i had some time ago to solder similar small things. we had used some kind of oven to heat the whole circuitboard. the solder wasn't some kind of wire like yours, it was metalldust with some flux i think...

You could just get a cheap tip and file/grind it down. Or, you could heat up a piece of wire with a torch and use it.

Honestly Stop drinking caffeine containing beverages for a few days most of your shakes will go away, I know to most this will sound crazy but it works, you might be grouchy but you can solder....

Is that solder thin enough to use for that chip? Just the solder wire looks wide enough to bridge two pads, so when it's melted into a blob... I thought for jobs this small, you were meant to use soldering paste and either very quickly swipe it with an iron or hot air pencil, or use a reflow oven. You'd have to be the ultimate soldering ninja to do all those pads with a regular iron and not smoke the chip, surely? It might be possible to flux the traces on the board, tin them individually with solder (and remove bridges), flux the chip, put it on the board then swipe it with an iron tip but that's a pretty hacky solution.

Sparkfun.com has some really good tutorials for surface mount soldering.

Go to the Tutorial Page, and scroll down to the section Surface Mount Soldering Tutorials.

Good luck. That one looks like a bear.

I guess that could work, and I see why you need a fine iron tip (and a steady hand.) That's a challenge, for sure. Good luck.

good luck with that, 2 potential problems 1) Wire is kinda springy so it's going to be hard to keep it steady on the bad 2) careful of solder bridges and overheating. I wish you goodluck soldering those.

Well there is an 'ible about making such things... Cheap maplins irons have a nice fine tip but they're 25W meaning you'd not be able to do the job, the trick is to have a high heat and a quick solder to stop these from getting burnt...

I can't find it now, I'll do it though, it wouldn't do for this project because it's only 25W though...
