PURPOSE: A method for manufacturing a double access type flexible printed circuit board is provided to reduce the number of processes and maintain a support force responding to an external force which is applied to a raw material. CONSTITUTION: A circuit formation is performed(100). A raw material is provided, cut out into a sheet status of a necessary size, and drilled(102). A sparkling carrier is adhered or hot-pressed to both surfaces of the cut raw material(104). A dry film and a liquid ink is stuck to the raw material to which a carrier is adhered(106). A pattern is formed and a substrate is developed(108) to expose and develop the raw material(108). The raw material is corroded, peeled, and dried(110). A post process is performed. A mold is manufactured. The mold is punched. A hot press/automatic forming is performed. A second press is performed. A protective process is performed. A mounting and a testing delivery is performed.
