Abstract (en)
[origin: EP0166327A2] 1. Process for the manufacture of printed circuits by the wet-chemical metallizing of baseboards with the aid of organometallic activators, characterized in that a) the baseboards are activated, without prior etching, with a solution of 0.01-10 g/l of a complex compound of Pd, Au, Pt or Ag with a conjugated diene, alpha, beta unsaturated ketone, 4-cyclohexene-1,2-dicarboxylic anhydride or 4-cyclohexene-1,2-dicarboxylic imide, b) an electronically conductive metal coating with a layer thickness of 0.05-10 mu m and a stability to separation of at least 25 N/25 mm according to DIN 53 494 is applied to the boards activated in this way, by a wet chemical-electroless method or a combined wet chemical-electroless/electroplating method, and c) the baseboards metallized in this way, i. e. the so-called semi-finished products, are further processed in the customary manner to produce printed circuits.
