Soldered component removal: Raychem HT-900B works GREAT!!!

Seems pretty useless for removing components from a circuit board you'd like to use again, or at least one where random solder bridges matter.

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.

I've salvaged components from junk boards for years using a propane torch and a deft touch.

(Won't blow the solder off like the hot air gun.)

I guess that you are right. It is nice for my purposes of salvaging stuff from throwaway boards.

I tried that, it was a miserable experience. I am happy that it works for you. The hot air gun is much neater.

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.

I have two problems so far. Only tried one station.

  1. The desoldering gun warms up to temp, but when I depress the pedal, something clicks inside the station (like a relay), but no pumping is evident. However, the air hose jerks a little, suggesting that some piece in the diaphragm pump is not working.
  2. The soldering gun refuses to warm up.

I will be happy to take pictures and do all kinds of things to get these issues resolved.

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.
