Title: SOLVENT SYSTEMS FOR USE IN CLEANING ELECTRONIC AND OTHER COMPONENTS
Abstract:
A method for cleaning a precision component by immersing the component in a heated solvating agent disposed in a pre-clean module tank to thereby remove an adherent contaminant; treating the component with a rinsing solvent to remove any remaining contaminants and residual solvating agent in a separate rinse degreaser whereby contaminants removed from the component collect in the rinse degreaser; and removing contaminated rinsing solvent from the rinse degreaser to a micro-still to separate the contaminants from the rinsing solvent and direct the rinsing solvent to the rinse degreaser. The solvent system exhibits complete miscibility of the cleaning solvent with the rinse solvent to allow for (a) complete rinsing of the cleaning solvent by the rinse solvent, and (b) the complete separation of the cleaning solvent and the rinse solvent by simple distillation.
