Unusally for this list, everyone seems to agree that
it is the way to go
but it still seems a bit black art to me. Yet we have long and
inconclusive
debates about retrobrite and the like where there are opionions on both
sides
of the fence. I'm not saying I'd like to have a big debate about this,
just
wondering if I'm missing something somewhere.
Dear Peter
I hate to "show credentials" but...
I'm an engineer with long experience in development and repair of
embbedded electronics systems, from simple household items to radar and
microwave communication systems. I've repaired boards way more complicated
(and fragile) than A4000 boards for years, and - of course - before applying
techniques unknown in fragile (and more expensive than a year's pay) boards,
I've studied the chemical and physical aspects of anything, since an error
could me cost lots and lots of money.
So, when I say something, it may even not be the more perfect method (so
it must be reproductible by people without acess to special chemicals and
tools) but **it works, because I tried and use it for years**. It isn't a
tip from a weekender.
Anyway, I can always be wrong, and I'm very happy to be confronted with
good knowledge and pratice. Anyone here, please, feel free to correct me.
But give me proof.
Very sorry to "show credentials", I don't want to be rude nor better
than anyone here in any way
Greetings from Brazil
