Ultra-thin and high-permeability magnetic sheet commonly used by wireless charging and near field communication, and method for manufacturing the same

摘要

A hybrid magnetic sheet of the present invention comprises: a ribbon type magnetic sheet in which a first ribbon type magnetic sheet, a bonding sheet, and a second ribbon type magnetic sheet are repetitively stacked at least one or more times; and a composite magnetic sheet in which a first composite magnetic sheet, the bonding sheet, and a second composite magnetic sheet are repetitively stacked at least one or more times, wherein a bottom level of the first ribbon type magnetic sheet is consistent with a bottom level of the first composite magnetic sheet, thereby manufacturing an ultra-thin and high permeable magnetic sheet.
