can I please get your opinion on what should be (or what is the required) wafer thikness for QFN package and BGA package?

Thanks! JJ

Hi JJ,

The wafer thickness for QFN is usually 10 mils.
Regarding BGA, it really depends on the BGA type, but 9~10 mils should be O.K. for the standard type.

Thanks,
Yovav.
