Unused Pins and Center Pad (QFN-64)
What should be done with pins that are not used in the design? Is it ok to connect them to ground? On the QFN 64 footprint the pads are really small and it would help stabalize the pin footprint if I connected them to ground. The pads easily come off when I try to apply solder by hand in preperation for reflow.
What should I do with the center pad of the QFN-64? I don't think I need it for thermal purposes in my design. Currently I"m not soldering it to the pcb and it's not connected to ground.
