Water Wash Flux
Before no-clean fluxes became the most commonly used materials in wave soldering, water wash fluxes had an extended run as the preferred material. The advantage of water wash fluxes is that they can be formulated to be very active so that they can solder virtually any assembly without a concern for reliability, since the residue will be removed after the soldering process. The disadvantage of water wash fluxes is that assemblers must have an additional piece of equipment, the water wash system, to remove the flux residue, and must deal with the effluent.
Neutral pH fluxes can generally be left on the circuit board for extended periods of time before washing, while the "low" pH fluxes generally solder somewhat better.

Not all fluxes can handle the high processing temperature required for Au/Sn solder preforms.
Soldering without flux is generally regarded as difficult if not impossible. Yet a fluxless process is routinely done with 80Au/Sn ribbon and preforms - I'll tell you how.
Au/Sn is available in all the forms you would expect from conventional solder alloys.
