Just out of curiosity, what problems are you having with the coating process
that warrants plasma cleaning?

Subject: Re: [TN] Cleaning after plasma
Well, now that we have firmly established that I AM a two headed
monster
and should be shot whenever coming within 100 yards of the clean
room.....
Yes, I would have preferred not to risk the cross-contamination
issue, IF I
COULD. That plasma cleaner was the only one large enought to handle
the
assemblies in question, and I was given all of today to solve a
multimillion dollar potential problem. So going out of house was
not an
option. We already wash with a saponifier, but that does not
increase the
surface roughness of the solder mask or components. The parameters
I
selected were done so with a mild etch in mind, not the aggressive
profiles
used for decap. If you have ever been in a production crunch, you
know
that you often get put in positions were you would rather not be if
you had
your druthers.
