is Rogers 4003C *supposed* to smell like that?

fun fact again: most people know that iron, cobalt, and nickel are ferromagnetic, and at STP that's all you get as pure elements go; every other ferromagnetic or ferrimagnetic thing is a compound

but if you go just slightly colder, pure gadolinium is also ferromagnetic! it's not ferromagnetic at STP because its Curie point is somewhere around 18 °C

one reason for the nickel is as a barrier layer between the gold and copper, yes, because otherwise you get copper-gold intermetallics that can cause problems, but the other reason is to provide a very wettable surface under the gold for the solder to stick to

copper is even more wettable than nickel, but it dissolves into solder very quickly

random fun fact we learned yesterday: the gold in ENIG finished boards is not there to be the thing that the solder wets and sticks to, it's only there to protect the nickel (which is a metal with very good wettability)

the gold layer in ENIG isn't as thin as it is to save cost, though that's part of it--it's intended to completely dissolve into the solder, exposing fresh nickel for the solder to wet

you ever just think about how weirdly *amazing* kirby air ride's music was?

YbBiPt is an intermetallic compound that has some interesting properties, chief among them being that it sounds like some kind of weird raspberry if you try to say the chemical formula as a word
