This is really cool. In the demo, how do they just yank the chip off the board? I'd have assumed it would be somehow soldered on or something.
At 0:16 it looks like they're heating the board from below?

I can't see a problem, as long as the chips are not fraudulently resold. Beyond not using a resource in the first place, reuse is the gold standard in sustainability. As an engineer, I wouldn't use second hand components for prototyping. When prototyping you need to eliminate as much uncertainty as possible. I'd consider using second hand components in production, provided there is a cost advantage, supply is reliabl…
>I can't see a problem, as long as the chips are not fraudulently resold. In general, most components are only rated for 2 to 4 re-flow heating cycles before internal damage occurs. On some components the initial re-flow cycle brings the component into the rated tolerance, and for others the PCB forms a bimorph cantilever that physically fatigues the chip contacts/leads. Production yields are only part of the Infant…
...OK, I'll bite, what's the "sentient turnip" bit about?

Biting is considered bad manners... and don't worry about it. =3

As a member of the genetic tree, I’ll go out on a limb and suggest Autism. It seems a lot like Autism.

Not really, and most autistic people I've met are very focused individuals. Met one guy whose whole world was the Unreal engine source, and unless you were talking about that specific area... could care less who you were.
Be kind to yourself first, and maybe get outside for a walk. Best regards =3

Have any more information or sources? Would like to learn more

Looks like a hot-air rework setup. I've swapped chips by hand that way, once the solder is molten they'll fall right off the board. The hard part is lifting them away without accidentally dislodging anything else.

#20So I send in massive 60 drive jbod pcbs and you pay me more than 55c/lb? That's current clean pcb rate at any recycler. Boards are ~8lbs ea. Usually just tossing them unstripped to a muncher that pays 35c/lb for the whole 55lb jbod works out way better for time labor.
