HI:
If you are looking into an inspection tool, depending on your microscopes, you can add on a polarized contrast light filter. this will be a direct tool that can help you out on that step. Only issue with polarized light filters, or UV lamps, is that they will identify white powderish residues only. If the flux is still "untouched" it's glare wont allow for a correct observation.
