Organic Insulating Film with Controlled Molecule Orientation, Adhesive Film Using the Organic Insulating Film, Flexible Metal-Plated Stacked Board, Multilayer Flexible Metal-Plated Stacked Board, Coverlay Film, Tape for TAB and Base Tape for COF

摘要

A novel organic insulating film, which is continuously manufactured and has specific properties over the entire width an adhesive film, a flexible metal plated stacked board, a multiplayer flexible metal-plated stacked board, a coverlay film, a tape for TAB, a base tape for COF are provided. The continuously manufactured organic insulating film satisfies the following requirements (1)-(3) over the entire width; (1) a film MOR-c value is 1.05 or more but not more than 5.0, (2) a molecular chain main axis orientation angle is -30 to 30 degree against MD direction, and (3) a difference between the maximum and the minimum values of the film MOR-c is 1.0 or below.
