High-performance shielding sheet and preparation method thereof and coil module comprising the same

Abstract

The invention relates to a high-performance shielding sheet, preparation method thereof and coil module comprising the same. The high-performance shielding sheet includes at least one sheet which include: at least one shielding layer with low coercive force and low remanence formed of a soft magnetic material; and at least one adhesive layer disposed on at least one side of the shielding layer; and wherein the shielding layer includes a plurality of graphical slits, and the plurality of graphical slits divide the shielding layer into a plurality of graphical fragments; and wherein the plurality of graphical slits are filled with the adhesive layer, enabling the plurality of graphical fragments to be separated from each other and have a good insulation property. The advantages include: improving the electric charging conversion rate, increasing the charging efficiency, reducing the transmission loss, and increasing the uniformity of the electromagnetic wave transmission medium.
