Understanding ASIC Miner Chip Configurations

I’m diving into ASIC miners and curious about what materials they use. I’ve seen multiple chips per hashboard and several hashboards per unit. But for the specific models I’m looking into, like the S19, S19j Pro, and S19 XP, I can't seem to find solid info on the number of chips or their sizes. Anyone got reliable sources or at least some insights?

Most detailed specs are kinda hard to come by. I suggest checking out AliExpress for chips, they’re pretty cheap, just a few bucks each. The BM1362AJS chip is used in the S19j and S19j Pro. The Pro’s hashboard has 126 of those chips. If anyone else has dimensions or other specs, that’d be awesome!

Here’s a cool table from ZEUS MINING about Antminer ASIC chips. Just a heads up, the number of chips varies even within the same series. Like, the Antminer S19 95T has 76 chips, but the 90T version can have 88 or even 126. The S19j Pro has 126 BM1362 chips while the S19XP has 110 BM1366. For exact counts, check the markings on the hashboard.
