Claim 1:
2. The circuit signal enhancement structure of a circuit board as claimed in claim 1, wherein the core layer further comprises:
at least one via;
a first inner layer circuit, disposed on the core layer upper surface and in the at least one via;
a second inner layer circuit, disposed on the core layer bottom surface and in the at least one via;
a first dielectric layer, disposed on the core layer upper surface and encapsulating the first inner layer circuit;
a second dielectric layer, disposed on the core layer bottom surface and encapsulating the second inner layer circuit;
a first circuit layer, disposed on the first dielectric layer and in at least one first blind hole of the first dielectric layer; and
a second circuit layer, disposed on the second dielectric layer and in at least one second blind hole of the second dielectric layer;
wherein the first inner layer circuit and the second inner layer circuit formed in the at least one via are electrically connected to each other;
wherein the first signal transmission circuit layer is formed by the first circuit layer and the first inner layer circuit;
wherein the second signal transmission circuit layer is formed by the second circuit layer and the second inner layer circuit.
