I bought a Hakko FR301-03 in mid 2020 and, while I haven't used it for a lot, I
can attest it has worked very well for what I have done. I have used it to
replace the RIFA caps on the boards of 3 H7864 power supplies and the pico
fuses on several KDJ11-B 11/73/83 CPU boards. In each case the solder was
removed quickly and the parts literally dropped off the boards. I have also
used it to rework some badly soldered (by me) sockets on a QBone card I was
assembling. While it was relatively expensive (to me) it has been worth the
cost.

I do have some diagonal cutters, but although small they seem to be still too
bulky to reach the pins. I will have to try to find some finer ones. These seem
to look OK:

Also, I have seen the recommendations regarding a Hakko 808. It looks like the
modern successor is the FR301

may be better about this is the wider choice of nozzles.

Subject: Re: Advice on Desoldering an IC
Cut the pins with a very sharp set of dykes then remove them one at a time.
Then use flux and detailer braid to remove the solder

I am trying to remove an IC from my PDP 11/24 CPU, a DS8641. I am really
struggling to desolder it. I am using the technique of applying fresh solder
and then removing it. But after multiple cycles of this I think I am
starting to damage the PCB.
I am using a fairly cheap desoldering station (this one
https://cpc.farnell.com/duratool/d00672/desoldering-station-uk-eu-plug/dp/SD
01384?st=duratool%20desoldering). Its spec in terms of vacuum pressure is
equivalent to that of the professional Hakko ones though. I am also trying a
hand desoldering pump. None of these are able to clear many of the holes of
solder, although some are doing better than others. Nevertheless, the IC
remains stubbornly unmoving.
Are there any tips for removing ICs?
Thanks
Rob
