Returning to IPC, at least IPC defines three distinction criterions which could be combined very arbitrarily depending again on your design goals:. Producibility Levels When appropriate this standard will provide three design producibility levels of features, tolerances, measurements, assembly, testing The QFN Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined.

kpc Finish is available on any page of the Wizard after selecting the component type. The DPAK Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined. These tolerances are assumed by the Wizard in order to calculate a corresponding PCB footprint. Use the BGA Package Layout Options page to define the basic ball layout by adding or removing balls and changing the grid type.

Since the centroid file or similar, by another name generated by EDA software tells the PCB assembler company how to rotate each component to be placed typically by a pick and place machineit is vital that there is agreement between the PCB designer and his or her software and the software of the assembler which interprets these files and generates instructions for the pick-and-place machines on how the component is oriented with zero rotation.

Use the drop-down to select the Hull side type: I believe it has to do with the standard related to tape and reel feeding, but I will appreciate a more elaborated answer.
