on the internal conductor exposed on the surface of the molded body. The external electrodes are formed via a process of forming a metal film (electroless plating film) on the surface of the molded body by conducting electroless plating.

摘要： A method of manufacturing a bead inductor prevents deformation of a metal coil or dislocation of the axis position of the metal coil caused by injection pressure at the time of injecting a molten resin material from a gate. A coil is fitted onto a coil supporting pin provided on a first lower mold used for injection molding in a cavity of the mold such that the inner periphery of the coil is in close contact with the coil supporting pin. A molten, resin material is injected into the cavity. Then, the coil supporting pin and the first lower mold are removed from the molded product, and a second lower mold without a coil supporting pin is provided for replacing the first lower mold. A molten resin material is injected into the space which had been occupied by the coil supporting pin. After removing the hardened resin molded product from the mold for injection molding, the end parts of the coil are cut so as to be exposed.

摘要： A method for manufacturing a bead inductor includes the steps of forming a molded body of a resin material or a rubber material including a powdered magnetic substance, including a conductor coil defined by a wound, coated metallic wire embedded in the molded body; cutting both end portions of the molded body so as to expose end portions of the conductor coil; and attaching external terminals to the exposed end portions of the conductor coil so that the conductor coil is electrically connected to the external terminals. In order to increase the reliability of connection between the conductor coil and external terminals, both end portions of the conductor coil are immersed into a solder bath, prior to the molded body forming step, so as to include in the solder bath cutting regions of both end portions of the molded body therein such that soldered portions are formed by removing insulation coating on both end portions of the conductor coil.
