I would recommend contacting Austin American Technologies. They
manufacture board and stencil cleaners and could run some tests for
you on their equipment with various solvents. Contact Jon Phelps at
512-335-6400.
As far as solvent selection goes, I would contact the manufacturer of
your solder paste to recommend the solvent.
Make sure that the chemistry you select is compatible with the
equipment.
Good luck.

I'm working on developing a cleaning process for SMT. One of the
challenges on the product is very low part clearances. In many cases,
the devices are mounted only 1 to 3 mils from the board. Some devices
also have their bodies soldered to the substrate to provide an RF
ground. The substrates are ceramic, and the soldering process is IR
reflow.
Right now we are cleaning by hand in Axarel 2200. This is time
consuming and marginally effective. I'm looking for a faster, more
effective process. Any suggestions?
Thanks,
