The invention discloses a method for producing rigid and flexible printed circuit boards, and comprises the following steps: a produced flexible circuit board and a produced rigid circuit board bond with each other by using bonding substrate; a second through-hole is drilled on a soft-hard combination area after the flexible circuit board and the rigid circuit board bond; peelable glue is printed and solidified on the exposed flexible circuit board, and then the second through-hole is blackened which is to adhere the slight carbon dust with electric conduction function on the wall of the hole, the invention adopts the blacken way to realize the hole metalization, ; the second through-hole and the outer surface of the substrate of the rigid circuit board is coated with copper, and then circuit etching is performed on the outer surface of the substrate of the rigid circuit board; the peelable glue is ripped off, so as to perform the subsequent grinding, welding resistance, gold immersion or electro-gilding technique. The method for producing the rigid and the flexible printed circuit boards comprises the characteristic that the peelable glue is printed and solidified on the exposed flexible circuit board, thereby preventing carbon powder from being attached to a base film or a cover film of the fixable board in the blackening process, and realizing the protection for the exposed flexible circuit board.
