These fluxes have been specially developed for the REWORK-, HAND SOLDERINGand SELECTIVE SOLDERING – PROCESSES.
EO-RF-G003 contains the activator system of our proven water-based flux: EO-G-003; EO cat.-no. 6008.

Working instructions:

The density of the flux must be checked regularly. As the flux gradually evaporates in all application methods, the concentration increases during processing.
Pre-drying of this flux after application is always recommended, to achieve an easier transition from liquid to melting phase which makes soldering easier. Flux EO-RF-G003 has stable enough properties, which is not reduced even in the soldering process itself.

Flux EO-RF-G003 is not corrosive. Testing of the surface resistance with vapours made no difference. A big advantage is also given due to the fact, that after the soldering process little, if any at all, solid (not adhesive) residues are left. These can be easily removed with special cleansing products or alcoholic solutions
