If I have components on both sides, I just do the simpler side first,
reflow it, then do the other side. No part ever felt off so far. I've
not yet been brave enough to populate both sides and do it in one
shot.... :-) Nice to hear that this would be an option also. I prefer
the two step aproach cause you then don't have to be THAT carefull with
not disturbing the already populated but not yet reflowed side.
