Copper slip on eletrical connectors.
Hi folks.
Is copper slip conductive?
I have a circuit board with an intermittent power loss fault. Rather than trust my very dodgy soldering, I thought a bit of copper grease may fill
any cracks in the solder.
Good idea or utter rubbish?

Rubbish, solder it or get some one who can

stick the pins of a multi meter in it and do a continuity test

You can get high silver content paint that is conductive and might work, but soldering will be much more reliable and probably easier.

nope - put the tub down.
you need to examine visually i.e. look at the joints to see if you can spot what is known as a "dry joint".
read this
any dodgy ones, you would put a small amount of solder onto the tip - the motled solder help to conduct heat - place onto joint so it mels, and add a
bit more solder to it. sometimes a bit of flux on the joint helps (plumbers flux from B&Q will work).
the joint should look like a little mountain of shiny sholder that covers the whole pad and rises maybe 1 - 2 mm up the wire.
as ^^^ say, a multimeter, if you have one, would help too.
the example of a good joint in the linky does not look all that good to me.

BTW - what circuit is it?

and much much cheaper!!!
that stuff is a last resort and is usually for restoring broken tracks - also for low current stuff.

Copaslip is not conductive it is a good insulator if you put it on thick enough. I've repaired tracks with a wire bridge rather than just rely
on the solder.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

And also for repairing heated rear windows.

I'd definately re-solder it. For the cost of one of those conductive paints you could get a nice soldering iron and some solder  And it
won't flake off as soon as you put a few mA through it....

Maybe get someone who can solder it nicely to have a go first
Also the picture above is some of the worst soldering ever!!

Yup, solder, there's no good reason to do otherwise
