Process for preparation of metal patterns on insulating carrier materials |
| abstract |
A process for the preparation of metal patterns on insulating carriers by photochemical means, in particular for the preparation of printed circuits, is described, in which the carrier is treated with a photo-sensitizer in the absence of wetting agents; the carrier is irradiated in a manner corresponding to the desired pattern with a radiation source; the metal seeds formed on the surface are augmented with an aqueous palladium-salt solution; a nickel layer is deposited with a nickel or nickel-cobalt bath; the metal layer is treated with an aqueous solution containing a complex-forming agent for copper-(I) ions; and a copper layer is deposited with a currentless coppering bath. |
