If you haven't soldered before:
Yes I did, a little. It wasn't a good job ;). Some soldering on (very)
big point on a SE/30 PSU. "A big pie", word to word translation from
a french sentence, "un gros p�t�"...
If you mean that it was a large copper foil area that was soldered,
then for that you will need 25W-30W, and may need to apply some
solder to the junction between the iron tip and the pad to get
better heat conduction.
You don't need to melt all the solder on a pad, as long as all of
the solder in contact with the component lead is well melted.

Thanks for that !

9) Practice a few times on something that doesn't matter!
That's the point. I need to practice, I also need to have a good
soldering iron pane. My main problem is: how removing the burned
capacitor? The last time I tried, I kill the componant I was trying to
remove ;). it was on an old PC, doesn't matter ;).
And in this, case, too, the old component is already destroyed, so you
can just cut the leads from the component and use needle-nose pliers
to remove them as you heat the joint with the soldering iron. Then
you'll usually have to open the hole in the pad with a toothpick or
other probe to insert the new component lead.
You'll find it's pretty easy with some practice.
I need ! Thanks ! Because I'm afraid about killing definitively my old
Apple.
Old printed circuit boards are easy to find, so practice should help
boost your confidence.
