I'm making a board with a Spartan-6 and DDR2 RAM. The 256 ball BGA escape can be done with only 4 layers, but the price difference between 4 and 6 layers from PCBcart isn't that high. I saw this six-layer stackup:
Milkymist One RC2 PCB Specification - Qi
Should I use this stack-up, having 3 signal layers, but better coupled ground/power planes? Or go with the standard sig/gnd/sig/sig/vcc/sig configuration?
