I just tried this on removing a 64 pin SMD chip and it worked
fantastic. Have had Chipquik for a while but never used. Worked

This is why I recommend Chipquik.
It is a solder with a very high freezing temperature.
You mix it in with the current connection with a soldering
iron and then it stays soft for about 10 seconds giving you
time to remove the part.
I had to remove a very large transformer from a HF amp
that had 2 circuit boards joined together that was about 3cm
long. Without Chipquik, it would have been near
I'm blown away how easy it is and how much safer it is to
your board than the traditional methods of solder suckers,
vacuum stations and even solder wick.
You might want to watch their video. This is new school
and much newer technology.

The method fo removing
solder through hole components; where you can access the
per my days in medical instrumentation, is to use fine wire
cutters and cut the leads as close to the body of
The component as possible. Then remove the component. Next
take a small pair of needle nose pliers grab the lead and
heat the pad using a tip with a drop of solder on it. When
molten pull the lead out. Then reapply heat and use a solder
sucker to clear the pad and through hole. This reduces the
chances of damaging the feed through hole.
I am not a big fan of solder wick as it can often lead to
overheating the pad and damaging it.
Also if you are having trouble getting a small piece of
solder off a pad or feed through. Re-apply solder to the
whole pad and feed through and then try the solder sucker
