There are a few projects that I am following in this area. I am actually also looking at how to do a hot air rework station as well (yes I know that I am crazy). My end goal thought, is to make all the items that are not the soldering iron itself as small as possible. Looking at things like using computer power supplies as the power source, and then using onboard regulation/temp control. Lots of ideas, though need to get through a few other projects first.
I'm not sure what exactly you are asking about but we've got tips for the tweezers that are wide enough to desolder most dual row SMD ICs. We also have wide tips for the regular iron that you can use to desolder one side, pry it gently up and desolder the other side. For quad ICs we've got a hot air system. I think we've got enough of an assortment of tips etc to solder and desolder just about anything short of a BGA or QFN. I suspect that we've got a couple techs who would even give those a try but I prefer being albe to see the leads I'm soldering.
Most of the soldering/desoldering equipment we have is Metcal with some Hakko equipment and a few older Weller irons.
@Elizabeth.... the tweezers certainly make it easy to unsolder SMD bits. Our iron only has the tips it came with as far as I know, and they are pretty large - unsoldering the smaller Rs and Cs would be a bit clumsy. But for the big protection Diodes it works really well.
I've seen irons that can unsolder whole SMD DIP ICs - do you have any of those?
I'd recommend searching for open source soldering iron and open source soldering station to get an idea of what others have done, since you're not the first - there might even be a useful starting point.
I don't solder heavily; I have an old (>10 years) adjustable temp Weller that works fine, and we use a different model of adjustable temp Weller at work.
I'd say your list looks fine, except it's good to have a variety of tips.
We have several soldering irons with tweezers at work. They are in frequent use for unsoldering SMD diodes, resistors and capacitors. In addition, you can get different tips for the tweezers that extend their usefulness. Everything from really small tips for the small SMD resistors and capacitors to tips that are wide enough to desolder a 20 pin DIP (or in my case a 10 position DIP switch). The regular iron tips are better for soldering in most cases though.
@Aero: ...I think that we can all agree that a non-temp controlled fire starter soldering iron that you can get for $5 is really useless, but...
As a professional -- and thinking of my current projects -- I carn't help but agree... on the other hand, as a teenage lad, all I had was a non-temp controlled fire-starter soldering iron and I made it work...
I use the iron a fair bit and my workmate uses the tweezers for unsoldering and resoldering large SMD protection diodes in our two way radios (Diodes: $1.79 each; Manufacturer repair: around $ 300; so the first couple of repairs paid for the station). With both irons it is nice to use, light and the temp control seems very precise and it heats up quickly (slower for the tweezers, as you'd expect). The supplier does carry spares (for now...). AU$ 400+ (= US$ 300+) for both, so not too cheap, and beyond my means for home use, but money well spent for work.
