<p>Flat electrolytic capacitors for implantable medical devices (IMDs), and methods of making and using same, particularly an improved electrolytic capacitor. Methods and apparatus for securely mechanically and electrically attaching anode sheets of multi-sheet anode layers of electrolytic capacitors together in a simple manner that does not without unduly damage adjacent or exposed oxide layers are disclosed. The side-by-side stacked multiple anode sheets of a multi-sheet anode layer are joined together by precision cold welding the anode sheets together wherein deformation of the anode sheets is effected by simultaneously driving one or more set of first and second axially aligned cold weld pins into respective first and second stack sides of the stacked anode sheets to substantially equal cold weld depths, the press fixture having plate assemblies comprising a plurality of cold weld dies.</p> |
