Try reading what I wrote. If you reverse bias an existing capacitor -
apply a couple of volts of postive bias to the negative terminal and
ground the positive terminal - you should progressively convert some
of the insulating oxide layer back to aluminium. Measure the current
that is going through the capacitor while you are doing this and keep
it fairly low - as when you "reform" an electrolytic capacitor (which
doing exactly the opposite)

http://www.vcomp.co.uk/tech_tips/ref...eform_caps.htm

- how low depends on the capacitance of the capacitor you are fooling
around with.

A 33k resistor is probably as good as any to start with - if you screw
up the voltage until you've got say 30uA running through the capacitor
then leave it for a few minutes (watching to see whether the current
starts creeping up) then measure the capacitance of the capacitor
again to see if you've made any difference. Keep on extending the time
until you get bored, or do see a difference. If nothing much seems to
be happening, push up the voltage to get more current flowing.

I've never tried this - though I have reformed old electrolytic
capacitors - so I can't guarantee anything.

If you tried Pieter's approach you'd have a good chance of getting the
capacitor to spit out gobs of electrolyte, which creates an unpleasant
mess.

Have you not been paying attention to what is happening here recently?

Michael Terrell was *not* the source!

Ouch. I had noticed that someone was producing posts that purported to
come from him, but they were fairly obviously false. I should have
paid more attention to the signature.

I plead jet-lag. I got off the plane from Australia on Tuesday, so
I've been thinking that I ought to be okay by now, but I'm obviously
not thinking straight yet.

If you weren't quite the ill-informed idiot that you are, you'd know
that the dielectric in an electrolytic capacitor is formed by the
electrolytic oxidation of the surface of the aluminium foil the forms
the plates of the capacitor.

If you reverse bias the capacitor you can reverse this process, making
the dielectric thinner ( and more likely to break down). Sadly, the
reverse process is unlikely to thin the oxide layer to exactly the
same extent at every point, so you run the risk of lowering the
breakdown voltage faster than you increase the capacitance.

As cheap goes, this about a poor and investment of your time as you
could make - short of slandering me in this user group which however
does seem to give you some kind of demented satisfaction - but do try
it. You won't enjoy the process at all, but does that worry me?

If the capacitor is large enough the vent is restrained and the supplied
current is adequate you get a nice mushroom cloud.

No, he didn't produce that fake.

Bill, you're an idiot. Mike Terrell didn't post that.

Never mind.

I believe the reforming process is intended to restore voltage
handling capability of the part. It won't alter the part's
capacitance.

The process is also covered by the old MIL-HDBK-1131.
