Metal circuit on polymer composite substrate surface and method for manufacturing the same

A method for manufacturing a metal circuit on a polymer composite substrate surface, the method comprising:

• (a) preforming a metal piece that has one or a plurality of circuit channels by metal processing;
• (b) integrating the metal piece onto a surface of a polymer composite layer, so that the surface of the polymer composite layer is deformed and bulged to have one or a plurality of bulges at the one or plurality of circuit channels correspondingly;
• and
• (c) removing a part of the metal piece, so that one or a plurality of circuit grooves is exposed to form a metal circuit layer having a patterned circuit, and the bulge is deformed and bulged at the corresponding circuit groove.
