I'm not sure how they're attached (it looks like gold wire bonding) but the distance is a few mm.
- jacquesm 3y agoRight, thank you for digging that up. It looks like you are right that is soldered. Either that or wire bonded which is usually a weld, but welding would locally raise the temperature to the point that I wonder if that wouldn't potentially destroy the sample. Given the tiny current I wonder why they didn't use spring loaded contacts, but presumably they know what they are doing and this is just another 'why didn't they' style comment. So many questions about all of this, I would love to interview all these people, but I totally get that they have much better things to do right now.
