I decided to invest in a Hakko FR-301. It worked almost immediately. Hours of
trying before, I did it in 10 minutes!

Thank you for the feedback and the comparison of without and with it.

I am trying to remove an IC from my PDP 11/24 CPU, a DS8641. I am really
struggling
I had to desolder a fairly large number of 14/16 pin ICs from a two layer
PCB recently. I had an basic soldering iron and a spring loaded solder
sucker thing. I also had some wick but never having had good results with
this, I decided not to bother trying it this time.
I was aware of the idea
As mentioned, I find it best to cut the pins off the IC right at the IC
body and then remove them individually. Once the IC is removed, I use a
third hand to hold the board vertically, and then grab each pin with
tweezers or needle-nose pliers from one side of the board and lightly
touch the

For very-difficult de-soldering, I use a variation on the Chip-Quik
idea. I take a hunk of Cerrobend 158 fusible alloy and a file and make
a small pile of powder from it. I then pack the powder around the pins of the

PAR-38 halogen
Once the chip is out, for cleaning out the holes, I used a spring loaded
solder sucker on one side of the board, with soldering iron on the other
side.

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 have to second this comment.
I learned to solder in the early 70s building kits and again
professionally in the early 80s.

sucker and solder wick would work.
However, the most expedient and safest way in terms of

Are there any tips for removing ICs?
