Hi Everyone,

I am a new member to the list and I have a question on cleaning.  Thanks in
advance for any help you can provide.  It is much appreciated.

What should the value be for rinse water resistivity? The cleaner we have
is a AAT Corp Emulsonator 9700.

We use an RMA flux (both in wave solder, and in solder paste). The solvent
we use is EC7R.

Also, we currently rinse for 10 min (+ time to reach resistivity).  Does
this seem low?  We are having trouble with board cleanliness.

Once again, thanks for any help provided.

Jason
