ABSTRACT:
The most essential of this novel production method of planar circuit or oscillating circuits is that the most important steps for extricating the conduit tracts on at least one electrically conductive layers is performed by laser beams, whereby already the initial reference points for the plurality of circuits to be produced are practically simultaneously applied by lasers and the application of the laser technique allows, furthermore, an exact correcting of the elements of the circuit by a simple reworking and highly precise circuits are formed which are extremely economically produced.
