No,I haven't. But, I know that Dennis Hayes, during
the very early days of Hayes Microsystem's was
literally making modems on his dinning room table. He
used to tin his boards, populate them with plastic
dips and then run them through the dishwashing machine
(On cold with NO heated dry...). Then he took them out
and dryed them. Following this he put the capacitors
on and any other parts that h20 could get into. He
then sprayed them with a conformal coating.
FWIW, he told me this himself about 15 years ago, so I
assume that it is true.
Also, I know that companies and people involved in
print head and hammer bank repair use sonic cleaning
baths on a regular basis to clean grease and ink off
of pcb's and metal parts.
