Abstract
Abstract Methods and apparatus are provided for high speed wire and/or strip line electroplating of metals such as tin and zinc on a metal substrate by utilizing in the anode assembly therefor a combination of the plating metal as the anode and an anode support comprised essentially of a member selected from the group consisting of tantalum, niobium, and mixtures thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
An anode structure for use in wire and strip line electroplating which comprises an anode of the metal to be electroplated selected from the group consisting of tin, zinc, and tin-zinc alloys; a support for said anode and disposed adjacent thereto, said support comprised essentially of at least one member selected from the group consisting of tantalum, niobium and mixtures thereof; and a sub-support disposed adjacent said support on the side thereof opposite said anode, said sub-support being comprised of the metal to be electroplated.
Claim 2
Dependent Claim
85 words
An anode structure for use in wire and strip line electroplating which comprises an anode of the metal to be electroplated selected from the group consisting of tin, zinc, and tin-zinc alloys; a support for said anode and disposed adjacent thereto, said support comprised essentially of at least one member selected from the group consisting of tantalum, niobium and mixtures thereof; and a sub-support disposed adjacent said support on the side thereof opposite said anode, said sub-support being comprised of the metal to be electroplated.
Claim 3
Dependent Claim
17 words
An anode structure as recited in claim 1 in which said metal to be electroplated is zinc.
Claim 4
Dependent Claim
24 words
An anode structure as recited in claim 1 in which said metal to be electroplated is tin, and the said support is essentially tantalum.
Claim 5
Dependent Claim
89 words
An anode structure for use in wire and strip line electroplating which comprises an anode of the metal to be electroplated selected from the group consisting of tin, zinc, and tin-zinc alloys; a support for said anode and disposed adjacent thereto, with at least the surface of said support comprised essentially of a member selected from the group consisting of tantalum, niobium and mixtures thereof; and a sub-support disposed adjacent said support on the side thereof opposite said anode, said sub-support being comprised of the metal to be electroplated.
Claim 6
Dependent Claim
89 words
An anode structure for use in wire and strip line electroplating which comprises an anode of the metal to be electroplated selected from the group consisting of tin, zinc, and tin-zinc alloys; a support for said anode and disposed adjacent thereto, with at least the surface of said support comprised essentially of a member selected from the group consisting of tantalum, niobium and mixtures thereof; and a sub-support disposed adjacent said support on the side thereof opposite said anode, said sub-support being comprised of the metal to be electroplated.
Claim 7
Dependent Claim
17 words
An anode structure as recited in claim 4 in which said metal to be electroplated is zinc.
Claim 8
Dependent Claim
25 words
An anode structure as recited in claim 4 in which said metal to be electroplated is tin, and the said support surface is essentially tantalum.
