Method of Regenerating Nickel Sulfamate Plating Baths U.S. Patent 5,478,461. Dec. 26, 1995 6. Sala et al, assignors to Framafome, Courbevoie, France

A method of regenerating a passivated nickel plating electrolytic bath containing nickel sulfamate, prior to nickel plating, comprising subjecting the bath to a reduction treatment until the bath is unable to be used for electrolytic nickel plating; and slowly oxidizing the bath and stopping the

fective amount of an evaporation inhibiting agent, which is at least partially insoluble in the composition and forms a film upon exposure to air.

Apparatus to Control Zinc Phosphate Solution

A process for coating at least one surface of a polyimide sheet with copper in the absence of an adhesive comprising contacting with a one-phase solution comprising a diamine at a temperature sufficient to render at least one surface uniformly and substantially completely hydrophilized; treating with a catalyst to render the surface receptive to the electroless deposition of nickel or cobalt; depositing nickel or cobalt by electroless deposition; and depositing copper by electrolytic deposition to form at least one exposed copper coating on the polyimide sheet.

An activity control apparatus for controlling zinc phosphate treatment solution in a prescribed range, comprising a treatment vessel containing zinc phosphate treatment solution comprising complex hydrofluoric acid as an activity material; and means for adding simple fluoride solution to thereby control the activity of the zinc phosphate treatment solution.
