Default Re: Dry solder wick anyone?

I find that a quick wipe with flux pen does wonders for old wick as others have said also I have found adding a bit of fresh solder to an area that is already a bit sparse seems to get the process going and the solder sucked up.

I will admit that a bit of fresh 60/40 full-lead solder added to a joint initially made with modern ROHS lead-free solder can help loosen things up a bit before going at it with the desolder-braid.

[For legal reasons I do not advocate this approach if the reworked assembly might possibly be returned to circulation on a commercial basis]

I was thinking only of leaded solder when I suggested it as I rarely work on modern equipment.

I felt the same way until a few years ago, as I had always used a sucker. But solder suckers don't always clear out a 'through board hole' and the component lead can still be held by a stubborn bridge of solder.
As an experiment I took some coax braid, flattened it and rubbed in some flux. I was astonished at the way the braid pulled the solder out of the joint! There does seem to be a knack to it, though. I've found a good, hot iron is essential, or all you do is end up with the braid slowly cooking your fingers!
