It sounds like a typical freezer cools to around -20C, I think the freezer spray I used directly on DDR chip, claims to chill to around -50C, but not sure how much the surface temperature decreases after spraying and how fast it warms up again.
- jacquesm 3y agoIndustrial freezers will go to -45, lab freezers to -85 before getting into really exotic stuff.
- azalemeth 3y agoLN2 is 77 K (-196 ºc) and dirt cheap -- cents/pence per litre. Most electronics works surprisingly well in it, at least until it warms up and the condensation starts to be a problem ;-).
- TeMPOraL 3y agoWhat about the material physics of losing some 220°C in a second? Won't things crack from this alone?
- azalemeth 3y agoThat's an excellent question and as you rightly highlight depends on things like ∂T/∂t that are perhaps a bit harder to control In practice, however, most electronics is fine (!) with the right materials – even a relatively bog-standard gaming CPU [1]...
