Dear All,


A customer asks us that the area of solder mask opening of MMA845x series is a little bit larger compared with general QFN package.

If you possible, please let me know why is the below figure recommended?


Solder mask opening : PCB land pad edge + 0.113 mm larger all around.

(Document Number: AN4077)


I would appreciate if you help for this question.


Best Regards,
