Abstract
Abstract A method for the connection of a metallic connector, the connector including a metallic member having a plurality of holes through a thickness of the member, to a metallic surface in order to provide an electrical contact between the connector and the surface, the method comprising the steps of: (a) assembling and maintaining a surface of the member and the metallic surface in close proximal contact; (b) arranging the asembly as a first electrode in an electroplating cell, the electroplating cell having a second electrode of a first metal and an electrolyte having in solution cations of the first metal; and (c) passing a pulse current through the electroplating cell in a direction at least between the second and the first electrodes such that electrodeposition of atoms of the first metal occurs on the assembly, and substantially preferentially at surfaces which define the holes in the member, such that the member and the metallic surface become connected via a layer of the electrodeposited atoms.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
A method for the connection of a metallic connector, the connector including a metallic member having a plurality of holes through a thickness of the member, to a metallic surface in order to provide an electrical contact between the connector and the surface, the method comprising the steps of:
(a) assembling and maintaining a surface of the member and the metallic surface in close proximal contact;
(b) arranging the assembly as a first electrode in an electroplating cell, the electroplating cell having a second electrode of a first metal and an electrolyte having in solution cations of the first metal; and
(c) passing a pulse current through the electroplating cell in a direction at least between the second and the first electrodes such that electrodeposition of atoms of the first metal occurs on the assembly, and substantially preferentially at surfaces which define the holes in the member, such that the member and the metallic surface become connected via a layer of the electrodeposited atoms.
Claim 2
Independent Claim
