Embodiment 1
[0023] Such as figure 2 As shown, a low-cost and anti-interference dual mode stack design method. In the dualstripline mode stack design, when two adjacent signal layers are simultaneously wired with high-speed signal lines, the same area of the PP layer is added at the same position core to isolate the two layers of signal interference.
[0024] The traditional 12-layer board is laminated with 6 signal layers, such as figure 1 As shown, it is designed as a 12-layer board with 8 signal layers dual mode stacks, such as figure 2 As shown, when two adjacent signal layers are simultaneously wired with high-speed signal lines, a core of the same area is added at the same position on the PP layer to isolate the signal interference of the two layers.
Embodiment 2
[0026] On the basis of embodiment 1, when the method described in this embodiment does not have a high-speed signal line in two adjacent signal layers, only the PP layer is provided to reduce the usage of the core to reduce the cost.
Embodiment 3
[0028] On the basis of Embodiment 1, when the method described in this embodiment has only one layer of high-speed signal lines on two adjacent signal layers, only the PP layer is provided, which reduces the usage of cores to reduce costs.
