So, after the repair of a BGA, you notice white reside on a nearby connector. Correct? [Sorry we're so dense. Long day.] Tell us about: * Flux class used in repair * Flux class used in original assembly Why are you baking the assembly after repair

Shipping might be an issue for you but I have a VIP70A in storage that is roughly the same vintage but in really good shape for $5000. We pulled it from service last year to bring in a more Pb-Free capable oven. We are still running a sister oven on
