@noiob Because gold prevents oxidation of the surface

if you're asking why not use a HASL finish (where the board is coated in solder), the answer is surface flatness--HASL can be bumpy enough to make some many-pinned packages fail to get all their pins attached. the problem is particularly pronounced with BGA packages that have more than a few dozen balls, which is why you should always go for ENIG over HASL for designs with large BGA parts in them

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

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

@DarkOverord oh yeah absolutely

our favorites are the ones with reversible covers, like Ōkami HD, Ys VIII, and Collection of Mana

looks nice on the shelf without all the marketing stuff on the back
