I always thought they used very thin PCBs and glued them together. i.e. to make a 3 layer board you make a double sided board and a single sided board and glue them together.
Anyone else know for sure?

Subject: [Homebrew_PCBs] How are multi-layer PCBs made?
Hi guys,
Last night I was thinking about 3 and 4 layer PCBS and can't seem to
figure out how they do them.
Single sided - easy, we all do that.
Double sided - easy, we do that as well with some alignment issues.
But once you get beyond that, I realize a different manufacturing
process has to be done to get the layers. How do they do it?
Chris
