METHOD FOR MANUFACTURING MULTILAYER FLEXIBLE CIRCUIT BOARD

摘要

PURPOSE: A method for manufacturing a multilayer flexible circuit board is provided to easily laminate layers on the board by accurately positioning the board of the layers. CONSTITUTION: In the method for manufacturing the multilayer flexible circuit board, an exposure mask is prepared, in which a plurality of pattern holes corresponding to the board of the layers of the multilayer flexible circuit board are arranged in a direction perpendicular to a conveying direction(P) of a base(2). A plurality of wiring patterns(3) corresponding to the board of the layer of the multilayer flexible circuit board is then formed on the same base(2) by using the exposure mask.
