Now we need to remove each pin from the PCB. This should ONLY be done from the TOP of the PCB! Heating the joint from the bottom of the PCB will result in broken tracks on the top side if you pull the pin before it has reached the right temperature! Hold the soldering iron against each pin until it starts to wobble, then pull it gently out of the hole using a long-nosed pliers. Only hold the pin with the pliers AFTER the pin has started wobbling, otherwise the pliers will just absorb the heat and the pin will never get hot enough. If you have a programmable soldering iron, it should be set to 350 - 380°C.
