Pin 1 indicator
The dot, notch, bevel, chamfer or dimple on a package that identifies pin 1 and therefore the part's orientation. Getting it wrong at assembly rotates the device and usually destroys it at power-on.

Notes
The indicator must be echoed on the PCB silkscreen and in the assembly drawing, since the package marking alone is invisible once placed.
