I don't get all your doing or, for that matter, all anyone else is doing. At HP, a few years ago, we averaged 15 change overs a day on 10 lines with seldom more than 50 assemblies each lot/run. To put this in perspective, we had 1,500 active part numbers going through the shop with requirements for nearly 20 million placements/month with every type component imaginable at the time. We had only three reflow profiles, with two pastes, and they did the job but for exceptions as experiments. Doubt this answers your question but it is a trip down memory lane for me. Sure enjoyed the experience and the trip.
