STUDY OF WATER SOLUBLE RESIDUE FLUXES.
Abstract
The nineteen fluxes under investigation were rated according to soldering efficiencies by a modified edge dip test. The various fluxes showed marked differences in soldering efficiencies when measured on slightly tarnished copper surfaces. The soldering efficiencies varied from 55 to 91, using 100 as a perfect solder coating. The hydrazine based fluxes were somewhat more efficient than the glutamic acid hydrochloride or other amino hydrochloride. One zinc chloride flux was not quite as efficient as the hydrazine based flux, but it was somewhat more efficient then the glutamic acid hydrochloride flux. The chemical compositions of the fluxes varied widely, as shown by the spectrophotometric curves. (Author)
