Hello,
I have a question.
What is the true way of finding a PCB footprint of ICs?
For example I can not find the IC's footprint by its part number. But I know it is a QFN 56 7x7 .
How can I find the standard dimension of these packages to build its footprint by my own?
I have found many dimension for this package!!
I even found different footprint in Snapeda.com
please guide me,
Thanks ,
