I was hoping to see scans of the actual silicon, but I guess that requires more exotic equipment. It seems to me that imaging the chips would be easier and better using a DSLR and a good macro lens.
- myth_buster 12y agoI was thinking the same. They could set it up with a tripod and couple of lights like this [0]. [0] http://globalflyfisher.com/gallery/digitizing/setup.jpg http://globalflyfisher.com/gallery/digitizing/setup.jpg
- lwhi 12y agoYou'd need to strip back the casing to see the actual circuits.
- zokier 12y agoZeptobars has some nice shots of silicon dies. As a random example http://zeptobars.ru/en/read/Nordic-NRF24L01P-SI24R1-real-fake-copy http://zeptobars.ru/en/read/Nordic-NRF24L01P-SI24R1-real-fak... I estimate that those images are taken with equivalent of about 60000 DPI. Even with that sort of resolution you can't really resolve the details in the smaller features. In comparison typical macro lenses have 1:1 magnification, so e.g. D800 DSLR with 36MP sensor would have theoretical maximum of roughly 5000 DPI, and I would expect the reality to be quite a bit harsher than that.
