Patent ID: 8093504

Claim:
A circuit board structure, comprising: a dielectric layer, having an upper surface and a lower surface opposite to the upper surface; a first metal layer, disposed on the upper surface of the dielectric layer and having a first circuit area, a second circuit area and a first metallic neck connecting the first circuit area and the second circuit area; a second metal layer, disposed on the lower surface of the dielectric layer and having a third circuit area, a fourth circuit area and at least a second metallic neck connecting the third circuit area and the fourth circuit area, wherein the orthogonal projections of the first metallic neck and the second metallic neck on the upper surface of the dielectric layer are not overlapped with each other; and a first ferrite element, disposed on the upper surface of the dielectric layer and overlaying at least one of the orthogonal projections of the first metallic neck and the second metallic neck on the upper surface of the dielectric layer.
