Re: [LABCOIN] IPO [BTCT.CO] - Details/FAQ and Discussion (ASIC dev/sales/mining)

Right. I have said all along that the PCBs look strange to me. However, I was only pointing out that you can't actually say that the chip pads are completely disconnected from the rest of the board, with the implication that Labcoin is a total scam. While there are some visible traces on the H-board, they're only on one side of the chip, the other four sides aren't visibly connected. (Of course, on that board it's possible the traces just can't be seen because they're under the chip and connected to visible vias.)

You understand that the three sides where you can't see any traces, the bitfury chips are just power, right?
Edit: If it's not obvious, the top layer of the Bitfury board is Vdd plane -- nothing else needed to hook up the power pins, no vias needed
