Make sure you take proper care of ESD while doing any customized
solution for washing (specially take care of component's sensitivity
for static charge) . I have had a very bitter experience on this.
Thanks

Hi Techies,
Typical small board applications in cleaning are not very different
from
large boards, EXCEPT something needs to be done to keep those little
guys
from flying around. Common solutions are stainless steel baskets (we
make
them here) or even a short piece of conveyor belt to cover the boards.
A
more costly, though "effortless" solution is a second conveyor belt
retrofit
to sandwich the assembly betweeen, powered and synchronized (we do
that here
too).
Hope that helps,
Ed

Technetters,
After routing stage the PCBs are washed to remove dust , fingerprints
etc .
Normally , this is done using washing machine fitted with hot water
rinse ,
soft brushes , high pressure rinse , DI rinse and dryer . As long as
the PCB
is bigger than , say , 7" by 4" , we have no problems . Probles are
with
really small boards such as 2" by 3" or even less .
What kind of washing machines are used for such small boards ?
