Production method of anisotropic conductive film and anisotropic conductive film produced by this method

摘要

An anisotropic conductive film is prepared by winding an insulated wire around a core member to form one roll of a winding layer, placing an insulating resin film on the obtained winding layer, and repeating the step of winding the insulated wire and the step of placing the insulating resin film to give a laminate alternately having the winding layer comprising a single row of insulated wires and an insulating resin layer made from the insulating resin film. A coating layer and insulating resin layer are melted to integrate the winding layer and the insulating resin layer. The laminate then is sliced along a plane forming an angle with the insulated wire in a desired film thickness.
