Abstract
A method of manufacturing a rigid-flexible printed circuit board, which including: providing a first flexible film having a first metal layer on one or both surfaces; forming a circuit pattern by patterning the first metal layer; forming a second flexible film, which has a second metal layer on one surface, on one or both surfaces of the first flexible film; forming a circuit pattern by patterning the second metal layer in a rigid domain R; providing an anti-oxidation protective layer on the second metal layer in a flexible domain F; laminating at least one circuit layer on the second flexible film; and removing the circuit layer in the flexible domain F.
