I (we) use ONLY rosin flux for all work. Imho rosin has passed all
time-tests. Do you picture those dead bugs preserved perfectly for ~2
million years in a drop of amber ? That's a test that is good enough for
me ;-) Ditto the early electrostatic experiments which almost always used
amber (dielectric !). Rosin is in fact the base material for amber. Just
don't clean the boards and leave for 100-500 years to set ;-)
