Fig.1 typical dimension of QFN package
Above is the typical dimension specification for QFN package. I cann't find the corresponding "T1" as in Fig.1 in the DRS4 documents, nor any of the tolerance of the dimensions, which are usually expressed in the form of a range between a min. value and a max. value.
So will you specify the dimension of "T1" and "W1", and the dimension tolerance of them?
Thanks and best wishes!
