Definitions

  • Wireless charging "wireless” charging is also referred to as wireless charging and inductive charging, although inductive charging also represents a certain type of wireless charging.
  • the shielding film comprises a plurality of layers, each layer comprising an adhesive layer and a soft magnetic film of a nanocrystalline soft magnetic iron-based alloy or an amorphous cobalt-based soft magnetic alloy disposed on the adhesive layer.
  • the adhesive layer may be a self-supporting adhesive film having an adhesive surface on one or both sides.
  • the adhesive layer can also be applied in liquid form or as a powder on the strip.
  • an adhesive sheet is disposed between adjacent layers.
  • the adhesive film can serve as a support for the soft magnetic film and be present instead of or in addition to the adhesive layer.
  • This adhesive film may be adhesive on both sides.
  • the uppermost and / or lowermost layer of the shielding film can also be covered by an adhesive film.
  • This adhesive film can serve as a protective film and / or as an adhesive surface.
  • FIG. 5 shows a schematic view of an experimental setup for the frequency-dependent quality measurement
  • FIG. 6 shows diagrams of the quality as a function of the frequency for samples with different hysteresis loops
  • Sample was first measured the quality distribution in the undivided state. Subsequently, the measurement was carried out on the respectively divided into 2, 4, 8, 16 parts sample. This corresponds to structuring of 10.2mm, 5.1mm, 2.5mm and 1.3mm with a distance of the individual parts of 0.2mm. Subsequently, the quality curve was measured again.
