VOC-free fluxes use water as the dominant solvent. In addition to limiting the amount of volatile organic compounds (VOC) into the atmosphere, sometimes associated with global warming, VOC-free fluxes are also non-flammable. The disadvantage of VOC-free/water-based fluxes is that they require more pre-heat to drive off the water than similar alcohol-based fluxes. In addition, assemblers must be careful to ensure that the top side of the circuit board is dry, otherwise it could lead to reliability issues in the form of electromigration.

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.
