Also, extra leads should not be cut AFTER it has been soldered. You run the risk of cracking. Probably OK for a DVD player, but not for other things.

Solder doesnt age in that form. Its sounds like you have cold joints which are bad. You joints should be smooth and shiny they hold much better than dull gray joints. Possible causes are...

Bending the legs down doesn't improve electrical conductivity but does give the joint extra mechanical strength and is done for circuit boards subjected to high vibration. But bending the leads...

Why are you replacing it with a bigger capacitor? Are you sure it's not part of some RC or timing circuit where changing the capacitor size will mess with the time constant?

I prefer the suction pen, but my boss uses wick. Try them both!

desolder and remove and then what works for me is to reheat the holes which are full of solder and push a round wooden tooth pick in the hole to open it up. With your background no problems at all.

I have used both and the suction pen works best for desoldering. Make sure not to over heat the board of other components near by. Use as little as heat as possible. You may need to scrape the...

Desolder.
I've had better luck with the suction pens than the wicks. The suction pen will be like $10-$12 and the wick cheaper, but in replacing PCB components it works *much* better. I've...
