METHOD FOR MANUFACTURING FLEXIBLE PRINTED CIRCUIT BOARD

摘要

A method for manufacturing a flexible printed circuit board is provided to reduce a manufacturing cost and perform a mass production by exposing partially a connector terminal and stacking a plating layer of Au, Sn, Ag or SnPb. A method for manufacturing a flexible printed circuit board includes the steps of: allotting a pattern by patterning a copper metalized film(50); covering a photo-sensitivity material(60) on the whole pattern and exposing a pre-connector terminal(71) partially; completing the connector terminal(70) by allotting a plating layer(72) to the pre-connector terminal(71); exfoliating the photo-sensitivity material(60); conjugating a cover layer film having an opening region corresponding to the connector terminal(70); and completing the manufacture of a flexible printed circuit board by stamping the flexible circuit board centered on the pattern.
