Hi necplusultra

Very good question. I understand what you mean. Just let me explain why I couldn’t just supply the empty PCB and components.

Different from those discrete 74 logic boards which you could test point to point by yourself, the FIFO board has all the logic state machines running at decades of MHz inside the FPGA/CPLD. Even though you could solder those SMT components with perfect, you still have to face the problems of ISP and testing. For example, the on-board FIFO memory has 4 megabit cells, if some of them have reading or writing glitch occasionally, you might be noticed something wrong by listening, but you can’t address it.

Beside the FIFO board, another FPGA based dedicated test board was designed at same time. That test board could takes over all the input and out ports of the FIFO KIT, scan all the functions and cells by performing loop testing to make sure everything is good with bit perfect, as well as the S/PDIF board and the clock board. All of the boards for the group buy have to pass that test before delivery. Otherwise, it would be a big trouble for both of us.

Have a good night! Regards,

Ian
