I've tried the Heat Gun method and it worked ok except the fumes and it's a bit slow. I've tried running a razor knife down one side but blades go dull real quick on through-hole mounted IC's. This method works ok with SMD's but the blade goes dull quickly even yet. I like the sound of NobleMetalWorks method, being able to depopulate a board without messing up the pins and possible re-use.
I decided to try this method which I had been thinking about for a few days. So I made a video and it seems to work pretty well. Just can't reuse the components. This method that I use works very well with SMD components. Fast board depopulation.
