High current density meaning

For the top and bottom layers of printed circuit boards, the maximum current density can be as high as 35 A⋅mm −2 with a copper thickness of 35 μm. Inner layers cannot dissipate as much heat as outer layers; designers of circuit boards avoid putting high-current traces on inner layers.
