Abstract
An aqueous acidic solution for sensitizing surfaces prior to currentless deposition of copper comprises 0.01-5.0 grams per litre of precious metal ions (i.e. Os Ir Pt Pd Au or Rh) and a stoichrometric excess of Sn(ous) ions. The salts may be chlorides, bromides, fluorides, fluobarates, iodides, nitrates, sulphates or acetates, the use of chlorides being preferable. They are dissolved in an aqueous solution of HCl, HF, HBF4, HI, H2SO4 or CU3COOH which may have a concentration of 0.001N-15N. The bases treated may be Cu, Co, Ag, Au, steel, brass, sterling silver, or plastics, and the use of the solution in the manufacture of printed circuits is described when a further copper coating may be applied by electroplating or electroless plating. The use of an alkaline cleaner comprising: sodium isopropyl naphthalene sulphonate 3 g.p.l., sodium sulphate 1 g.p.l., sodium tripolyphosphate 14 g.p.l., sodium metasilicate 5 g.p.l., and tetra sodium pyrophosphate 27 g.p.l., and ammonium persulphate and cupric chloride etchant solutions is also described. Specifications 494,559, 674,630, and U.S.A. Specification 2,908,557 are referred to.
