Per IPC-A-610, secure the PWBs to standoffs using a flat washer against the board with a split washer on top between the flat washer and the screw head or nut.

Do not use toothed star washers, as they cut into the plating and laminations of the board over time and will not produce an attachment that will withstand vibration and thermal cycling.
