Subj : Hakko FR-301

So I was finally able to play with my Hakko FR-301 desoldering tool.

Overall, it was a breeze to use and I'll be using this for many future projects
(like the replacement of my Tandy 1400LT battery) soon.

The solder "tip" has a hole in it. You put the tip on the solder point so that
the leg is inside the hole.  You also want the tip slightly offset so that it's
heating the leg - not the pad as much.

I usually move the tip to the side a bit to tell me if the solder has melted,
then I press the vacuum button and I now have a clean solder point.

Of course, it's not magically perfect.
Sometimes you need to add some extra solder to get a good seal on the vacuum.
And it doesn't suck the solder all the way to the other side of the board.  So
the chips do need a bit of coaxing to get off because of the residual solder on
the other side of the hole.

But I was able to desolder 3 chips (2 memory chips and a 80C85 CPU) in a very
short time with no damage to the board or the chips.


... Me, indecisive?  I don't think I am, do you?
