Thanks Howard, I understand that it's excellent everywhere but the only thing with Stand-alone is how do you manage your production path if everything pass thru AOI? We produce a lot of PCB per year and as soon as a PCB break the standard path, it'

We have passed testing using this process, I would consider it on a case by case basis however. We are very careful about the quantity of the O.A. that we use. The water soluble flux is gone after cleaning unless it was/could be encapsulated or tra
