Aqueous cleaning composition for removing flux and method of use |
| abstract |
A flux-removing, aqueous cleaning composition contains: (A) a solvent phase consisting essentially of water; and (B) a flux-removing phase containing an alkaline salt component and a surfactant formulation, the alkaline salt component containing at least one alkali metal salt, and the surfactant formulation containing at least one fluorinated, nonionic surfactant. A method of removing rosin flux residues from a substrate, preferably a substrate of an electronic circuit assembly, involves: (a) cleaning the substrate with the above-described aqueous cleaning composition for a period of time sufficient to substantially emulsify the soldering rosing flux residues to form emulsified rosin flux residues; and (b) removing the emulsified rosin flux residues from the substrate. |
