ABSTRACT:
An aqueous solution for etching and activating a surface of a nonconductive substrate for subsequent chemical and, if necessary, electrochemical deposition of a metal coating containing both an activator and an etching agent. The activator is a salt or complex compound containing a metal selected from group Ib or group VIII of the periodic table. The etching agent is manganate or permanganate ion. This solution can be used in a shortened process for metallizing isolated surfaces, especially as a part of a process for making electrical connecting elements and circuit boards.
