Method for producing printed circuit boards with rough conducting structures and at least one area with fine conducting structures

摘要

A method for producing printed circuit boards having coarse conductor structures and at least one region having fine conductor structures. The coarse conductor structures and the fine conductor structures are etched out of a metal layer in a common etching process. An etching resist patterned by means of photolithography is used in the region of the coarse conductor structures, and an etching resist patterned with the aid of a laser beam is used in the region of the fine conductor structures.
