MANUFACTURE OF SOLID STATE CAPACITORS

摘要

The present invention concerns the field of solid state capacitors and relates particularly to massed production methods for manufacturing solid state capacitors. According to one aspect of the invention there is provided a method of manufacturing multiple solid state capacitors comprising: providing a substrate layer; forming on an upper surface of the substrate layer a plurality of upstanding bodies consisting of porous sintered valve-action material; forming an insulating layer on and extending through the porosity of the bodies; forming a conducting cathode layer on the insulating layer; and forming cathode termination means on a top portion of each body; and dividing the processed substrate to form a plurality of individual capacitor bodies in each of which a portion of the substrate forms an anode terminal, a porous body is an anode body having cathode termination means provided on a top portion thereof, characterised in that the upstanding porous bodies are formed by pressing valve-action metal powder/binder mixture onto the substrate and forming the required body shapes and distribution while the mixture is in the green state and subsequently sintering the bodies.
