Hi, does anyone know how to rotate the die or the bga before and after rotation? Currently working on a stacked die package. Would prefer to know how to do it after generation, but for completeness if there is a method to do it before that would be great as well.
I'm not sure what you mean by "before generation", but once placed:
In SiP, the Die Stack Editor tool has a rotation value for each die in the DIE tab.
In APD, you can select the symbol, RMB, and select "Spin".
