Where did this come from? I hope our safety director doesn't see this or I'll have more work to do. Seriously, if is bacterial contamination, it would be lysed immediately on contact with the iron. We ask our operators to wash their hands after handl

AF, Buddy: I know someone "set you up" to ask this question, but: 1 What kind of "thermal excursions" are you interested in? Solder cycles, rework cycles, thermal shock, thermal cycling ... 2 What are you talking about boards, components, assembl
