Recommendations: Solder rework station

Chris Zach
So I have been fixing these US Electricar Dolphin controllers (50kw, AC
vector motor controllers, tend to blow up because of lack of fuses on
the P12V_BAT lines) and I'm thinking about getting a new solder re-work
station.

Most of the work involves de-soldering, soldering, some SMT work and an
occasional need to remove 50 pin edge connectors and 84 pin PLCC's. My
current tools include DC soldering irons with digital temp control, 15
watt grounded irons for detail work, and an occasional use of chip-quik
when the solder removal tool just won't work.

So what would be a good step up? I hate buying junk, but at the same
time I don't need a $4,000 multi-user professional system. Any thoughts
on a good compromise? Hot air vs. solder tips? Good vacuum stations?
Good pre-heat systems?

Thanks!

Chris

We bought one of these and are very happy with it:

The iron gets a little hot to hold on to, but the hot air gun is fast
and fun to use

Put "Metcal" in as a favorate search on ebay.  I've bought brand new solder stations (Oh, yea, that one was at the Dayton Hamfest) for $50.  Very good for removing dead surface mount parts.  Also, after using this:

http://www.sparkfun.com/commerce/product_info.php?products_id=74

I can't believe how long I lived without one.  The way it came from the factory, the display shows the temperature setpoint, and you push the button to show the actual temperature.  I've re-wired both of mine so that it displays the actual temperature, and pushing the button shows the setpoint.  Much better that way.  Finally, at a hamfest, I bought a "thing" that had two temperature controllers and two hot plates with heaters in it.  I paid $20 for it, 'cause I thought the temperature controllers would come in handy.  It's _great_ for pre-heating a board on one heater (while soldering another one), then moving it to the second heater (set to the "maximum storage temperature" of the ICs), and then you hit it with the hot air to push the solder to the melting point, but very quickly (since it's already pre-heated).  Minimizes heat damage to the board this way.  I bet you could make one easily with a $20 hot plate and a $39 ebay temperature controller (or
 $1.45 atmel chip).

I've been very impressed with how you reverse engineered the controllers, and have learned how to fix them.  Keep up the good work!
