Jason, If IPC has no bearing on the state of the RoHS, I hope that one day some organization will. Here's a thread from another forum that hopefully makes the RoHS supporters re-think. http://www.smtinfo.net/forum/index.php?showtopic=84

If floor space is not too big a concern, don't forget about IPC9850 to really measure the true speed ratings of each PP machine.

If you are 100% inspecting, then all assemblies should be inspected to IPC-A-610 not just the first one. It sure would be nice if assemblies # 2 - 1000 were exactly the same as the first article, but they aren't.
