Well, typically we put rails on a lot of the boards due to the absence of fids and/or tooling holes. We do have a fixture that is somewhat universal that I could try to introduce into the next run. Unfortunately, the next run does not help my proble

I did not see any mention on the inner layer setback. We use 0.025" and have not had problems. Point loads with either a CAB or a FKN can sometimes be problematic. I would search out someone you know that has a fancort industries VDP5. This cuts th

As has been pointed out by other well experienced individuals, this is a complex question. But the simple answer is "It is your decision". Choose any goal less than 100% and strive to reach it. There are hundreds of questions to ask before an obje

We have worked out as a guide formula to help us calculate this. As we have products that range from 5 unique pars to ~300 parts it is tricky to answer clearly. we worked out an average time to change our feeders at 3 minutes (this includes removin
