Perhaps I am just weird, but I rarely damage circuit boards or components
when de-soldering. I have a Hakko 808 de-soldering gun.
I raarely damage things either, nd I just use a normal soldering iron and
solder sucker. I think the trick is knowing how much force you cna apply
to the component before you risk lifting traces. If it won't come out,
dont forct it, but resolder and desolder it again.
The biggest things I have learned from de-soldering are:
Add fresh solder where you are able to, I have notices as solder ages and
oxidizes it gets to be a nightmare to melt. Also fresh Flux can help some
times.
Yes. Puttign a little new solder on helps a lot.
Also, if a pin doens;'t desolder fully the first time, it is a waste of
time to try to melt the remianing dolder and such it out. It won't coem
(there will be sufficient air flow in the clear part that the remining
solder will not be moved at all). Resodler the connection and try again.
Normally on ther second attempt, it'll come clear.
If you are using a nromal soldering iron and solder sucker, make sure the
iron is powerful enough and hot enough. You will not desodlerpars from
multi-layrer PCBs (with intenral power and ground palnes) wiht a
non-temperature-controller iron.
That isn't to say I haven't pulled components
from boards and then been
amazed at the crap that some manufacturers put into their products. I'd
rather pay 5-10$ more and have a manufacturer use quality components :(
So would I, (and I'd pay a lot more to get it), but unfortunately the
accountants that run th industry don't see it that way. They'd rather get
a little extra profit from em now, even if I'll never buy their crap again.
