摘要: A new flux composition, as well as corresponding methods for soldering electronic components to printed circuit boards, is disclosed. The new flux composition includes pimelic acid and two organic solvents. Significantly, the new flux composition leaves essentially no ionic residues at the completion of the soldering processes used to mount electronic components onto printed circuit boards.

摘要: The composition of the present invention includes a water-soluble soldering flux requiring no thermal energy to place the water-soluble flux in an active state. The water-soluble soldering flux contains (1) from about 1 percent to about 5 percent by weight, based on the weight of the water-soluble soldering flux, of an inorganic acid which, in solution, forms anions of the acid having a low propensity for forming metal complexes; (2) from about 30 percent to about 70 percent by weight, based on the total weight of the water-soluble soldering flux, of an anionic surfactant; and (3) from about 30 percent to about 70 percent by weight, based on the total weight of the water-soluble soldering flux, of a diluent. The composition of the present invention may contain a fourth component, a viscosity modifier from about 5 percent to about 40 percent by weight, based on total weight of the water-soluble soldering flux.
