Figure 37: Six-Layer Stack-up
The figure above is an example of a six layer stack-up. Layers L1, L3, L4 and L6 are used
for signal-routing. Layers L2 and L5 are power and ground planes respectively. Microstrips
on Layers 1 and 6 reference solid ground and power planes on Layers 2 and 5 respectively.
Inner Layers 3 and 4 are asymmetric striplines that are referenced to planes on Layers 2 and
5.
