When will you update the Production Status, steve?

Matthew,

Let me translate it. I wrote

" The test on the back end, lets say to catch the 2%
of failure is the gating item"

"LETS SAY."   

DVT verifies the design. That's been done.
PVT Verifies the Production. That's been done.
The PreMP will give us a number on the yield we can expect.

So, a PCB problem would be caught in DVT.
A Production problem is caught in PVT. 
The PreMP gives us a good final estimate at the production yield.

Yeild loss can come from a variety of things that are not design related,
but rather production related, like cold solder joint for example, or a 
bad batch of cpu, etc etc. These numbers are typically very very small. 

Now with something like a CPU  or GPU when you first go into production your
yield losess can be double digit.

Hmm.. 2% failure?  That's a bit high, no?  Does the pcb have some
issues?

I'm trying to clarify that now. Yeild is good there will not be another
cycle. Test throughput, how long it takes to test the phone is being
improved. One production starts we will just build continuously, The
build
process is very fast. The test on the back end, lets say to catch the 2%
of failure is the gating item, but that can be parallelized somewhat,
Then you have to figure the shipping. do I ship a lot per week, build
two
weeks and ship, etc. 

What is your dissertation on?

Just to clarify, what kind of time range would be needed?  A week (4
weeks?) for production, plus another week (4 weeks) for testing?
If testing shows problems, possibly another 6 weeks for another cycle?

I don't want some sort of indirect promise on the delivery date -- I
know it's too fuzzy.  Just some help interpreting the meaning of the
update.
Personally I'm already committed and don't mind having some more time
of productivity on my dissertation before the sudden halt that will
arrive when the phone arrives :-D
