Hi and thanks for taking the time to read this post.
The other day I was attempting to remove a capacitor from a circuit board by applying a small blob of fresh solder onto the capacitor’s pad, applying heat then sucking the old solder and new solder up with a desoldering pump.
As I was busy celebrating my success I noticed some solder had oozed over onto an adjacent pad and I tried to quickly brush it back with the soldering iron tip before it cooled, this didn’t work now I have a short circuit between the two pads. There is a streak of solder connecting the two pads together.
I applied more heat then the desoldering pump again but for some reason it is not lifting this solder streak. I then placed desoldering wire over the streak then the iron on top but this cannot shift it.
Finally I applied a lot of flux over the streak then the wire then the iron which did something but again did not list the streak.
Does anyone have any experience of this and how it may be remedied.

Many thanks in advance.

Hi. Sorry, in the second to last line it should say "lift the streak" not "list the streak"

Apologies for the typo.

Some solder braid will remove it.

Whoops, didn't read the post properly. If braid doesn't shift it try cutting between the tracks with a craft/stanley knife to break the circuit.

You are ensuring that you wet the tip of the soldering iron aren't you? This means that a small ammount (not a big blob) of fresh solder should be melted onto the tip of the soldering iron before you apply the soldering iron to the board - this acts to conduct the heat and makes a huge difference.

Are you sure there isn't a track under the solder bridge?

@YNWaN Are you telling me to apply solder onto the soldering iron before bringing it into contact with the solderwick.

@Patrick Dixon No tracks under the streak

I think the solderwick is a load of crap and is not picking up the solder.
Can anyone recommend a good wick to go for, is there any particular brand which is better than the others.

Many thanks in advane. Mark.

Yes

If there's no track under the solder, you can usually clear it just by getting the whole thing molten and wiping the iron between the pads. You definitely want to tin the iron anyway (which is what YNWaN is saying), as this will transfer the heat to the joint more effectively. Don't get too much solder on the iron though, you just want a nice shiny tip.

Many thanks for the replies. Will definetly give it a try.
