Automatic laser die-cutting process for magnetic isolation sheets

The magnetic isolation sheet is a magnetic sheet auxiliary material for the coils at both ends of the wireless charger. It is a soft magnetic material sintered at a constant high temperature, with high magnetic permeability and low magnetic loss factor. It uses the electron scattering caused by the thermal motion of the lattice electric field of the functional component and the interaction between electrons to absorb the electromagnetic wave energy and convert it into heat energy, thereby achieving the purpose of attenuating the electromagnetic wave.
