In may not be of concern, but it is possible (as I'm sure you know) to increase individual
conductor plane thicknesses to minimize layer count. I have designed and fabricated, as have
many, MLB's with up to 10 oz copper weights.
It's not always best. It can be difficult because it requires relaminating with very resin
rich (up to 70% resin to glass ratio) prepregs (106 or very rich 1080 glass styles as
examples). The stuff fills around the thick conductors, bonds well, but is very juicey and
slips and slides a bit in the press.
