Thank you! Sorry, I mised EDIT.
All 3 different designs (yours, Mr Teal and ours) look really good to me, to be honest much better than the very complicated BFL's one...

Our board was designed to support 8 chips without any problem and with the maximum heat dissipation.

I am not an expert, as the engineers of the team did this job, but as far as I know
supply current for the core of each chip is 10A.
BFL power supply is approx 35-40A. that is why supports up to 14GH/s and not much more than that.
If BFL's board provided 80A current, it would be enough for 6 good quality chips - 28GH/s.
 
EDIT: If BFL's board provided 80A current, it would be enough for 6-7 good quality chips - 28GH/s.

Just to clarify that board is for 8 chips.

Hi Lucko,

Thank you for your comment.

We doubled the capacitors of the board the BFL published, which I believe that it will be more than enough for 8 hashing chips.
We will upload a photo of our idea soon.

Thanks for your comment.

You dont have to modify the PCB, which is in the picture.
The PCB is the same for boards from 1-8 chips.
The components are different and we modified them accordingly.

Our board is designed to work with up to 8 chips.
Singles have 16 chips as you very well said and mini singles have 8. 

Cooling will be challenging as they are many asics in close proximity, but
with the right cooling system can be managed successfully.

Cheers,

Chris

Thanks for the comment.
I absolutely agree with you, that the board that BFL released nobody can manufacture it as it is, as many pieces of the puzzle are missing.

We used BFL's design with some modifications. We are a group of engineers working in that project during the last month
and we have a lot of experience and facilities in the place we work to manage this project. The boards are already in the manufacturer
and we are waiting for both sample chips and boards to test them together and upload a video of our results.

Cheers,

Chris

Hi Lucko,

Thank you for your comment.

We use BFL's Single board which it can mount up to 8 chips.

The microcontroller connects all the ASIC in parallel. Also, Voltage specification for every chip is same
and current requirement is 100mA max. Means, in the peak load, the chips will draw 800 (8X100 mA),
thus no reason to increase power supply. I am sure that know that increasing the power supply,
sometimes, has a risk to fry the chips.

Boards cost $240 each including mounting of the chips, but without cooling system. I believe that it is one of the most
competitive prices in the market, considering how sophisticated and expensive is the manufacturing of the boards plus the
assembly cost of the ASICs which needs specific requirements and it is very risky for damaging these delicate chips to be done by hand.

Soon we will upload a photo of our boards!
Next week, boards will be ready and then they will need few more days for the assembly and the mounting of the sample chips.

Cheers,

Group Buy BFL Chips for Board production (Ready:Plug in-USB -Mining 24-32GH/s)
We are working on producing the PCB to mount BFL chips.
Boards would be ready to plug in the power and USB and then start mining (you will need a power supply)
Processing Power of the boards will be 24-32 GH/s (6-8 chips)

This group buy is not for buying single chips.

The finalising of the PCB will be in approx.2 weeks time.
Testing of the boards will take 1 week when chips are in our hands.

Of course, BFL ASIC chips will be the main components of the circuit.
As you can see on the BFL's announcement, minimum order is 100 chips.
I will place an order to BFL every time that the 50% of the money for the chips will be paid.
The sooner the order is placed the sooner the chips will be in our hands so the sooner the board will start mining.

About Chips Group Buy:
1)Paymet will be in BTC, but all prices will be in USD, as BFL accepts only USD for the chips
2)Terms of purchase and Considerations from BFL
3)50% of the chip cost will be due prior to the placement of the order. When the chips are ready and the final 50% is due to BFL, the remaining 50% will be due.
4)Pricing: i)Price for each chip will be 75$ ii)If you have credit chips the price will be $50, up to the number of credits that you have. If you want to buy more chips than your credits the cost will be $75
5)Board will have 6-8 chips, not finalised yet, so please do not place an order for less than 6 chips. If you place an order for 8 chips and finally 6 chips will be used 150$ (or 100$ if you have BFL credits) will be refund to you. If you place an order for 6 chips and 8 chips will be used, you will be asked to pay the difference prior to the shipment of your board.


About Boards Order and Buy:
1)Boards will be finilised in approx 2 weeks time.
2)Specifications are based on BFL parametres, which means that boards will have the maximum possible efficiency and they will not be experimental projects as many of us can do.
3)Processing Power will be 24-32 GH/s, depends on how many chips will be finally used.
4)Cost for each board will be approx 500$ (excluding the chips), with the best possible specifications for the maximum productivity.
5)The deposit for placing orders for the boards is 25$ per chip. This is 150$ for 6 chips and 200$ for 8 chips
6)You can finish with the payment of the boards when boards are ready and fully functional.
7)You are responsible for covering the shipping cost and taxes/duties on your end.

If you're interested, post in the thread.
Please, feel free to ask any questions.
