摘要： The invention provides a process for producing solid electrolyte capacitors by forming a dielectric oxide film and a first cathode layer of solid conductive substance over the surface of an anode body of valve metal, and forming a second cathode layer of conductive high polymer on the first cathode layer by electrolytic oxidative polymerization. In forming the second cathode layer, the pH of the electrolyte to be used for electrolytic oxidative polymerization is maintained within a predetermined range by adding an acid or alkali to the electrolyte. Since the pH of the electrolyte remains substantially unaltered by the polymerization according to the invention, the electrolyte is repeatedly usable while permitting the resulting second cathode layers to retain the desired electric conductivity. The second cathode layer is formed by immersing in the electrolyte the anode body formed over the surface thereof with the oxide film and the first cathode layer, feeding a positive voltage with an external electrode piece in contact with the first cathode layer in the electrolyte, and shifting the feeding point at a predetermined time interval. The feeding point where the electrode piece is in contact with the first cathode layer for feeding shifts during the step of electrolytic oxidative polymerization, so that the thickness of the second cathode layer formed as centered about the feeding point is made uniform to the greatest possible extent over the entire anode body without increasing locally.
摘要翻译：本发明提供了一种通过在阀金属的阳极体的表面上形成电介质氧化物膜和固体导电物质的第一阴极层来制造固体电解质电容器的方法，并且在第一阴极上形成导电高聚物的第二阴极层层通过电解氧化聚合。在形成第二阴极层时，将用于电解氧化聚合的电解质的pH通过向电解质中加入酸或碱而保持在预定范围内。由于通过根据本发明的聚合基本上不改变电解质的电解液，所以可以重复使用电解质，同时允许得到的第二阴极层保持所需的导电性。第二阴极层是通过将氧化膜和第一阴极层在其表面上形成的阳极体浸渍在电解质中，在电解质中与外部电极片接触的第一阴极层供给正电压而形成的，以预定的时间间隔移动馈送点。在电解氧化聚合步骤期间电极片与第一阴极层接触供电位置的馈电点，使得以馈电点为中心形成的第二阴极层的厚度尽可能地均匀化在整个阳极体上，而不会局部增加。

摘要： This invention relates to solid electrolyte capacitors and is intended to decrease the contact resistance between the body of the capacitor and lead frames and the internal resistance of these components. The, invention provides a process for producing a solid electrolyte capacitor by forming a dielectric oxide film on an anode body of valve metal, forming a cathode layer of solid conductive substance on the oxide film to prepare a capacitor element, coating the cathode layer of the capacitor element with a carbon layer, coating the carbon layer with a silver paste layer to prepare a capacitor body, and bonding a lead frame to the silver paste layer of the. capacitor body with a silver adhesive. While the capacitor element coated with the carbon layer and a silver paste are being vibrated relative to each other, the capacitor element is dipped in the silver paste and withdrawn therefrom in the direction of the vibration, whereby the carbon layer is coated with the silver paste layer. The surface of the lead frame is partly or entirely formed with a high conductive layer of a material having a higher electric conductivity than the substrate of the lead frame, the high conductive layer extending from a connection to the capacitor body to a connection for an external circuit.
