Ferrite sheet production method and ferrite sheet using same
A ferrite sheet manufacturing method according to the present invention includes (1) stacking a plurality of molded ferrite sheets to prepare a ferrite stack having gas discharge passages between adjacent molded ferrite sheets, and (2) sintering the ferrite stack. According to the present invention, productivity can be increased, and manufacturing costs can be reduced. In addition, a gas generated during combustion of a binder can be discharged using a gas discharge passage between repeatedly uneven portions disposed in one direction, thereby preventing wrinkles or waviness generated in a peripheral portion of a ferrite sheet. Furthermore, since it is possible to improve durability and reliability of an electromagnetic wave shielding material manufactured using the ferrite sheet, the ferrite sheet can be applied to various electronic products.
