Yeah, a few. Use a magnifying glass, no matter how well you think you can see em!. My dad showed me a trick (even though I still haven't got it to work) by tying a copper 18 wire to your soldering gun. IF done correctly, the heat will transfur to the soldering gun's tip, and will make it a bit easier for you since you'll have a smaller point to be able to de solder with. I think desoldering braid might help, even though it's very little solder and it can end up de soldering everything else if you don't set it up right. In any case, you've given me a bit of precaution, knowing that I can also
up my LED's, since I'm going to re-wire my LEDs to another spot.
