I don't think that is the same PCB they will use in final product. Just an FPGA friendly version for testing

its the same pcb for asic. they just put an fpga on there for testing and stuff.

Good news, looks like quality all the way.

So if I understand correct there will be 4 of these boards connected to a one board (the main PCB) inside the case and each of the smaller boards will have one ASIC chips on it, right?

Then why are there 4 slots for chips per PCB?

The chip pictured is only they as reference to overall size as it's a known component.

Let me ask again:

no the asic chip will take up all 4 of those areas.

So the single asic chip will have 4 areas with pins under, so it fits perfectly in these 4 places?

So these boards are upgradable?  You pull the chip out and put a faster one in down the road?  Or up to four faster smaller ones down the road?

It's solder balls, not pins, look up "BGA".  The chip gets placed on the PCB in loosely the right spot, and when the solder melts, the surface tencion pulls the chip into perfect alignment.

In that case I'd like to get an answer for this:

Let's see how much time until someone says "hey that connector can't handle alone 250 watts!!"

The connector can physically do 250W but it's totally not designed for that. If this is the final board designed to handle 320W, it seems weird to only have one 6-pin 75W PCI-E connector for power?

Not trolling, just curious.

Nice PCB, hopefully they can give us an estimated shipping date for the first units very soon. September is only 10 days away, knowing in which week the first units will ship by the first week of September would be a good sign.

Huh?

"knowing in which week the first units will ship by the first week of September would be a good sign."

lost on that one

KnCminer is finally getting the message that they do not have a finished product. The author of the article used the word "design" instead of "product". I pretty much appreciate they are now using the right language to show what they have accomplished so far.

Today we have our PCB’s back from the assembly house. These boards will each contain one ASIC chip and be individually connected to the main controller board. The Chip in the picture below is an FPGA which we are using to emulate the full functionality of the boards.
 
The entire space you can see in the middle of the  DC/DC modules (GE Critical Power DC/DC CONVERTER 0.45-2V 40A SMD)  will be consumed by our ASIC. 
 
We would also like to share some facts about our boards with you.
 
The DC/DC modules we have on our boards are the largest and best quality available from GE Critical Power. Each capable of 40 amps making the max available 320 amps per ASIC
Our PCB laminat is not standard either. It has been given extra thick copper layers and multiple power and ground plains which enable it to more than handle our requirements.
We will be using these boards to fully validate the entire setup. They will consume the same power, make the same noise level, produce the same heat and run the same RTL code. The only difference will be related to hashing.

ASIC PCB Board

We would also like to take this opportunity to explain our design philosophy.
 
Our entire design strategy is based on time to market, We have as you can see over specified the PCB by quite some way, our ASIC will only consume an absolute maximum of 250 watts and we know the PCB can cope with 320  watts. This is the level of design margins we employ.
 
So you can use the following to see how safe our design is.
 
We have used a VERY large package for our die, not because our die is large, but to make sure we can handle the power and heat requirements.
We have used more DC/DC modules than strictly necessary
We have used the most pessimistic/conservative estimates in all of our simulations. Including but not limited to Yield, Performance, Power and Heat 
For example while testing each part of the chain. We have tested our onboard Linux device to make sure it can handle up to 1.2TH ( The controller board also has and expansion for additional linux devices for future upgrade/ second generation)
 
Thanks

not sure, it seems like it might be from their wording, but that remains to be seen. i dont see how if the chip is soldered in place....

I really doubt that anyone was confused about KNC not having a finished product when they ordered or even just trolled on this forum, but thanks for clearing that up!

Each Minifit Jr pin is good to at least 9A, depending on the series it can go as high as 13A.

P=IV

6 pin connector * 9A * 12V = 648W max, so 320W is well within spec.

and what makes you think that's a 75w connector? Those leads are pretty thick looking to me, much more than 75 imho

So can we establish how big the ASIC chip is from this image?
Forgive me if that was answered already

Yes, as I said use the known Altera chip as a reference size wise.

[Phoenix1969]

it will cover the entire center area where you see space for 4 altera's

6 pin connector * 9A * 12V = 648W max, so 320W is well within spec.

Okay, thanks. I was wrong, obviously

By the way, the same current goes in and out so only 3 pins for 9A = 324W (hope I'm not wrong again)

Nope, you're not wrong at all - that's a good point.

Yes you can estimate it from any component with a known size (Altera Cyclon IV, GE DC power modules, 6 pin Minifit Jr connector, etc).
However it isn't necessary they have already indicated the package will be 55mm x 55mm (the lid is 43mm x 43mm).
