Jon,
I have a hakko FR-300 desoldering gun and a knock off of a hakko station. Your right
about general use of the vacuum pump tools, but I need something I can use when it's
not practical to drag my hakko gun around and also when I work on some disk drives where I
can't easily get in to change caps but it's a bigger hassle to remove the board
(i.e. The lamp amplifier board on a persci drive)
So I'm hoping someone has some experience using both of these Soldapullt models so I
can decide which one to order.
Thanks,
Cheers,
Corey

So I think I need to upgrade to a real Soldapullt instead of the RadioShack special.
Is the slimline III model as good as the original bulky one? I don't mind the xtra
pressure to push down the plunger on the original, I'm concerned with the
effectiveness and ability to get in tight places my Hakko FR gun can't fit easily or
when it's not worth changing tips for a single different component.
Well, these things work, but if you've ever used a real desoldering station
with vacuum pump (or venturi pump) you'll realize how second-rate they are. I
routinely desolder things like 68-pin connectors with a Pace desoldering tool. The
long-acting suction with a pump makes it work 10X better. The trick, as described in the
Pace manuals, is you heat the connection for several seconds, then apply vacuum and orbit
the tip so it moves the component pin in the plated through hole. That orbiting gets ALL
the solder out of the hole.
It is amazingly better than the piston-type solder pullers.
There are also units that combine the heated tip with the piston suction unit, and work
better, as the joint is kept hot while the solder is pulled out. This is kind of in
between the two other types.
