Abstract:
An apparatus and method for electrochemically depositing a unitary layer structure using a reactor configured to contain an electrolyte solution with an anode array containing a plurality of independently electrically controllable anodes arranged in a two-dimensional array, a cathode, an addressing circuit for receiving a signal containing anode address data and for outputting a signal causing an anode array pattern; and, a controller. in communication with the addressing circuit and the anode array, configured to electrically control each anode in the anode array to cause an electrochemical reaction at the cathode that deposits a unitary layer structure according to the anode array pattern signal.
Abstract:
Provided are: a plated material having excellent abrasion resistance, electrical conductivity, sliding performance, and low friction, and wherein a plating layer does not undergo embrittlement properly; and a method for producing the plated material. The method includes a first step of at least partially removing a reflow tin plating layer from a metallic base material having the reflow layer on at least a part thereof and a reactive layer provided at the interface between the reflow layer and the base material; a second step of at least partially subjecting a region in which the reflow tin plating layer has been removed to a nickel plating treatment; a third step of at least partially subjecting the nickel plating layer to a silver strike plating treatment; and a fourth step of at least partially subjecting a region of the silver strike plating to a silver plating treatment.
Abstract:
An apparatus for stereo-electrochemical deposition of metal layers consisting of an array of anodes, a cathode, a positioning system, a fluid handling system for an electrolytic solution, communications circuitry, control circuitry and software control. The anodes are electrically operated to promote deposition of metal layers in any combination on the cathode to fabricate a structure.
Abstract:
A copper plating solution which contains compounds with the structure —X—S—Y— where X and Y are, independently of each other, atoms selected from a group consisting of hydrogen, carbon, sulfur, nitrogen, and oxygen, and X and Y can be the same only if they are carbon atoms and aliphatic semialdehydes. By using this copper electroplating solution it is possible to form good filled vias without worsening the appearance of the plating.
Abstract:
Formation of an authentication element by deposition of a metal layer with embedded particles on a metal substrate, wherein the embedded particles are configured to convert energy from one wavelength to another. The embedded particles may be upconverters, downconverters, or phosphorescent phosphors, which can be detected and measured with analytical equipment when deposited in the metal layer. A metal substrate may include coinage.
