Subject: Re: Multilayer PCB:s, HOW?
You don't do multilayers yourself.
First you do small prints yourself. Then you do
bigger ones. While the etching is trivial, the
drilling is not. And the vias take a lot of work,
namely putting a blanck wire through and solder at
both sides. From a drill/via count upwards you get
sick of doing it yourself, however low you calculate
your own time. Then you have a boardhouse do them
for you. I have a boardhouse doing a 10 x 10cm for say
50$US within 14 days. doublesided.
Then when yo spend a week or two routing a doublesided
it may come cheaper to have a multilayer done because
it may save you days of routing.
