Magnetic Shielding Tape for Cable and Method for Manufacturing Thereof

Abstract

A method for manufacturing a magnetic tape includes the steps of forming a thin film magnetic layer including at least one metal ribbon sheet, adhering a cover film layer to one side surface of the thin film magnetic layer through a first adhesive layer, performing flaking on the metal ribbon sheet included in the thin film magnetic layer to which the cover film layer is adhered, and adhering a conductive layer to the other side surface of the thin film magnetic layer, which includes the at least one metal ribbon sheet undergone the flaking, through a second adhesive layer, wherein the dividing includes dividing the thin film magnetic layer to provide a gap between adjacent fine pieces among the plurality of fine pieces by applying tension to the thin film magnetic layer in an extension direction of the magnetic shielding tape while the flaking is performed.

What is claimed is: 
     
         1 . A method for manufacturing a magnetic tape, comprising the steps of:
 forming a thin film magnetic layer including at least one metal ribbon sheet;   adhering a cover film layer to one side surface of the thin film magnetic layer through a first adhesive layer;   performing flaking on the metal ribbon sheet included in the thin film magnetic layer to which the cover film layer is adhered, thereby dividing the at least one metal ribbon sheet into a plurality of fine pieces; and   adhering a conductive layer to the other side surface of the thin film magnetic layer, which includes the at least one metal ribbon sheet undergone the flaking, through a second adhesive layer, wherein the dividing includes dividing the thin film magnetic layer to provide a gap between adjacent fine pieces among the plurality of fine pieces by applying tension to the thin film magnetic layer in an extension direction of the magnetic shielding tape while the flaking is performed.   
     
     
         2 . The method for manufacturing a magnetic tape of  claim 1 , further comprising the step of filling the gap with a filler containing a material which reacts with the fine pieces to form a film. 
     
     
         3 . The method for manufacturing a magnetic tape of  claim 2 , wherein a composition of the filler is different than compositions of the first and second adhesive layers. 
     
     
         4 . The method for manufacturing a magnetic tape of  claim 1 , wherein a size of the gap is adjustable according to a strength of the tension applied to the thin film magnetic layer. 
     
     
         5 . A method for manufacturing a wrapped cable, comprising the steps of:
 forming a magnetic tape using the method for manufacturing a magnetic tape of  claim 2 ;   wrapping a cable with the magnetic tape, the cable configured to transmit a signal at a first frequency, the gap having a size so that a maximum shielding frequency of the magnetic tape is substantially the first frequency.
