A method of vacuum depositing an EMI (Electromagnetic Interference) layer using a vacuum deposition jig for a mobile phone outer case is provided. Here, when an EMI layer is fabricated in a mobile phone outer case which finally surrounds mobile phone inner circuit components in order to shield electromagnetic waves harmful for a human body and generated from a mobile phone, an EMI layer is vacuum deposited in a vacuum deposition unit, using a vacuum deposition jig which exposes only a portion where an EMI layer is to be deposited, and fully surrounds the exposed portion in the outer case. Accordingly, in comparison with an existing method, a remarkable effect of interrupting electromagnetic waves is provided and an inferiority ratio is remarkably reduced. |
