take an horizontal toaster, your board, and voila, almost nothing remains on. It works wonderfully with modern pcbs, you can remove smds as well as through hole components.

I used common high-temperature fan for unsoldering almost anything (not just smd).
It can easily heat lots of pins together without overheating conponents for much.
Maybe a hair-dryer would also work, possibly motor would need to be slowed down, and plastic parts removed from the cavity. There is also a termal sensor that would need to be disabled. I didn't try this as I'm happy with my current fan.

i'd be real careful about how much heat a toaster gives off. you could very well be damaging the pads on your board causing them to delaminate from the FR-4.

Board facing up on the toaster, I just remove the components one by one. This method was inspired by It is kinda magic, it is as if components were never soldered. I was able to remove a whole pentium socket very easily with this method

So you can trash thm and save big amounts of space. Tiny unneded conponents can also be removed easily and trashed saving even more space. (Rich people who buy just everything usually don't understand us Scavengers)
Fan worked excellently for me, it can heat precisely as much as needed and conponents can be removed far before they reach temperature of the solder. Toaster is fine as long as you can save the board and conponents before burning out, that seems a bit trickier with toaster.

It's my pleasure Just kidding. When you have found something powerfull, you try it with everything you can to improve the process. Actually, all the boards I build today are nearly full cms. With my brand new toaster, I have all components I need.
