Is anyone going to make a thread for "Bitmine list of orders - December delivery", like the
excellent thread AFox did
?

Giorgio, the specs that were referred to in a previous post were the original, September ones, unless you've gone back and changed the package back to that flow-thru design you had then. I'm following the github specs, but there are still questions... is there anywhere else to go for answers, since nobody seems to be putting up any hard data here? Our collective is going to have hardware ready for A1s, and firmware & CPLD IP to drive it in just a few days, if we can finalize all the missing data. Otherwise, we'll have to use the time to put something else on the board.
Thanks for any help or pointers.
Oh, yeah - any more info on the design contest? We want to be certain to be the first with the best!

Sorry about that, we've been working hard these last weeks but we've finally made the final release of the datasheet of the CoinCraft A1 based on people's questions, we will be updating the GIT version later this weekend and maybe also open a thread for technical and engineering questions because, as you correctly said, this thread is more focused on the finished products (miners).

As of now no delays are known and the ASICs are in production at GF, scheduled for release at the initially planned terms.

BitMine received all the customer's funds, who have ordered miners through
https://shop.50btc.com/buy-asic
?
P.s. sorry for my english, I helped Google.

I think he's referring to the hacking of and theft of funds from 50btc.com.
He's asking whether you have safely received all of the preorder funds for Bitmine products ordered from 50btc.com, or if those funds may have been stolen.
Hack report is here:

Rant from our EE about the latest chip spec update:
1. Why are the designs less specific now Bitmine for the A1 chip?
2. Why haven't you specified the top-to-bottom pad distance, nor completely specified the position of the 0.2mm wide pads that carry the signals. Why have you done this? Was it on purpose? Worrying very worrying.
Please note your package has pads only 0.2mm wide and by not specifying your position this leaves us open to losing half of EVERY pad, if we are off in our guesses by only 1/10th of a millimeter. Only 100 microns, right? . And, that adds to the chips professed tolerance in your positioning of 50 microns. This is shocking. You need to include ALL the dimensions in the picture and table as soon as possible.
3.In response to a request to move the signals to allow for a ground escape between pins 8 & 9, you have doubled down by newly assigning pin 8 to Vdd (pin 9, a long vertical pad that forms the other side of the requested escape, is also Vdd). And, unfortunately, the pinout drawing is only related to the package drawing, in shapes. We should be happy that, at least, you fixed their pin naming to match the descriptive table that accompanies the drawing but we need Bitmine to really put out documents that are helpful
4. We will not be hand assembling A1 chips to the boards. These chips require robotics to have any chance at all and forget about hot-air-rework - if one of these chips is failing, we will have to scrap the whole board, at worst, or ship it with blue-wires and degraded capability at best.
5. Your promise of replacement chips for failed ones won't begin to cover the costs of discarding the whole board. We are going to design in a physical bypass for every chip, even though that will reduce our density by 20% or more in order to protect those doing DYI and others who buy from us.
6. At this point given what we are learning from Bitmine we expect to have two-three re-spins of boards with these chips, before we get the footprint, solder stencil, and reflow curves right. That's four iterations before production... please Bitmine help us reduce that if at all possible by providing some decent chip specs. We want to have a reasonably good chance to succeed with your chips.
Thanks,

Hi, please don't post these questions here but rather in the developers thread where they can be addressed better.

It's the 28nm chip distribution thread where you've already posted exactly the same questions, we'll follow up there.

My last two letters to you also went unanswered. Are you able to manage a civilized manner with their customers? You broke the rules. Bring back my Bitcoins!

Why do you ignore my emails? You have no arguments? Then simply return the Bitcoins and all will be well.
