Abstract:
An apparatus for manufacturing solid tantalum electrolytic capacitors, comprising: a lower mold having an upper surface constructed and arranged to receive a length of a metallic frame having plural anode terminals and plural cathode terminals, wherein the plural anode terminals are to be joined to respective anode leads extending outwardly from plural capacitor elements, and the plural cathode terminals are coated with a thermosetting conductive adhesive onto which surfaces of the plural capacitor elements are placed;an upper mold mounted on said lower mold and having a lower surface spaced from said upper surface of said lower mold; and a heater mounted in said lower mold, such that when a pressure is applied to the plural capacitor elements, via said lower surface of said upper mold, by moving said upper mold towards said lower mold, a portion of the thermosetting conductive adhesive is squeezed from between the plural cathode terminals and the surfaces of the plural capacitor elements to respective adjacent side surfaces of the plural capacitor elements, whereby the thermosetting conductive adhesive remaining between the plural cathode terminals and the surfaces of the plural capacitor elements achieves a substantially uniform thickness, and such that when said heater is activated the plural cathode terminals and the capacitor elements become joined together by heat-curing of the thermosetting conductive adhesive.
