Claim of US Patent No. 9,480,155

1. An electronic device, comprising:
a housing having a base and having a lid that rotates relative to the base; and
a flexible printed circuit having a metal layer that is patterned to form metal traces including signal traces and ground
traces, wherein the metal layer has first and second metal coating layers on opposing upper and lower surfaces of a metal
core layer, wherein the first metal coating layer coats all of the upper surface of the metal core layer, wherein the second
metal coating layer coats all of the lower surfaces of the metal core layer, and wherein the first and second metal coating
layers have a higher Young's modulus than the metal core layer and prevent cracking in the metal core layer.
