Abstract: A plasma generating apparatus includes a plurality of discharge cells in which a gas is excited by a high frequency excitation signal produced at an inverter. Each of a plurality of transformers couples the excitation signal from the inverter to one of the discharge cells, thereby forming a separate resonant circuit that has a resonant frequency. A gap in the transformer core creates a stray magnetic field outside the transformer. The plurality of transformers are in close proximity to each other so that the stray magnetic field from one transformer is coupled to at least one other transformer. Coupling the stray magnetic fields between transformers results in each resonant circuit resonating at the same frequency.

Abstract: The invention relates to an electrolyte used in connection with the deposition of a gold-tin alloy on an electroplatable substrate. This solution generally includes water; stannous and/or stannic tin ions, a complexing agent to render the stannous and/or stannic tin ions soluble, complexed gold ions, and an alloy stabilizing agent that includes ethoxylated compounds with phosphate ester functional group, brightening additives based on ethoxylated phosphate esters and alkali metal fatty acids dipropionates. The brighteners may be used alone or in conjunction with each other to achieve beneficial synergistic effect. The alloy stabilizing agent is present in an amount sufficient to stabilize the composition of the gold-tin deposit over a usable current density range. The solution has a pH of between 2 and 10 and the gold ions and tin ions are present in relative amounts sufficient to provide a deposit having a gold content less than 90% by weight and a tin content greater than 10% by weight.

This solution includes an aqueous solvent in which gold is present in the form of a solution soluble cyanide complex and tin is present in the form of a solution soluble organotin complex. 2,2?-dipyridyl is present as an additive that allows the codeposition of useful gold-tin alloy compositions at current densities lower than would be possible in its absence, given the concentrations of the individual metallic components in the solution. This additive is generally used at a concentration of 0.1 to 1 grams per liter for imparting significant enhancements in providing gold-tin alloy deposits.

Abstract: The invention relates to a method for electroplating a metal deposit on electroplatable portions of composite articles that have both electroplatable and non-electroplatable portions. In this method, the invention is an improvement which comprises treating the articles prior to electroplating to provide the electroplatable portions with enhanced electroplatability. This is achieved by passing a current though a near neutral pH solution that contains a conductivity agent and a buffer to reduce or remove surface oxides and contaminants from such portions without deleteriously affecting the non-electroplatable portions of the articles. When the treated surfaces are subsequently subjected to metal plating, a uniform, smooth metal deposit is achieved.
