Of course, if the number of required component codes ( = feeders) is not very great, you might want to look into odd-form assembly machines. With them you can insert a much greater range of components than just simple radial components and you can ge

We have been asked to provide the OEE on our SMT lines. Any examples of OEE reports that I have looked seem to be from OEM or high volume production lines. Our SMT area is high mix - high changeover. We also run prototypes and start-ups through the

To do a profile at most companies, if you don't have a scrap board handy, you'll use the already-soldered board that's already been through ONE reflow cycle. You spend time attaching T/C's with the aluminum tape - after all, the prep-work is half th
