First Look at BFL's ASIC Hardware

[Inaba]

Close... it was a nice fat CJ on the throne.

Looks like somebody got a booboo, im sorry did i hurt you? 

[Inaba]

The day you are more than a foot note on my toilet paper is the day I stop reading Bitcoin Talk.

[CJGoodings]

Some ego, i guess i will never reach your stature... as a talking piece for a massive walking scam.

[Inaba]

You're right, it's hard to reach my stature living in your mom's basement, eating Cheetos.  Good luck, though.

That is almost sig worthy!

Wow... worked hard on that, did you?

[CJGoodings]

Well somebody ate their wheaties today, done playing ethug?

Is this Dragonball Z?

Are we going to see watercooled ASICs?

Do you mind NOT posting ON TOPIC replies, please?

Sheesh, some people.

[jjiimm_64]

Mistakes like that never get passed me.

I passed some gas

edit: this wasn't the topic?

[CJGoodings]

I would love to see the SEC debrief on this, some intern is explaining it to the rest of the room with a report he passed around.

Intern:
"Yes sir, here are the specs they are advertising"
Boss:
"What about a photo of the product?"
Intern:
"Page 3 sir, its the black box looking gizmo."
Boss:
"Its stated that the image source is verified, where was it located?"
Intern:
"Facebook."
Boss:
"............."

"Your a fucking idiot."

I'm trying to work on that, need mechanical drawings

[mrb]

No, I'm not a miner. But I know a scam when I see one. And this is a scam. S.C.A.M.

You are wrong, and you don't have enough self-confidence to put your money where your mouth is by betting against BFL here: http://betsofbitco.in/item?id=665

Why doesn't this board have pads for decoupling capacitors for the ICs? Usually they are placed on the bottom of each chip!

Here's a raspberry pi bottom.

Very interesting. It looks like they have two power phases, each with 6 ST1S30s. The ST1S30 is rated for 3A, so assuming all 12 were running at full output current you'd have 36A or so of whatever the rail voltage is, commonly 1.2V.

It's also interesting if they actually are using ST1S30, since it has an absolute maximum rating of 7V and the common input voltage is 5V. I wonder if they're bringing 5V in through the barrel jack, or if one of the other chips is meant to convert 12V->5V. If there was, I'd guess it would be the one at the top left that looks a little floating off in space in the render, but without knowing what actual part they used it would be hard to tell if it's capable of outputting 10A.

It greatly speeds production and reduces cost if you can run components on a single layer. Again it's hard to tell from the renders because the schematic capture and layout software often does goofy stuff with a 3D model (especially if BFL is using their own part libraries), but it kind of looks like the ASICs are packaged in QFNs as opposed to BGAs. If that's the case you'd actually want the decoupling on the top layer, and you can see some of them around the ICs.

Here;s the Deep crack ASIC board. Each Deepcrack chip (qfp) has clearly visible decoupling caps.
