Hi Yi,

I concur with Zhenyu's comments. I would suggest changing the 350_-100 
-> < 500 microns.

slide 7
well defined -> well defined and confirmed.
Have you spelled out somewhere what iTDC means?

slide 19
- >  say measurements are on hybrid; the the red not on FST-005 makes 
sense
slide 20
Will improve -> have improved
slide 27
Thanks for adding this
 ---  could you add #hours and resource (i.e person) doing the task
      Is there any allowance for weekends?
      Let's also revisit my spreadsheet.


We should add a summary slide - to stress that
 --production plan and QA procedures well defined
-- apart from final adjustments discussed ( precession pins, extra block 
) ready to start production
--  ...
