Does the orientation of the parts on the pallet cause quality problems?

Do the positioning holes of the parts have to be placed in the lower left direction?

I am not sure that I got properly your question, but if the part is in its original package always you will get the part in the same direction (position on the tray), please check the application note AN4982

from this application note, we have

• Tray
– NXP complies with standard JEDEC tray design configuration, see Figure 18.
– Pin 1 of the devices is oriented with lead 1 toward the chamfered corner of the tray.

I hope this will help you
