David,
Is the flux you are attempting to removed cured? I use a TEC-1631-16S Flux Remover G3 which works great for our application. I too was inquiring about USC and/or stirring with temperature.
Victor,

Dear forum,
I have some microBGAs which have a no-clean flux residue which must be
removed before they can be reballed.
I have been doing my homework regarding USC (ultrasonic cleaning) and would
like opinions on whether or not putting the microBGAs in alcohol and putting
them through a US cleaning cycle for 1 minute would damage the wirebonding.
Most of what I see regarding USC is negative, but would only a minute be
damaging to the parts or does the damage occur after more time (i.e. - 3
minutes, 5 minutes).
As always, I appreciate the feedback.
David
P.S. - Ramon, you said a 15 minute soak in alcohol would do trick, right?
