Mr. Boulais,
You neglect to say what flux chemistry you are using, rosins, water solubles,
low solids, etc. It may be possible to use a titration method to determine
the amount of flux present. We attempted such a titration method in the IPC
Phase 3 low solids flux project to determine the amount of low solids flux
applied to the test boards. We had limited success, but the low solids flux
was 95% isopropanol and the evaporation rate was high. Such a method might
work on the more acidic RMAs and OA fluxes. Les Hymes, The Complete
Connection, may be able to provide you more information.
