Problems solved by technology
 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.
 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.
 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.
 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.
