ADXL001 PCN for protective CAP

Thank you for your post.  Normally, for products that are in production, PCNs are listed in the ordering guide area of the web site. 

For example, on the ADXL357 page, it is located here:

Having said that, the ADXL001 is obsolete, which removes the support for PCN service online.  

With that in mind, may I ask for the intention, or desired outcome from this query?  

I can do some research, but need some relevance to properly target that activity. 

Thank you! 

I encountered two ADXL001 device and performed delid, have observed that these two have different die design, one is capped die and the other is uncapped die.

Is there a difference in functionality for these 2 type and is there a PCN for the changes? 

Hoping for your kind support on this matter.

If I remember correctly, we moved to a capped die approach, due to loss of manufacturing support from the uncapped process provider, at that time.  While I was not intimately familiar with this one, there was substantial effort to maintain the resonant frequency, mechanical gain (Q) and other key performance metrics. I hope this helps. 

Thank you, for the support. Hope you can still provide the PCN regarding the change from uncapped die to capped die for this device also.

OK, let me see what I can find... 

I have found two things: 

1. We cannot supplement our standard PCN system, by sharing such files though this forum, but you can make a request through your normal interface with ADI's manufacturing team. 

2. This case appears like something that one of my colleagues already addressed through direct email dialog, perhaps with our end customer. 

Sorry I can't support your request directly, but the information does appear to be available, through more official channels.  

Take care! 

Thanks for the support.
