[time-nuts] I love the smell of tantalum in the morning

Hi Tom,
Personally, I wouldn't touch this without a hot air gun.  I don't know what your budget is.  What I consider reasonable may be an order of magnitude smaller than for you.  So, I use a generically labeled 852D+ rework combo.  It has both solder pencil and hot air gun.  There are better hot air guns for a reasonable price that have a better system for changing the nozzles.  OTOH, I've heard some complaints about this "better" system where the nozzle has fallen off.  If you've got a Pace soldering system, then you already know what to do.  =)

See C13 in the attached photo. I need to replace some blown caps on a few boards [1]. In one instance the cap got so hot it melted itself off the board. Quiet convenient, actually -- it acts like its own fuse -- but I don't think the 5071 designers had that clever feature in mind.

Having not done SMT before, how should I do it with minimal risk to the very precious PCB. Or, what equipment should I use this as a good excuse to buy?
