I've just bought new 30W soldering iron and now that I'm home, I've tried to desolder few capacitors from my MBO. Anyway, I've turned the soldering iron on, waited few minutes for it to heat up and then put the tip to the part I wanted to desolder. I was amazed - nothing happened !! Well, after let's say 30 seconds (I know, that's too long but I didn't get anything e.g. smoke or something and the capacitor didn't heat up because I was holding it on the other side) I've managed to somehow desolder it ... But now I have solder in holes, and I thought well, that's no problem.
I've used this technique:
but unfortunately, this doesn't work. I can't melt remaining solder (in the holes) by applying tip of soldering iron to the one leg of capacitor. Actually, I don't think that I can do anything with this soldering iron ...
Is there something wrong with it or with how I am using it ?
