A solid electrolytic capacitor is manufactured by screen printing a layer of valve metal powder ink in an array of pads, placing a valve metal pellet on end on each pad, and sintering the resulting assembly to produce an array of porous sintered pellets bonded through a graded density layer to said substrate. Next the assembly is electrolytically anodized to form a valve metal oxide over its surfaces. An insulating polymer may be applied to the substrate around the pellets, and the pellets are impregnated and coated with manganese dioxide. A conductive layer and counterelectrode are applied over the manganese dioxide, and the anodic oxide is removed from the reverse side of the substrate. The array may be separated into individual capacitors. |
