The present invention relates to a circuit board including: a base board having a circuit region and a terminal region; a circuit pattern formed on an upper portion of the base board; and a low-melting-metal layer formed on an upper portion of the circuit pattern. A circuit board capable of reducing manufacturing time and manufacturing costs may be manufactured by omitting a photoresist process.

Circuit board

According to an embodiment of the present invention, a method for producing a duplicate of a nano-pattern texture of a surface of an object through electroforming using an imprint mold comprises selecting the object having the nano-pattern texture, disposing the selected object and pretreating a surface of the object by washing, drying and then forming a nano-thin film thereto to block transfer of impurities, metallizing a surface of the plastic mold through, e.g., vapor deposition, spraying, and wet silver mirror reaction, and performing a first electroforming of the surface of the plastic mold, and repeating to thus manufacture a plurality of metal module master molds.
