Benkovich, M G

This work evaluated a nontoxic solvent for its ability to remove solder flux as compared to trichloroethylene solvent. Isopropyl alcohol was evaluated for its cleaning efficiency for solder flux removal using a high pressure spray process (minimum spray pressure of 80 psig). Cleanliness levels were measured by the Meseran Surface Analyzer. Test samples also underwent gas chromatograph/mass spectrometer Analysis and were visually inspected under a longwave ultraviolet lamp. Detailed analyses of flux removal by the two solvents were made as related to solder flux types, solder flux diluted by 50% with isopropyl alcohol, and solder process conditions. 2 refs., 2 figs., 12 tabs.
