I saw a hint about removing SMD devices some time ago.

If you do not have any tools for removing them, here is
the hint:

First, use a solder-sucker or wicking and remove any
excess solder. Then loop a #28 or so enameled wire under
the device and while heating the end, pull the wire out which
causes a gap at the end where heat is applied. Then you
can heat the other end and it will be easy to remove the

I also wondered about snapping the device in two but was
worried that the stress could lift the pad/s. So far I have not
found it necessary to remove any SMD device but now you
have another suggested method for doing it.

A little tip - for those who need it!
If you know that you are going to
replace a smd capacitor or resistor, I
find the easiest way to remove them is
to take a pair of small cutters
and cut the component in half.
Then, with a pair of tweezers, it's
easy to unsolder the two ends.
