Method for the formation of narrow, metal-free strips in a metal layer on plastic sheets

A method for forming narrow metal-free strips in a metal layer on a plastic sheet from which to manufacture capacitors provides moving the sheet relative to a plurality of pulsed laser beams arranged parallel to one another in a single plane parallel to the direction of translational motion of the s...

Beschreibung
Zusammenfassung:	A method for forming narrow metal-free strips in a metal layer on a plastic sheet from which to manufacture capacitors provides moving the sheet relative to a plurality of pulsed laser beams arranged parallel to one another in a single plane parallel to the direction of translational motion of the sheet to successively generate metal-free areas which are overlapped to form a narrow, completely metal-free strip.
