Abstract
A flux composition is provided, comprising, as an initial component: a fluxing agent represented by formula I:wherein R1, R2, R3 and R4 are independently selected from a hydrogen, a substituted C1-80 alkyl group, an unsubstituted C1-80 alkyl group, a substituted C7-80 arylalkyl group and an unsubstituted C7-80 arylalkyl group; and wherein zero to three of R1, R2, R3 and R4 is(are) hydrogen. Also provided is a method of soldering an electrical contact using the flux composition.
