How to desolder an element from a PCB?
Whenever you have to desolder something the first question you need to ask yourself is: do I need the component intact?

Because if you removing damaged component then often the easiest way is to separate its pins first. For most but the smallest SMD components this can be done with wire cutter. The plastic connector shroud can be broken or melted away etc. Once you've done that removing pins one-by-one becomes trivial.

If you do need the component, see if you can distribute heat to all pins simultaneously. For 2-5 pins this usually can be done by adding solder to the pads, making a blob of molten solder. For more pins you can cut a piece of heavy gauge copper wire and put it along the pads, then cover everything in solder and keep heating until all pins got loose. Here is very good video demonstrating this technique.

Pump and/or wick can be used afterwards to clean the pads.

In either case having an iron suitable for the job is most important. Big chisel or screwdriver type tips work best for this.
