  • Patent number: 5394295
    Abstract: A method of manufacturing solid state capacitors involves providing an elongate band of solid state forming metal, folding the band into a trough-like U-shaped configuration, introducing a layer of solid state metal powder into the trough, sintering the powdered metal to thereby bond the metal to the foil, partially severing the foil and sintered powder to define a multiplicity of individual units which are thereafter processed to convert the units into capacitors by sequential dielectric forming and counterelectrode depositing steps. The individual capacitors are terminated and preferably also may be tested while still interconnected by portions of the foil, following which individual capacitors are separated by cuts which register with the initial cuts which defined the individual units. The disclosure further teaches a novel solid state capacitor fabricated in accordance with the method, the capacitor exhibiting high volumetric efficiency and being particularly adapted for surface mounting.
