The invention pertains to a process for stripping conductor traces ( 2 ) of extruded or laminated flat cables ( 1 ), so-called FFCs, using laser beams ( 4 ). The invention is characterized in that a beam of a CO<SUB>2 </SUB>laser or an Nd:YAG laser ( 4 ) is used in a first step, and an excimer laser or a frequency-multiplied Nd:YAG laser is used in a second step, in that the CO<SUB>2 </SUB>laser or Nd:YAG laser is allowed to act on the extrudate ( 3 ) of FFC ( 1 ) with an intensity and duration such that an extrudate layer ( 6 ) a few microns thick still remains in the area of the conductor trace(s) ( 2 ), said layer being removed in the second step by the beam of the excimer laser or frequency-multiplied Nd:YAG laser.
