Abstract: Disclosed is a circuit pattern continuous manufacturing device capable of quickly manufacturing a circuit pattern having a sufficient thickness. The circuit pattern continuous manufacturing device may include: an unwinder configured to unwind a transfer film to be horizontally unfolded; a rotary drum-type continuous electroforming part configured to form a circuit pattern having a first metal layer on the surface of a rotating cathode drum through electroforming; a continuous transfer part configured to transfer the circuit pattern, formed on the surface of the cathode drum of the rotary drum-type continuous electroforming part, onto the transfer film; a first horizontal plating path configured to additionally plate the circuit pattern, transferred onto the transfer film, with a second metal layer made of the same metal as the rotary drum-type continuous electroforming part; and a rewinder configured to rewind the transfer film.

Abstract: Disclosed is a method for manufacturing an FCCL capable of controlling flexibility and stiffness of a conductive pattern. The method for manufacturing an FCCL (Flexible Copper Clad Laminate) includes: an electroforming step of forming a conductive pattern on a mold for electroforming through electroforming; and a transfer step of transferring the conductive pattern from the mold for electroforming to the bottom of a polymer plastic film, wherein the electroforming process is performed in a plating bath equipped with a first metal, a second metal and a third metal, wherein the first metal is copper (Cu), the second metal serves to add flexibility and is one of tin (Sn), gold (Au), silver (Ag) and aluminum (Al), and the third metal serves to add stiffness and is one of nickel (Ni), cobalt (Co), chrome (Cr), iron (Fe), tungsten (W) and titanium (Ti).
