What are you using now? I don't do a lot of rework but one of my heat
guns (for shrink tubing) has some small nozzles, and it works well for
removing chips. I douse the offender liberally in liquid flux first.
Often there are other small components nearby so I'll make a little
cardboard heat shield with a window cut out of it.

I don't see the advantage of a fancy schmancy dedicated rework station.
As far as digital readouts and temperature control, I'm a bah-humbug
skeptic. You only have one choice anyway, and that's to get the thing
hot enough to melt the solder.

Separating the heater from the blower permits a bit more agility, rather
on the order of using a pencil iron versus a two-pound soldering gun.

The closed-loop temperature control is useful to allow varying the air
flow rate without also affecting the air temp.

I guess it comes down to convenience. For folks who only do onsie-twosie
surface mount reworks, it may make more sense to skip the hot air
altogether and use the ChipQuik technique http://www.chipquik.com/. The
stuff really works, but it gets pricey for large quantity use.

Stan Rubenstein are a very good source for all solder related items,
fast shipping USA

I have the Aoyue station, I wish I had bought the one with temp readout
but I just wanted to see if they were any good, no problems so far, does
its job.

I've seen that stuff before, but never tried it. I think I'll get some
though, and have it on hand for the next time I need it. Thanks for the
reminder.

Ended up getting this one. Using the one of standard single nozzles it
came with I was able to remove a 44 pin PLCC with no problems. Tried using
the same nozzle to remove a 84 pin flat pack, but this didn't work, so I
borrowed a nozzle specifically for that package from the place I work that
has a Hakko and it worked perfectly. (Good to know that Hakko nozzles are
interchangeable with this station.) I checked its output temperature with
a thermocouple and the readings were within 2c of the set temperature of
the station. No lifted pads or circuit board damage so far. Overall for
the $100 price I'm quite happy with the station, and shipping was fast as
well.
