The flux is free of halides, does not require cleaning after the soldering process. Its use is recommended where addition of flux is carried out by the formation of foam and where automatic feed of flux is done on the basis of density measurement with a density greater than 0.800 g/cm3>. The flux contains 0.01-20.00 wt. % of carbonic acid and/or rosin as activator, 0.01-5.00 wt. % of phthalic acid as foaming agent, 0.01-3.00 wt. % of chlorinated hydrocarbon and/or 1-methyl-2-pyrrolidone as spreadability and density increasing additives and 75-99 wt. % of alkanol mixture as carrier solution. |
