Abstract
Abstract The method is used to produce transmission lines for high-frequency and extremely high-frequency circuits in which crosstalk is prevented. A known method embodies electrochemical, photographic and mechanical processing steps. The method according to the invention is based on the idea of avoiding mechanical processing steps. This is achieved by using a photographically structurable film and the repeated sequence of photographic processes, and of electrodeposition and electroless deposition of copper. <IMAGE>
