Background information
Not to be confused with Hot air desoldering, Desoldering is the process of removing the solder around an object to allow you to remove it from the PCB.

Troubleshooting/tips and tricks
Fixes to any common issues that were encountered or could be easily encountered Q: The soldering surrounding the thing I want to desolder takes forever to melt
A: The board is likely absorbing the heat from the soldering iron, heating up the board as a whole is recommended to overcome the board's heat dissipation capacity.
Heat board to around 100 degrees/37.77c - 150 degrees/65.55c through the use of a board preheater.
(Not exact numbers just personal preference, experience as it heats the board enough without causing heat damage to other areas or melting other solder.)
