Package Generator lacks QFN with center pad

From what I can tell, the Package Generator doesn't have an option to create a QFN package which has a center pad, requiring a manual edit of both the package and its name in order to add that pad. I think this would be a useful enhancement because, in my experience, the majority of QFN packages have center pads.

Hi @scott,

This one is on the list, stay tuned.

Let me know if there's anything else I can do for you.

Best Regards,

Hi Jorge,

Support for DFN packages with custom number of pins (say 8 or 10) is also missing. In fact this could be easily done with the QFN generator if we could set the number of pins (E-side or D-side) to zero.

Yeah, I've been using that to make leadless two-sided parts by creating it and then deleting the extra pins as a QFN. Hopefully easy to add!

Dear users,

Thanks for your feedbacks!

Things to note:

Current DFN and QFN generator uses different IPC solder goals to derive their respective pad outputs. So please be aware that the results could be different while creating a Dual Flat/leadless two-sided parts by modifying the generated QFN package.
