;Pin 1 in lower left, upper left, upper right, lower right. There is no standard pin out for the 4-pin DFN package and therefore there is no standard Pin 1 Zero Orientation. Never will be

. I have decided to just list which footprint types are Zero Component Orientation compliant on the assembly drawing. I don't expect answers to these problems, but I will list them in the hope you have some influence on the committees or that someone who does reads this forum. Pin 1

. But not everybody makes the footprint according to the IPC guidelines. Still an assembly facility is able to do it right. Assume an IC footprint is created with pin 1 upper left then that is the zero orientation, right

. Why not "Level A"? As I understand "Level B" will be more prefer in IPC-7351C ?
