A product such as Chip-Quik??or Fast Chip?
will drastically lower the melting point of the solder and cut down on the heat needed for removal.??
But if the part has leads which are accessible to be cut and removed individually that is my preferred method.? This is how we repaired hi-rel spacecraft PCBs.
I find that a #15 scalpel blade works well for this.
