Printed circuit board

Abstract

A printed circuit board print (PCB) having an insulation layer; an intaglio pattern formed by depressing a part of the insulation layer corresponding to a location where a circuit pattern is to be formed; and conductive ink forming the circuit pattern by filling the intaglio pattern. A method of manufacturing the PCB includes providing an imprinting stamper with a relievo pattern formed in correspondence with a circuit pattern data using the circuit pattern data, forming an intaglio pattern corresponding to the relievo pattern by pressing the imprinting stamper on an insulation layer, and forming a circuit pattern by printing conductive ink in the intaglio pattern by an ink-jet method using the circuit pattern data, allows the forming of a circuit pattern to a required thickness by injecting conductive ink in a groove processed by the imprint method, and prevents the spreading of ink and the distortion of the pattern shape in the curing process for conductive ink containing metal. Also, the circuit pattern CAD data used in the manufacturing of an imprinting stamper can be utilized again in the ink-jet printing process.

1 . A printed circuit board comprising:
 an insulation layer;   an intaglio pattern formed by depressing a part of the insulation layer corresponding to a location where a circuit pattern is to be formed; and   conductive ink forming the circuit pattern by filling the intaglio pattern.   
   
   
       2 . The printed circuit board of  claim 1 , wherein the intaglio pattern is formed by pressing an imprinting stamper on the insulation layer, the imprinting stamper having a relievo pattern formed in correspondence with the circuit pattern. 
   
   
       3 . The printed circuit board of  claim 1 , wherein the conductive ink is printed by an ink-jet method in the intaglio pattern.
