Topic: [CLOSED] - Stumptown Miners - Avalon PCB Assembly - West Coast USA - page 17. (Read 30685 times)

Very interested. Would you offer selling the chips, and assembly service? I live in Canada in the Greater Toronto Area, let me know if there's anything I can do to help in terms of getting quotes and what not.

I'm in the Pacific NW as well, and am interested in a large order on behalf of Cognitive.

I live a few hours from BC, so feel free to get in touch to coordinate a pickup/dropoff etc.

The one I'm currently quoting only offers a 30 day money back guarantee by default. I'll send them an email regarding rework and let you know what they say.

Just got off the phone with the Corvallis-based plant. They'll be coming up with some pricing charts and getting them to me later today or tomorrow. They're sending someone out to meet me face-to-face, too, tomorrow. They stressed how important it is to have large batch sizes, which is quite true. If you're in a group buy, and particularly if you know some of the other people in your batch are in the Pacific Northwest, then see if anyone else might be interested in a high-price/low-turnaround solution. The more people involved here, the cheaper it'll be for everyone.

I got some more quotes from the currently-cheapest plant for low numbers of PCBs. This time I figured in panelization and got some slightly lower prices for fabrication. Assembly prices are still really high, though.

Updated local per-board fabrication prices for the K16:

16	$1,759.19	$1,224.09	$1,090.86	$1,007.64
32	$1,738.09	$1,206.12	$1,074.46	$992.79
64	$1,727.55	$1,197.13	$1,066.25	$985.37
128	$1,722.27	$1,192.64	$1,062.15	$981.66

I extended this out to 1024 boards, just for fun, and there's not much of a price break there beyond what 128 costs. With K64 batches of 32 and four days total turnaround, that would put the cost-per-board for fabrication and assembly at $1,286.27, before parts and my service fee. $358.21 for the same figures with the K16. So I guess the question now is, how much of a premium are you guys willing to pay for fast turnaround?

Anyway, I'm still hoping the folks in Corvallis can help me bring down the price. Right now I have pretty high hopes for them since they've been the most responsive and personable of the companies I've contacted so far.

I've also sent out requests for quotes to a few Washington companies, one California company, and one Arizona company. (The appeal of the last two being that they have plants in Mexico, which may provide a much lower price while still being close enough for me to do in-person pickup.)

Again, this is all tentative. Once I have quotes from everyone I've contacted so far and some finalized price charts and turnaround times put together, I'll see about getting escrow set up (hoping for JohnK or someone of similar standing) so people can start putting their bitcoin where their proverbial mouths are.

Escrow details

• The price per board will start pretty high and then drop as people ante up. Any overpayment caused by drop in price or rise in the value of bitcoin after you buy in will be returned to you upon production of your miner. Beware, though: if the value of bitcoin falls before the escrow can be released and converted to USD to pay for fabrication and assembly, you might end up owing more.
  
• If you have a special request regarding the size of the batch you want to be put in and how long you're willing to wait for such a batch, or if you want to pool your group buy chips with the chips from someone else's group buy, let me know and I'll try to work with that. The default batch grouping will be by group order batch, since I should receive those all at the same time, and processing in that way minimizes turnaround time.
  
• The escrow will be released to me when it comes time to manufacture the miners. (I don't have the funds to personally cover the cost of getting all these miners made.) Whoever holds escrow will also hold my personal information, to be released if I make off with your bitcoin.
  
• Escrow will not be available until all domestic pricing charts and turnaround times have been finalized. If demand results in enough miners being ordered and paid for via escrow to exceed the numbers in the pricing charts, I'll get additional quotes to cover the new requested quantities plus some buffer room.
  

I'll also see about getting offshore production quotes together so we can talk about possibly switching to those pricing models and plants in the event that difficulty skyrockets enough to negate any earning advantage resulting from the quick turn-around offered by domestic production. Of course, if the whole thing falls apart at that point, then I understand: my value proposition is quick turn around by using domestic companies and face-to-face hand-offs whenever possible.

For those of you holding out for the K1: I will be gathering quotes and taking orders for the K1 miner as well once the BOM and Gerber files are released.

Do the assemblers offer a warrantee for their work?
Say a few assemblies don't work due to a manufacturing defect will they repair them?

Catching up on responses to comments I missed earlier:


Ah, right. That makes sense. So... maybe Canada will be the way to go. I tried emailing him, but the address on his website didn't work. I'll see if BkkCoins can give me a working address.


No. I basically just gave them the number of SMD, through-hole, and QFN components, along with the number of BOM line items. Some of the other plants (like the one in Corvallis) have required Gerbers and a BOM, but not the one quoted here.


Maybe. Terrahash, the other US-based distributor currently making waves, will have the last two advantages as well. I imagine turnaround will be faster with me, but how much faster is the vital question here. As difficulty goes up, the advantage to be had from moving quickly begins to weaken, until eventually cheaper with longer turnaround is a better deal. I intend to keep price charts going here so we can figure out the best deal for all involved.


Thanks! Sounds good.


Nope. I split the two phases of PCB construction into two tables. The top one is for fabricating the bare board, and the bottom one is for placing and soldering the components.

Ok, ill watch this thread for new infos then... I added you for now without a price and with a 16 chip and a 64 chip miner.

Exactly. The only scenario in which I buy the set from BkkCoins is the one where they get dev chips far enough in advance of the rest of us to allow receipt of that set before I start receiving Avalon chips. I will be paying BkkCoins a licensing fee.


They don't. The prices and times quoted are for assembly and fabrication only. I still need to price out parts. I have a call with a promising Corvallis-based plant in about two hours, and I may be able to get some firmer prices from them. (They specialize in end-to-end PCB construction for startups.)


8 K16 boards, not panelized. I wanted to err high in my initial estimates as I'd hate to over-promise and under-deliver. And the turnaround time for assembly is after the boards are done being fabricated. I intend to begin fabricating the boards as soon as BkkCoins confirms the design with a prototype, so we may gain some time there. (Depends on how quick BkkCoins' turnaround is.)

Seems that way right now. Again though, nothing is fixed yet. I still have a whole state full of plants to get quotes from. And I'll be on the phone with one of them at 3pm PST, so I'm pretty optimistic about that.


I ship the miner back to the owner. No plans for hosting as of yet. I might hash something out if there's demand and I end up having enough time.

Yeah, I've seen that. My value add is getting the boards sooner than you'd be getting them with Terrahash. It'll be more expensive, but you will be mining sooner. Particularly if you're in the Pacific Northwest and can do a face-to-face pickup. (I know the thought of my complete set of 8 K64s, or 30 K16s, going through the mail makes me nervous.)

TerraHash is assembling 64 chip boards for 1.99 BTC (around $230.00), and the 16 chip boards for 0.75 BTC (around $85.00). Definitely worth checking out.

I'm in for 32 chips (2 boards).

Chalk me up as interested, pending some firmer dates/plans/etc.

I'd be in at 250 chips

About to. I imagine it will be as well. I saw a couple plants that said 16 inch boards were preferable, so I'm guessing that's the size of the stock material they're working with. I'm going to run some different numbers through the online quote forms and compare the K64 to the K16, and then look at whether the K16 can be panelized and broken out later for greater savings. (I was running quotes for one PCB per array, as I wanted to make sure the price erred on the high side.)

I'm also expanding my search out to include plants in Washington today. That may turn up a cheaper option.


Well, a little more than $312. I haven't really priced parts yet. The parts, according to the BOM, would be about $26.32 per board. But a couple days ago I did some shopping around and there are some snags the BOM doesn't call out that bumps up the overall price. All the assemblers I've found so far require components to be on reels, which requires either buying enough components for a couple hundred miners or paying the supplier a $7 reeling fee per BOM line item. There are also a couple components that only come on reels of 5,000. (Those ones are only $15 for a reel of 5,000, so it's not too much of a price bump.)

So I'm looking at around $312 per board (4 day/5 day choice) if we have at least 32 PCBs manufactured and then assembled, correct?

16 chips at 282 MH/s = 4.512 GH/s.  My end cost for chips is currently $9.42 each (.08BTC) so a K16 would end up being $462.72. That doesn't seem too crazy if my math is remotely correct. AM blades are selling for 50 BTC each at 12.89 GH/s.  Of course by the time chips are here it could be a completely different story.

Wow, that's extremely expensive. Did you get a quote for the K64 as well? That might be more affordable on a chip-per-board level.

I travel back and forth to Portland a LOT.  Would love to meet you guys and discuss.

I will check in my neck of the woods. Guess if we got 64+ boards together it might be ok, but....it's still pretty pricey.

I was hoping to keep the unit cost under $150 for assembly....

Did you just give them the parts list off GitHub and they gave you a quote based on that?

I can't open Klondike's CAD files off GitHub.

We are a free trade zone, here in North America, built and assembled should be duty free.  Call up customs, they are very helpful with this.
