This should be good fodder! We wash PWAs in a water hurricane type machine, with
a hot air blower at the end of cycle. We noticed some components mainly elect.
alum. capacitors have high capacitance. After research on cap. we were
instructed to bake assemblies 20 mins @ 100c to dry them. The long term effect
of the moisture in the cap would cause electrical leakage then failure due to
corrosion.
Well this idea expanded into a question should we bake all assemblies because
many other items such as transformers, pots., coils are not hermetically sealed.
And then there is the issue with pwb material its self.

My question to the forum is, Does anyone bake after wash as a standard? All
points of view are welcome.

Thanks!
