´thank you. One thing, can you have a small border around the board 5mm? with such a border it is much easier for assembly lines or something like a pulling border?
There is almost that now but there are a few parts within 5mm of the edge. Not sure about that as I didn't really design it for automated assembly lines (something which I know nothing about). I suppose you could use a slightly bigger board size.
As I asked several companies for manual / automatic assembly (EU), most of them said they would do only manual assembly because of the very small (0402) components. However there are larger companies can do automatic assembly, but you have to order 1000+ boards and pay for the programming and assembly line setup about 1500 USD!
Imho below 100 boards manual assembly is the first option, however its more expensive.
Hi,
I have a company I have worked with for automated doing with small series from 1 to 200 normally.
normal price for a prototype board is 400 for the pattern and then the price vary on how much and what components are used.
For example a Ztex Licence Production without the fpga chips (quantity orderd 25) 70 per Board excl. VAT and when you want 1 > 250 (I have done it last year)
Example calculate for 1 Prototype:
1. 400
2. 250
3. Avalon AsicChips (1-16)*7
4. PCB Board: ~10 (plus initial costs 50)
5. Heatsink 10
~ 850 excl. VAT
mass production (from 25++) price for 1 Board inclusive asic chips:
1. 70
2. Asics: (16) ~112
3. cooler/heatsink 10
3. PCB: 10
~200 excl. VAT
so 4.5gh/s should be possible with 2.5 BTC :-) or in 45 / gh/s
Please Note this is only a calculation the endprice will vary.
Posted in another thread, I think this should be here.

I asked several assembly companies. Finally I got one cheap and realible offer for manual assembly: ~ 110 USD, 10 days. This is for very small amount of boards, asked them to assembly 2 PCBs. When we order 100+ the price can go lower.
The companies I asked can only assembly the boards manually, because of the really small packaging of the components (0402 capacitors and thermistors).
1x K16 miner price would be:
16x Avalon chips: ~ 151 USD (based on 16 x 0.086 BTC x 110 USD)
1x K16 board: ~ 9 USD (based on current
https://github.com/bkkcoins/klondike/blob/master/docs/K16%20Parts%20List.pdf)
K16 parts: ~ 33.74 USD
Manual assembly: 110 USD (incl. VAT)
Summary: ~ 303.74 USD
4.5 GH / sec hashing power for this price.
Please note: this is for ONE board assembly with 16x chips without delivery costs for EU.
