Claim of US Patent No. 10,561,025

1. A method of manufacturing a polymer printed circuit board comprising in a sequential order steps of:A. providing a material layer consisting of a polymer film;
B. forming circuit pattern on the material layer, wherein the circuit pattern is comprised of laser induced graphene (LIG), and the laser induced graphene is porous;
C. depositing metal nanoparticles on the LIG of the circuit pattern so that the metal nanoparticles on the LIG of the circuit pattern is used as a metal seed of a meta layer formed on the LIG of the circuit pattern;
D. pressing the circuit pattern on which the metal nanoparticles are deposited; and
E. forming the metal layer on the LIG of the circuit pattern by using the metal seed, thus producing the polymer printed circuit board.
