Twelve-layer Second-order PCB

Criteria for a good 12-layer PCB stackup:

Viafull is Twelve-layer Second-order PCB manufacturer and supplier in China.

A. Ground planes are preferred because they are able to route signals in a microstrip configuration.

B. A 12-layer PCB based on a ground plane has low ground impedance and low noise.

C. Intermediate layers between layers serve as routing for high-speed signals. Signal layers must be stacked closely to each other even in adjacent planes.

D. You must place plane layers and signal layers in adjacent layers.

E. Large planes and power planes are tightly coupled together.

Our expert design team focuses on the following points when selecting a 12-layer stackup:

Signal layers should always be adjacent to planes

Power planes can be used as return paths for signals

Signal layers should be tightly coupled to their adjacent planes

Determine the return portion of the signal
