I'm not sure who generated the Chemistry Testing Guidelines that are
attached to this message, but the part about drying the sample board using
filtered compressed air could cause trouble by generating a pretty good ESD
jolt for the components on the board.

Good morning Tim,
I'm e-mailing you a data sheet for the Ionox BC cleaning chemistry for
disturbution. If you have any other questions please feel free to call me
at 603-622-2900 x111. Thank you..

Lainie -
We use an alcohol type solvent from Kyzen.  The product is called Ionox
BC.
At ACT we soak the PCB assemblies (with flux) in Ionox BC for 20-30
minutes.  After soaking for 20-30 minutes, the PCB asseblies are cleaned
in a Westek Triton high pressure in-line D.I. water cleaner.
We use this procedure to remove hard to clean white residues (both No
Clean and Water Soluable fluxes) and solder balls associated with the
No
Clean processes in general (reflow/wave).  This should also work for
cleaning baked on fluxes.
For info on Kyzen products contact Eric Bromley at Kyzen.
Regards,
Tim Tezak
