  • Method of forming termination on chip components
    Patent number: 6541302
    Abstract: A method for forming terminations on the opposite ends of a chip component includes placing a chip component in a cavity with one end of the chip component exposed. Termination conductive material is then deposited on the exposed end of the chip component and the component is removed from the cavity and reversed. Termination material is then deposited on the other exposed end. One modification of the invention includes extending the chip components completely through holes in a plate so that the opposite ends of the chip component are exposed. The termination material is then placed on the opposite ends of the chip component.

  • Tantalum chip capacitor
    Patent number: 6380577
    Abstract: The tantalum chip capacitor of the present invention includes a anode terminal which is substantially flat. The tantalum wire which extends from the tantalum pellet through the insulating material terminates substantially flush with the insulating material, allowing the termination materials to be applied over a substantially flat surface. The tantalum chip capacitors of the present invention are created by methods which include the step of grinding the anode end of the capacitor so that the tantalum wire is flush with the insulating material. Conductive materials can then be applied to the anode end of the capacitor creating a substantially flat anode terminal.
