What is the best way to incorporate this kind of chip onto my pcb design? I would like to use a socket for incase it gets busted. Where can I find footprints for this type of sockets (64pin)

If the QFN is part of a large design board or if it is likely to need replacement
make an adapter PCB otherwise solder it onto your main PCB.

Make sure to use the recommended footprint. If the part has a thermal pad the usuall
recomendation is mutliple small PCB pads with vias. Solder wicking in the vias
really pulls the chip tight to the board.

The boards I did were soldered on a $20 hot plate which worked well.
