Planchet holder for electrodeposition of materials

A method of holding a planchet for electrodeposition of materials, comprising the steps of:

• providing a planchet having at least two faces for electrodeposition of material thereon;
• providing a container having a solution of material to be electrodeposited onto the planchet;
• providing a planchet holder to hold the planchet therein with only one face exposed for electrodeposition of the material;
• wherein the planchet holder comprises the following;
• a container cover adapted to fit over a mouth of a container, the container cover having a through-hole defined therein;
• an elongate suspension post slidable through the through-hole in the container cover, the suspension post having a connector at a distal end thereof;
• and
• a holder assembly selectively attached to the connector and extends perpendicular to the suspension post, the holder assembly having a substrate recess adapted for selectively receiving a planchet therein and an endcap secured over the substrate recess to clamp the planchet in the recess, the endcap having a port defined therein for exposing one face of the planchet to electrodeposition of a material thereon, further wherein the holder assembly includes;
• i) an elongate body;
• ii) a holder connector formed on a side of the elongate body, the holder connector mating with the connector on said suspension post to securer mount the body to the suspension post;
• and
• iii) a planchet holder extending axially from one end of the elongate body, the planchet holder having external threads, the substrate recess being formed at a distal end of the planchet holder, the endcap having internal threads mating with the holder's external threads to clamp the planchet between the endcap and the substrate recess;
• and
• suspending the planchet holder in the container at an elevated position within the solution and the container without touching sidewalls or bottom of the container.

A planchet holder for electrodeposition of materials, consisting of:

• a circular container cover having a central axis and adapted to fit over a mouth of a container, the container cover having a through-hole defined therein, wherein the through-hole is offset from the central axis;
• an elongate suspension post slidable through the through-hole in the container cover, the suspension post having a connector at a distal end thereof;
• and
• a holder assembly selectively attached to the connector and extends perpendicular to the suspension post, the holder assembly having a substrate recess adapted for selectively receiving a planchet therein so that the planchet extends in a plane parallel to the suspension post and an endcap secured over the substrate recess to clamp the planchet in the recess, the endcap having a port defined therein for exposing one face of the planchet to electrodeposition of a material thereon.
