Hi Guys
Desoldering techniques depend on what you are trying to save: the board? the component? or both?
If all you care about saving is the component, then go ahead and use a power desoldering tool. They extract things dry - too dry - and often damage traces as a result.
If you want to save the board, you MUST EXTRACT THE PART WET.
If you want to save both the board and the part, do it wet.
There are a lot of clever devices and things out there, bu8t some are simply "too clever". Desoldering guns/stations are supposedly faster than hand methods and allow "production" removal of a lot of components. This suggests that the board is sacrificial and in my experience that is the case. For the time it takes to extract a component for the average person working on an average task, hand methods win every time. Don't spend money to be lazy and ruin a lot of boards in the process. It is the proverbial false economy that ends up costing more.
Have fun
