UpdateIt doesn't make sense to have the boards fully populated and then add the ASICs. You'd have to reflow the boards twice, and there's no reason for that. Maybe Friedcat will confirm, but I would guess that they had the PCBs and stencil ready to go, and will now fully populate the boards. This would be similar to Avalon, where they designed the PCB and tested it with simulated signals prior to the arrival of the ASICs.
In fact we have two pcbs. One for testing and one for mining. The latter is also a demo-version with respect to the first batch, because besides mining it will be used for profiling (mainly heat dissipation) to make our mass production stage better. The pcbs for testing are single-chip ones that are not modular, but it's simple enough that we could make hand fixes when anything goes wrong. It helped us much in determining and fixing a lot of small problems.
While the pcb for mining inhabits many chips, and are modular in a sense that controllers and dc/dc adapters are pluggable and replaceable. They should be are a being assembled with chips and other components by our assembly service with outsourcing contracts.
What we have done in the past week:
1. Making order and sending the pcbs, chips and other components to the assembly service.
2. Negotiating for the final renting contracts with workshop-typed land providers.
3. Dealing with mechanical parts (mining device holders, heatsinks, fans and air-conditioning).
4. Placing the mass production order to the chip foundry and making the first part of payment.
5. Getting noticed that the rest 6 wafers of the first batch in the foundry have only 6 layers left.
Thanks for all shareholders' patience and we are also very eager to have our devices mining. The service for pcb mass production and assembly has a very effective production line and responds very quickly to us, thanks to the glow competition of small and medium electronic businesses in Shenzhen.
In addition, if we are lucky enough, other current and potential mining device producers, if they ever have any step of production outsourced to Chinese businesses, will be delayed by the Chinese New Year (Feb. 10). It will be a long vacation (typically 7 days, plus a prior week and a succeeding week of low working efficiency from holiday syndrome and some of the employees' annual vacation-New Year vacation requirements).
