Default Cleaning leaked electrolytic & corrosion on PCB


"DaveC" wrote in message
...
What is the best method for cleaning up leaked electrolyte? This PCB has
some
corrosion on IC leads and vias.

Is there a corrosion neutralizer that would be effective? Since the
potential
for corrosion in places that aren't accessible (deep in the vias), a
liquid
that can neutralize corrosion is called for.

Would something like DeOxit work in such an application?

This is on a Tek scope acquisition board.

Thanks.


If you can beg or borrow an ultrasonic cleaner, ordinary water with a dash
of washing up liquid will do fine,

Any crystals or ceramic resonaters should be removed before ultrasonic
cleaning.

If the construction of any components mean they trap water, a second dip
without detergent will be needed, and you may have to bake the board to dry
everything - the pre-heat phase on a SMD oven should do it.
