Yep.

Make sure you're using the correct solder?, 60 tin and 40 lead for
repair work.
Use some extra solder paste to clean the area..
It's possible you have Lead Free Solder, that's hard to work with..


It is lead free, but that doesn't matter when I'm trying to desolder the OEM
joint. I think it's just not hot enough but I'm surprised - I thought 30W
would be plenty.

You need flux. I'm surprised my friend Arfa didn't mention that in his
otherwise thorough treatise.
