Max Friedheim is the contact. We have Three system the two chamber the four
and the Six. We have clients in the disaster recovery industry that have a
Tsunami Batch Cleaner with a low pressure spray using EnviroGold 816 and a
Four Chamber PDQ steamer for a very effective trailer batch cleaning system.

Dan and Brian
We have qualified clients who clean a no clean and have since the mid 90's
(Les Hymes was one of the first). But we have found that with a rescue
cleaning
and only if you have water tolerant parts (if not those need to be removed)
that you can effectively clean a residue that was not designed to be
cleaned.
These residues do need a good saponifier, low pressure inline (not able to
do in a standard batch system), heated to 140-150 F wash and rinse with DI
water at 10 meg ohm or better, but this is not enough by itself but we
found
that if we use DI steam after wash and before rinse then we are able to
clean
under low standoff components, BGA's, and with a little help QFN and PQFN
packages. We presented this information at the IPC Midwest Expo 2007,
authored
by Eric Camden. We have successfully been rescue cleaning for the last 7
years no clean assemblies that were 6-12 months old. So it is very doable
but
standard batch cleaning with a saponifier has not proven to us or our
customers who we have help implement this type of cleaning that batch or
standard
inline cleaning is able to do the job.

"Generally speaking I have not seen good results in trying to clean off
no-clean flux. They call it "no-clean" for a reason."
Agreed!!! Even if you succeed to do the job well - it can be done with
some fluxes - it will not be very easy and may be quite costly. I have
always said, if you clean, use a flux which was designed from the start
for easy cleaning.
