摘要 |
A FPCB includes a signal layer, a ground layer, and a dielectric layer lying between the signal layer and the ground layer. At least one high speed signal transmission line is formed on the signal layer. The ground layer has a copper-removed area corresponding to the transmission line. Two ground lines are symmetrically disposed at two opposite sides of the signal transmission line and substantially parallel to the signal transmission line, each ground line and the signal transmission line is spaced at a first predetermined distance. Each ground line and the signal transmission line are spaced at a first predetermined distance. |
