I use a Pace Desoldering station. Works on compressed air to create a
vacuume with venturi. I usually suck up all the solder then reverse the
airline to blow the rest out of the holes (rarely needed). I don't like the
idea of hot solder blowing all over the place either.

I tried using this heated air gun today. To those not familiar, here's
how it looks:

(pictured is a similar unit that I sold a long time ago).

It is a FANTASTIC tool for component removal. What it does is it blows
air at 900F, blows away all solder, removing it completely. The
components do not seem to be affected too much. The way I used it was
to blow away solder from all holes, one by one, and then I gently pull
out the component, as if it was never soldered.

It needs a compressor to operate. Which I have:

The only concern I have is a health concern of blowing away hot molten
solder that possibly contains lead, in small caplets. Seems much worse
than plain soldering. I would only use it in a garage.

HT-900B "Compressed air heater", which is supposed to blow
hot air at temperature of about 900F from a 1/8" ID or so
nozzle. It requires a compressor, which I have.


This Raychem gun is intended for use with solder sleeves (a
length of heat shrink tubing with a preformed ring of
solder in the center.) Solder sleeves are used for
applications such as attaching a jumper to the braid of a
coax cable. These guns run quite hot and I suspect would
easily damage a circuit board.

Be sure to use dry compressed air. Condensed drops of water
in the air supply can crack the heating element, which is
expensive.

I also have two Pace 2000 soldering/desoldering stations (military
surplus, recent deal), but have not yet figured out how to use
them. What model do you have? I have some questions about them...

I have a bunch of spare tips for some model of Pace desoldering
station. I'll have to see what the part numbers are.

I am pretty familiar with the Pace stations. I rebuild them now
and then, so I've been into the innards, too.

Where on earth do you find sensatemp Handles? or is that the real trick
to them? the cost isnt really in the unit its in the ST handles? I
actually have 3 different MBT units from different vintages

Great equipment i swear by it and when i need to use my field soldering
iron i swear at it in comparison.
