I suspect any of them can do any board that fits in a panel, and the panels they use are huge. It will cost you, though. Send e-mails for quotes and see what you get back. A lot will depend on how good the registration needs to be between layers. Back in the days when I was a CPU designer, we did backplane boards much larger than that. I once spec'ed out an impedance controlled (IOW: very thick) PCB that was 42" x 6". Yes, everybody thought I was nuts. I probably was/am, but let me tell you with an impedance controlled PCB, and passive pull-up/pull-down termination at both ends, the signal edges were text-book clean. I don't remember what it cost, but that was ages ago so it wouldn't be useful information today. For that matter, the box it went into sold for a cool $1M, and only used 6 of these boards, so it didn't matter then, either :) -dave > ? > > Thank you, Phil Taylor > > > _______________________________________________ > geda-user mailing list > geda-user@moria.seul.org > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user > _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
