이하, 본 발명의 실시를 위한 FPC용 EMI 필름 제조 방법에 대하여 자세히 설명한다.Hereinafter, a method for manufacturing an EMI film for FPC for carrying out the present invention will be described in detail.

본 발명의 FPC용 EMI 필름 제조 방법은 먼저 블랙절연층 인쇄 공정을 포함하는 도전층 가공 단계(제1차 공정)에서 시작한다. The EMI film manufacturing method for the FPC of the present invention first starts in the conductive layer processing step (the first process) including the black insulation layer printing process.

그리고, 접착제 코팅공정을 포함하는 점착단계(제2차 공정)로 연결되는 것이 바람직하다.Then, it is preferable to be connected to the adhesion step (second step) including the adhesive coating process.
