Edit 7-Nov-2012: BFL_Josh has posted both figures, so this bounty is now closed.

I will offer a 20BTC bounty to anybody who posts a measurement of the size of the die used in BFL's "SC" devices.  I'm assuming they all use the same chip.  It's really easy to get the die measurement from a broken device -- just grind off the plastic/ceramic top using a dremel and pull out a ruler.  I will be happy to escrow the bounty with a well-known forum member if you can present credible evidence that you're serious about this -- that way you can be sure you'll get paid before you totally wreck your already-broken device.

I need this figure in order to compute the η-factor for their product.

I will also offer a 20BTC bounty for knowledge of which process node BFL is using.  However, I caution in advance that it's not as easy to be 100% certain about that -- you can't just measure it with a ruler -- so claiming this bounty will be more difficult and will involve more verification (which might not even be possible) than the raw die-size bounty.  Please post here if you have any questions about what would be sufficient to claim this bounty; I don't want any hard feelings.

I have offered bounties like this in the past and have a history of paying promptly.

Both of these bounties become null and void if BFL releases the figures themselves.
