This BGA pcb sort of thing is impressive.

12, maybe 14 layers and phenomenal traces/spaces.

wow, I see three tracks between balls, it's gotta be something like

1mil trace/space

Wow, I see 6, maybe 7. ( Just North-North-East of the lighter area near the lower left corner, picture 7 )

This chip also has internal bypass caps... somewhere.

Probably potted in the epoxy on top. 0201 capacitors are tiny enough.

What does it go for?

The Arria II GX95 version is about $850 each. 780 balls.

John,

Do you know dropbox can open you up to some very serious security issues that Chinese hackers are actively exploiting?

You'd need 780 balls to put something that expensive in a design. :)

sorry couldn't resist...

hard to tell if it is 7 tracks, or 3 tracks and 4 spaces

Actually it's consistent with high-end CPU's that are made in much larger volumes.

A few years ago, the Virtex parts I was using were $3800 each. I thought that ridiculous, until someone told me that the three CCDs, in front of one, were $5K each and the prism in front of those was $45K. That was only one of the parts (no idea how much the FLIR FPAs cost). Your tax dollars at work. ;-)

;-)

I've heard of high-end FPGAs listing for $12K. I saw a board at a trade show, part of a logic simulator, that had 64 FPGAs at $3K each. A typical simulator had five boards or some such.

This is the most expensive one that Digikey shows in stock (6 pcs) atm:

1932 balls. They list a few more at $22K+ each.

One or two of them equals the price of a foreclosure home in some areas.

It's amazing they stock them at all. They couldn't be blamed for shipping those straight from the manufacturer.

I wonder who exactly owns such stock, even if Digikey maintains physical posession of it.

Good point. I doubt that anyone actually pays that price for them, either. Those big enough to buy such things undoubtedly get a better deal.

Oh, I like the pricing $18,389.99!

$18389.99 instead of $18390 really make it look less expensive :-)

Thanks, Fred.
