smd orientation for pick and place
It's also worth considering the direction the board passes through the pick-and-place/wave solder line. In my experience, the pick-and-place programmers can handle the part rotation issue when they set up their programs.

However, ICs, especially those with fine pin-pitch, should generally be sent through the wave solder process with pins perpendicular to the wave. Otherwise, solder bridges between pins are much more likely to form, ruining your PCB assembly or setting you up for lots of rework.
