Hi Gustaaf, 

Mike also asked a related question in the meeting. Kostas says 3 mo. lead time in an email, but I don’t have a firm date. I’m checking with Kostas+Cinzia now as we’re trying to start the purchase order. 

The other piece of this is the pre-production run. Kostas has said that we should plan at least 4 mo. to get wafers, but also no guarantees. There we are in touch with imec now and aiming for Nov 15. I think there is a good chance that, if we work quickly, we get the CV4 chips 1-2 months ahead of the preproduction wafers. I also expect that since JCET recently did this for the ALFE we could go from CV4 dice -> prototype BGA packages faster than the pre-production wafers -> prototype BGA packages.  

Best, Tim

Hi Tim,

Neither your slides nor the quote give a timeline to get the additional 400 chips.  Do you have a firm date if you put in the order soon?

Thx

Gustaaf
