Or just clamp it upright in a vise, make sure you have good ventilation and safety glasses on, and get out a big (2000W) heatgun and blast the living tar from the solder side under the component with it, while moving the heatgun(!!!), while putting a gentle(!) pull on the component from the other side with pliers. This even has a chance to get classic PCI, DDR, or PCIeX16 slots out intact (not always, often a few stubborn pins melt out). This also has a chance of setting your donor board on fire, so prepare for the possibility. DIP chips can 95% be harvested intact this way. ...
