Sorry for such a rudimentary question but is there an industry standard these days on a overall board dimension...edge-edge? I've talked to some board houses they can hold +/- 0.005" with no problems and other have problems holding +/- 0.008". Does everyone use +/- 0.010 as a general guideline unless something more critical calls out for a +/- 0.005? I've been under the impression the past few years that typical houses can do +/- 0.005 with no problems. Thanks in advance!
