ABSTRACT:
A flux composition is provided, comprising, as an initial component: a fluxing agent represented by formula I:wherein R1, R2, R3and R4are independently selected from a hydrogen, a substituted C1-80alkyl group, an unsubstituted C1-80alkyl group, a substituted C7-80arylalkyl group and an unsubstituted C7-80arylalkyl group; and wherein zero to three of R1, R2, R3and R4is(are) hydrogen. Also provided is a method of soldering an electrical contact using the flux composition.
