Gentlemen,
I know this is completely out of topic but I know there are some dedicated
material experts among you. So please allow me to put the following question
forward:
Is there any good suggestion available on how to remove electrolytic coating
resulting from leaking electrolytic capacitors
I still think Symmetricom should get these out to Time-nuts for the cost of
shipping and handling. They could gain valuable experience from this list.
:-)
As to the cmos square wave, thats really the most reasonable issue to solve.
Low pass filter gain 10 mc xtal more gain Or lock a 10 MC sine
Hi Ulrich, yes its nasty. As far as I am aware the liquid electrolyte is
an alakali, sodium or potasium hydroxide. This retains the insulator
(aluminium oxide) on the plates by electrolytic action. When spewed on to
the PCB it is conducting and starts and electrolytic reaction that will eat
away
Do agree with the vinegar.
Essentially its a acid and opposite of the stuff so it neutralizes the
actions converting to some sort of salt that needs to be removed.
I ran into this on a hp 3586 but it was a nicad battery. These commonly leak
due to age and a really poor charging circuit. A
Ulrich,
In a lost cause I will use the Nitro-Universalverdünnung (it's aggressive to
some plastics, take care) and after them Tuner 600

Hi:
Here's a response I got from Symmetricom:
· The SA.45s actually uses cesium, not rubidium. But it is a vapor-cell
clock just like our Rb clocks.
· The Tx and Rx pins are for an RS-232 interface. Using the interface,
the clock can be programmed, and the clock’s functions can be monitored.

I suspect it's a bit early to really know what the wear out mechanisms

Well just about the very next project for me is to try the trick magnus
suggests.
Heating the bulb up on a failed unit.
Its life went down as would be typical with age.
I indeed have exactly run into the bad caps failures from the hot
environment and other cranky but typical old age issues. Like
Ulrich,
warm water, soap and brush. If not enough, try mild acids, then rinse
and dry with isopropilic acid.
Something this is simply not enough, if the corrosion reached the
inner layers of the PCB there is, IMHO, nothing to do.
Even solder resist becomes brittle and detaches from copper if

Most of them are either low leakage or low series resistance

Rubidium cells with a side arm run the side arm at a lower temperature.
Then the excess rubidium condenses in the side arm.
The vapour pressure in the cell then becomes that vapour pressure that

That is good, because when you have finished cleaning up
