Abstract
A method to remove solder flux residues from assembled or partially assembled electronic circuit boards employs a composition containing a nonpolar component consisting essentially of terpenes and/or terpenols, a polar component consisting essentially of a polar aprotic solvent or a mixture of polar aprotic solvents, and a surfactant. Use of this composition results in shorter cleaning times at lower temperatures with superior results.
