Abstract (en)
[origin: WO2015059351A1] In a manufacturing method of the induction charger film according to the invention a first patterned insulation layer (15) is advantageously printed on the surface of a clean copper foil (130). In the following manufacturing stages one or more conductive (16), semi-conductive, insulating material layers or layers including graphics, are printed on the patterned insulation layer (15). When the material layers to be manufactured on the first surface of the induction charger film have been printed, the induction charger film is attached to an appropriate surface film (19). After this copper conductors (131-134) of the induction charger are patterned by etching from the second, yet untreated surface of the metal foil. After etching the conductors a ferrite film (14) is laminated underneath the primary coil (13) and the copper conductors (131-134) of the induction charger, with which ferrite film the magnetic flux created by the primary coil (13) is directed above the primary coil.
