Thanks for the suggestions...
I build my DAC for my stereo.. not perfect with etching boards, but I've got a nice temp controled soldering iron.
I use alcohol to clean-which will disolve resin(rosin?) too. For flux, from my military and NASA friends, I was always under the impression that they didn't allow stronger flux than RMA- and that's what I use.
Ussually get the temp on the iron right and 3-5 seconds is all it takes.
