Abstract: Chromium or chromium alloys can be plated from an aqueous solution of a chromium (III) thiocyanate complex having at least one ligand other than thiocyanate or water in the inner co-ordination sphere. One complex is a chromium (III) chlorothiocyanate complex which can be prepared by equilibrating chromium chloride with sodium thiocyanate.

Abstract: Solder is applied to a circuit board 7 by dipping the board into a bath 1 of molten solder 3, the molten solder having a layer of oil 5 on top. The solder is dipped into the bath by rotating it along a path that is substantially coplanar with the circuit board. This is achieved by supporting the board on a carrier 9 which in turn is attached to a motor shaft 11.

Abstract: TRIVALENT CHROMIUM ELECTROPLATING SOLUTION AND BATH A chromium electroplating solution in which the source of chromium is an aqueous solution of chromium (III) complexes. The complexes are selected from a solution of chromium (III) and at least one of aspartic acid or an organic compound having a -C=S group or a -C-S- group. A supporting electrolyte is chloride free and comprises a mixture of sodium and potassium sulphates in a concentration sufficient to provide electrical conductivity for the plating process. The concentration of sodium sulphate is in the range of about 0.1 to 1 Molar and the concentration of potassium sulphate is about 1 Molar.

Abstract: Method and Composition for Electroplating Chromium and its Alloys and the Method of Manufacture of the Composition A plating solution, the making thereof and the use for chromium plating is disclosed. The solution is an equilibrated essentially aqueous solution of a hexavalent thiocyanatochromium III complex wherein the ratio of the total chromium III to the total thiocyanate is about 1:6. A preferred and improved method of making the solution from a hexathiocyanatochromium salt is also disclosed.
