So Bev,

LF residues really are more reactive? You seem to have done some measurements.

Thanks,

Ioan

John,
Not if they do their homework and do the proper testing to show that the
tweak in reactivity won't put them on dangerous ground.  That is why
there are tests like copper mirror, halide ion, British corrosion test,
SIR and electrochemical migration.

That's what I was thinking Brian...................8-)

With the change to lead free and the various "wetting" issues a lot of
people are using a more active flux if only to make the joints "look"
more
like 63/37 and as a result are having to use cleaning systems to remove
the
flux.

Of course the ones that do not remove the flux will find out eventually
why
they should have done!!
