Suggestions
1.For areas where the vias are dense, please avoid interconnection between the power source and the grounded area of the formation to form a division of the planar layer, thereby breaking the integrity of the planar layer,consequently increasing the area of the signal lines in the formation.
2. Power layer projection does not overlap: two layers above (including)PCB board, avoid space overlap in different power planes, mainly to reduce the interference between different power supply, especially the voltage difference between a large power , The power plane overlap problem must be avoided, considering the interval stratigraphy when it is difficult to avoid. ion of the planar layer, thereby breaking the integrity of the planar layer,consequently increasing the area of the signal lines in the formation.
3.You should ensure that the line spacing is large enough, when the line center distance is less than 3 times of the line width, you can keep 70% of the electric field does not interfere with each other. , The power plane overlap problem must be avoided, considering the interval stratigraphy when it is difficult to avoid. ion of the planar layer, thereby breaking the integrity of the planar layer,consequently increasing the area of the signal lines in the formation.
