Cleanliness tests with the Omega Meter: A comparative study for solder flux removal
This paper reports on a dynamic conductivity test which indicates the effectiveness of solder flux removal. The Omega Meter, a device to measure residual ionic contaminants has been used to measure cleanliness as required by MIL-P-15110 and MIL-P-28809. The cleaning efficiency of seven solvents in removing three basic types of rosin solder fluxes after solder dipping has been evaluated. Results obtained indicate fairly good correlation with those obtained from radiochemical techniques and evaporative rate analysis using the Meseran Surface Analyzer. In this study, using vapor degreasing as the method of cleaning, isopropyl alcohol, trichloroethylene, and 1,1,1 trichloroethane (stabilized) respectively were the best single solvents identified in the removal of types R, RMA, and RA rosin solder fluxes. 3 refs., 6 figs., 3 tabs.
