Problem with removing solder...clearing pin.
(1/3) > >>
cepwin:
I'm building a kit and ran into an issue.   Basically I placed an LED too high  and tried first to reheat the joint and pull it down...no success and after trying that I did something that was likely stupid and decided to snip it off as I had plenty off lead and figured it would be easier to remove the solder and reseat it.   Well, I managed to clear one hole but no mater what I do I can not remove the solder and clear the other hole.
Details:
1. I'm using lead-free solder at 398c ~755f
2. I've tried the techniques I know like a solder sucker and solder wick and very little is coming up...the solder sucker seems useless.

It looks like you are not using any flux. That would be the first issue.

Then try to just use a sharpened toothpick and clear the hole using that. Melt the solder (add more solder, it will actually help), then quickly push the toothpick though the hole.

Also, the soldering on the first hole was not great to begin with. You really need flux.
Brumby:
Yes, adding more solder often helps - with solder suckers too - but the toothpick approach will be much easier when you only have the single hole to worry about.

... and extra flux is rarely a bad idea.
cepwin:
Thank you so much for your suggestions!!   Ironically I just ordered a flux pen today and if I don't have toothpics I'll pick some up.

Thanks again!!!

Instead of a toothpick, why not just use the new LED? Sure, you can only go so far before you have to line up the cathode, but...
