Hi Again,

In the previous Email, I did not make myself clear for everyone
to understand what I meant 'to quanify flux residue'.

In fact, I am looking for way to measure & quantify the flux
residue that left after wave soldering process, using no-clean
flux.

I understand using clean process, ionic contamination is one of
the way of measuring the residue, however, it is mainly for clean
process.

Please advise me. Thanks you.
