Abstract [en]

There is disclosed a method for applying a first metal on a substrate, which method comprises the steps a) producing polymers on the surface of said substrate, said polymers comprising carboxylic groups and adsorbed ions of at least one second metal, said ions being adsorbed at a pH above 7, b) reducing said ions to the second metal and c) depositing said first metal on the reduced ions of said second metal. The invention further comprises objects manufactured according to the method. Advantages of the present invention include improved adhesion of the metal coating, possibility to coat many difficult materials. The process is suitable for large-scale and continuous production and it will reduce the waste of metal. Circuits manufactured according to the invention display improved signal integrity.; Also there is the possibility to manufacture circuits which are built up sequentially with several layers of conductors in distinct patterns. It is also possible to manufacture of circuits with a very small line width.
