摘要： PURPOSE:To realize mass production of high quality capacitor dielectric films which are designed to save resources and attain low cost by forming a thin film dielectric layer of specific ultraviolet hardening resin at least on one side of a two-sided metallic film. CONSTITUTION:An aluminum metals 2 and 3-deposited metallic film is adopted for both surfaces of a base film. After ultraviolet hardening resin is directly applied to a portion on its one side 2, ultraviolet rays are emitted under the low concentration of oxygen, thereby forming a dielectric layer 4. In a like manner, the ultraviolet hardening resin is also applied to the rear side 3 and hardened, thereby forming a dielectric layer 5. The ultraviolet hardening resin has the structure as represented in the following equation and there are two ways to use either a compound whose number of methylene group between acrylic acid groups exceeds 7 but fails to exceed 12 or a compound which has a saturated fat group ring-shaped hydrocarbon skeleton in its main chains and an ester atomic group having an acryloyl group in two side chains individually or use both the compounds.

摘要： PURPOSE:To solve various demands for smaller size and higher density of electronic components and provide a capacitor having a large capacity in small size and non-polarized and excellent high frequency characteristics accompanying the adoption of smaller-sized and lower weight-oriented equipment or the popular application of automatic insertion. CONSTITUTION:A lean solvent of polyamic acid is added to a solution which includes a polyamic acid salt on the surface of a further porous conductor so as to produce an electrocoating solution. After constant-current and voltage electrocoating is carried out at the current density of 1A/cm and less and a polyamic acid thin film is formed thereon, the polyamide film is formed on the surface of the porous conductor by heating and dehydrating the thin film of the polyamic acid. Furthermore, a conductor film, which forms a paired polarity is formed on the surface of the polyimide by laminating polypyrrole films by chemical oxide polymerization and polypyrrole films by electrolytic polymerization one after another. This construction makes it possible to provide an excellent capacitor which has a large capacity in small size and non-polarized high frequency characteristic and its manufacturing method.

摘要： PURPOSE:To increase the dielectric constant of the dielectric without decreasing the electric characteristics and to miniaturize a laminated metallized film capacitor. CONSTITUTION:A thermoplastic resin layer with a softening point of 130 deg.C or under is formed at an average film thickness of 0.05-0.20mum on top of a compound dielectric coated layer, consisting of polyphenylene oxide and a high dielectric constant inorganic powder, formed on both or one sides of a two-sided metallized film and this compound film is laminated and heat-pressed to create a metallicon electrode on both sides in the widthwise direction. As a result of this structure, even if a high dielectric constant inorganic powder is coated, there is no loss of adhesive strength during film laminating, the compound dielectric constant increases, and the size of the capacitor can be miniaturized.

摘要： PURPOSE:To improve electrical and mechanical reliability of external electrodes and lands by polishing the surface of leadout electrodes formed by metalicon at both end surfaces of capacitor element and then forming an external electrode by immersing the capacitor into melted solder bath after coating of the flux. CONSTITUTION:A leadout electrode 2 formed by metalicon at both ends of a capacitor element l is polished as the mirror surface. Next, it is coated with a water-soluble flux. After five seconds from the coating, the composition of solder of solder bath is tin : lead = 6 : 4, and capacitor is immersed for two seconds under the liquid temperature of 200 deg.C and thereafter it is taken out. Thereby, the air part is not provided at the surface of external electrode 11 and therefore the interior is not oxidized continuously. A capacitor forming external electrodes 11 is immsered into hydrocarbon halogenide such as 1-1-1 trichloroethane and fourine group solvent and is cleaned in the ultrasonic cleaner to remove water-soluble flux so that adverse effect on the other electronic parts can be prevented on the substrate after the mounting.

摘要： PURPOSE:To maintain the capacitance of a film-chip capacitor and to make it small in size by a method wherein edge faces are provided by scraping off the four corners where an electrode lead-out face and the outermost face of a protective layer are brought into contact, and a metallized contact layer is formed by flame-sprayed metal on the edge face and the electrode lead-out face on the surface formed by the outermost surface of the protective layer. CONSTITUTION:The title capacitor has the edge faces formed by shaving off the four corners where the electrode lead-out surfaces 14 and 15 of the laminated body, consisting of the protective layers 12 and 13 superposed on an element layer 11 and its upper and lower sides, and the outermost layer surfaces of protective layers 12 and 13 are brought into contact with one another, metal is flame-sprayed on the above-mentioned edge faces and the electrode lead-out surfaces 14 and 15 within the surface formed by the outermost layer surfaces of the protective films 12 and 13, and metallized contact layers 16 and 17 are formed. Accordingly, the soldering area when a film-chip capacitor is mounted can be increased remarkably, and soldering strength can be maintained sufficiently even when the thickness of the metallized contact layers 16 and 17 is reduced to the minimum in which the metallized contact layers 16 and 17 and the vapor-deposited electrode of the element layer 11 can be electrically connected. As a result, the capacitance of the film-chip capacitor can be maintained, and the film-chip capacitor can also be made small in size.
