The plating baths containing the organic compounds that inhibit or retard additive consumption can be employed to copper, gold, silver, palladium, platinum, cobalt, cadmium, chromium, bismuth, indium, rhodium, ruthenium, and iridium.Type: GrantFiled: October 2, 2001Date of Patent: June 28, 2005Assignee: Shipley Company, L.L.C.Inventors: Andrew J. Cobley, Mark J. Kapeckas, Erik Reddington, Wade Sonnenberg, Leon R. Barstad, Thomas Buckley

Patent number: 6852210Abstract: To provide a plating method, which enables wide industrial use of the redox system electroless plating method having excellent characteristics, and a plating bath precursor which is preferable for the plating method. The plating method comprises a process oxidizing first metal ions of a redox system of a plating bath from a lower oxidation state to a high oxidation state, and second metal ions of said redox system are reduced and deposited onto the surface of an object to be plated, wherein a process is provided in which by supplying the electrical current to the plating bath, the first metal ions are reduced from said lower oxidation state to thereby activate the plating bath. The plating bath precursor is formed stabilizing the plating bath so that reduction and deposition of the second metal ions substantially do not occur in order to improve its storing performance.Type: GrantFiled: January 7, 2002Date of Patent: February 8, 2005Assignees: Daiwa Fine Chemicals Co., Ltd., Sumitomo Electric Industries, Ltd.Inventors: Keigo Obata, Dong-Hyun Kim, Takao Takeuchi, Seiichiro Nakao, Shinji Inazawa, Ayao Kariya, Masatoshi Majima, Shigeyoshi Nakayama

Patent number: 6811674Abstract: The present invention provides a palladium plating solution comprising at least 1 to 60 g/L, in terms of the amount of palladium, of a soluble palladium salt and 0.1 to 300 g/L of a sulfamic acid or its salt, the palladium plating solution being substantially free from a brightening agent. This plating solution can be used to form, on a substrate, a palladium plating having on its surface an acicular crystal, and, thus, a plating having excellent adhesion to resin can be provided on the surface of a substrate.Type: GrantFiled: September 5, 2001Date of Patent: November 2, 2004Assignee: Matsuda Sangyo Co., Ltd.Inventor: Shinji Ueki

Publication number: 20040168927Abstract: A structure that is endowed with electric conductivity by plate-coating with a titanium nitride layer or by generation of a titanium nitride layer on a surface of a base material made of an inorganic material or an organic material, and a method of electroplating a cathode with a simple metal or an alloy, wherein the structure is used as an anode and/or a cathode. The structure is corrosion-resistant and has high electroconductivity, and thus the electroplating method using the structure allows the simplification and the cost reduction of an electroplating process.Type: ApplicationFiled: January 22, 2004Publication date: September 2, 2004Inventor: Atsushi Matsushita
