Yes, I've noticed relatively severe leakage problems with
water soluble and no-clean formulations. The latter are
particularly stubborn to clean (no-can-clean). Since I do a
lot of fussy analog circuits it shows up clearly.

For prototypes I have rosin core flux around, for hand made
pre production careful cleaning is called for (even spot
cleaning).

This problem is compounded by what seems to be a lack of
awareness amoung the factory reps for the solder, who seem
to only think of 'pure' digital circuits where you could
dunk the thing in tap water and it would probably still
work (for a short while).

Best regards,
