Questions about timing

Nanox filed a 6-K today, claiming:

On August 12, 2021, NANO-X IMAGING LTD (the “Company”) received a request for additional information from the U.S. Food and Drug Administration (the “FDA”) concerning the Company’s last 510(k) submission of its multi-source device, Nanox.ARC. The submission file is placed on hold pending a complete response to the FDA’s list of deficiencies. The Company’s response is due within 180 days from the date of the request for additional information.

The Company plans to respond by the due date which is 180 days from the date of the request for additional information. The Company expects to continue to optimize and develop further features of Nanox.ARC and is considering submitting an additional 510(k) application for the next version of multi-source Nanox.ARC during the fourth quarter of 2021, which will benefit from the FDA’s feedback on the first version of the multi-source Nanox.ARC.

This confirms that the Arc submitted for pre-market notification is not the one that Nanox plans to market, just like the Nanox.Cart.

But what is more important is the timing.  Nanox did not mention any of this on its Business Update webcast on August 16, which showed improved images, some new tube prototypes, and some fancy user interface, but no technical data and no evidence that the Arc prototype is actually working.

What does a chip look like

This is what a MEMS chip looks like, according to Nanox' new website.

Notice the green solder mask, the well-laid copper traces, and the polished brass.  Nanox claims that this chip is its core technology.  Is there a better proof that Nanox is a complete fraud?

Junk @ Yahoo remarks that Bezalel Academy of Art and Design seems to train their students well, even the ones that can't graduate.

Previously, the chip looked like this (see circle in the middle):

Here is the actual size, per Nanox tweet, with the dust specks, etc.

Update:  Here is a snapshot showing the chip being placed in a tube cathode by CEI, which claims in the video that is ready to manufacture the Nanox.Tube.  Again, circles everywhere.

Update #2:   For reference, Nanox technology white paper is still on the "new" website, but the link has been removed.

The chip looks like this in the diagram in that paper:

A white square instead of a circle in the middle - no brass, and no copper traces...

Here is the chip under "microscope" (as it says in Korean) from an RSNA 2020 video:

Update August 11, 2021:  Edited a bit, for clarity.

Update August 16, 2021:  The convicted felon Dr. Kim claimed at the Business Update recorded webcast today that these are "mems" chips manufactured at Nanox temporary "clean room" facility in Korea.  Note the dust specs on virtually all the chips (unlike regular chips, these need to have an absolutely-clean surface if mounted in the proposed Nanox x-ray tube, or things go poof as soon as the high voltage is applied, in theory).
