I guess it depend if you work for a big or a small company. My previous = job within a big organization, we had teams in place in each areas of = expertise and review process was long but very useful. With that process = in place I never had to do more than 2 spin (1st prototype, 2nd cleaning = up if needed). If you work for a small organization, there is lot of = expertise that you have to develop yourself. It is more difficult to get = your board right the first time but still feasible.

However, as we all = =3D work at companies ranging from medium tech to very high tech, this =3D seemed a good source for a non-scientific poll. For your "typical" projects, how many circuit board revisions does it = =3D take to go from the block diagram stage to full production release? I know that in the perfect world, everyone would answer "One board, my = =3D first prototype is always perfect." But we've probably all seen the =3D project where we're sent off to design a left-handed widget and =3D eventually deliver the flux capacitor that they really wanted - but only = =3D after a large number of revisions and redesigns because they couldn't = =3D figure out how to ask for what they wanted. What I'm interested in is = =3D not the extreme revision numbers, but the typical number of revisions = =3D for typical projects. And please do include all revisions for DFM, DFT, = =3D EMC/EMI related modifications. Thanks for your responses.
