  • Patent number: 7195702
    Abstract: Disclosed are systems and methods of plating a tin alloy in an efficient, economical, and environmentally friendly manner. An electrochemical cell containing an anolyte compartment and a catholyte compartment separated by a selective membrane is employed. The selective membrane prevents ionic metals from migrating from the catholyte compartment to the anolyte compartment. A conduit may be employed in the electrochemical cell to permit one way flow of anolyte to the catholyte compartment thereby replenishing tin to the catholyte compartment.

  • Patent number: 6468411
    Abstract: An alkaline zinc-nickel electroplating bath comprises zinc ions, nickel ions, a primary brightener which is an N-methylpyridinium compound substituted at the 3-position of the pyridine ring with a carboxylate group or a group hydrolyzable to a carboxylate group and a secondary brightener which is an aliphatic amine. An example of a preferred brightener is N-methylpyridinium-3-carboxylate or a salt thereof. A preferred polyamine is a polyethyleimine. By the present invention, a mirror bright zinc-nickel deposit can be obtained having more than 4% by weight nickel, without blistering or decomposition of the primary brightener.

  • Patent number: 4326940
    Abstract: The invention provides an on-stream method and apparatus for analyzing of the concentrations of chemical components in a bath, especially in an electroplating bath, contained in one or more processing tanks. Moreover, the information obtained by such analysis of a single bath or of multiple baths may be efficiently employed to control such concentrations in the bath or respective baths, for example, by controlling the addition of one or more additives. The apparatus comprises a multi-steam sampling value and a computer for controlling the operation of said value. The computer also controls means for adding material to the baths in order to maintain the parameters thereof.

  • Patent number: 4134803
    Abstract: Nitrogen and sulfur compositions are described which are useful in aqueous acidic plating baths and processes for electrodepositing bright and level copper coatings. The compositions are prepared by reacting a mixture of(a) a disulfide having the formula[RR'NCS.sub.2 ].sub.2 (Formula I)wherein R and R' are each independently hydrogen, alkyl or aryl groups, and(b) a halo hydroxy sulfonic acid having the formulaX(CH.sub.2).sub.n CHOH--CH.sub.2 SO.sub.3 M (Formula II)wherein X is a halogen, n is one or two and M is hydrogen or an alkali metal, in(c) an aqueous alkaline medium.Particularly bright and level deposits are obtained when the reaction mixture used to form the composition also contains an aliphatic aldehyde containing up to three carbon atoms.
