there are various impedance line in both the internal and external layer , and various impedance control requirment.

accurate impedance control, the impedance tolerance is 100 ohm+/-5%,50 ohm+/-5 ohm

the integration of the board design is very high, thick diameter ratio of more than 10:1, heavy copper plating is difficult
