I must confess, never did occur to me to make use of the NC balls. I was thinking of simply pulling some balls from the footprint and simply route underneath them. This seems better, though. As long as you're not unlucky and some NC pins are actually used (as test points, for example) by the manufacturer.

Hello, Does this method really work, have you tried it on pcb? Can NC pins be used for this purpose or is it only valid for this TOSHIBA e-MMC.
