Abstract
An anode container, electroplating system, method and object so plated. A feature of the invention is that an anode container has an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof. An anode-receiving container also has a body with a plurality of sides and a lower end having a larger cross-sectional interior area than an upper end. The container may also include punched out apertures positioned to provide strength to the container and an apparatus to vibrate the container coupled to a lower end of the container.
Claims31
An electroplating system comprising:
- a solution tank filled with electroplating solution;
- an anode-receiving container having an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof, the anode-receiving container containing anode material and being within the solution tank;
- and
- a power supply electrically connected to an object to be plated and the anode-receiving container.
An anode-receiving container comprising an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof.
An anode container for electroplating comprising:
- a body having a plurality of sides and an upper and lower end, wherein the lower end has a larger cross-sectional interior area than the upper end.
An electroplating process comprising the steps of:
- supporting an object to be plated in a tank filled with electroplating solution;
- supporting plating material in the electroplating solution in a container having an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof;
- and
- supplying an electric current through the object to be plated, the electroplating solution and the container including the plating material, whereby plating material is plated onto the object.
An electroplated object plated using an electroplating process comprising the steps of:
- supporting an object to be plated in a tank filled with electroplating solution;
- supporting plating material in the electroplating solution in a container having an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof;
- and
- supplying an electric current through the object to be plated, the electroplating solution and the container including the plating material, whereby plating material is plated onto the object.
