>The fact that Marcus is making 4 layer boards is an incredible news.
Mike,
Actually 4 (or 6 for that matter) layers is not even really hard. It's
a bit more work but definately doable. Basically I do my own
multilayers because I think I'm not that good with PCB design - as
silly as this sounds. It puts me into the possition to test a board
quickly and efficiently (a four layer with say 200 holes 3.5x3.5
inches takes about 4 hours to complete) before I give it into
production. I really hate ending up with 200 boards to trash just
because I overlooked a tiny detail of elko X touching the housing
somewhere or such.
I glue the layers together with 5 minute epoxy. That's well enough for
prototyping purposes and private use. I would however not SELL such a
board to others just to be on the save side.
There are posts in the past of me about the topic where I describe the
process mostly step by step. Please bear with me if I'm too lazy to
retype all this. I'm also a bit under pressure since I leave to a two
week holiday in a couple of hours.
