Zusammenfassung:	An electro-chemical deposition apparatus and method of fabricating the same is generally provided. In one embodiment, the apparatus includes an annular conductive body adapted to support a substrate and at least one electrical contact pin adapted to electrically bias the substrate. The electrical contact pin has a portion that is brazed into a pin receiving pocket formed in the conductive body. A method of fabricating a contact ring utilized for substrate plating includes the steps of inserting a portion of at least one contact pin in a pin receiving pocket formed in an annular conductive body to form an assembly and brazing the contact pin to the conductive body in a manner that excludes gases between the inserted portion of the contact pin and the pin receiving pocket.
