Hi Jonathan,
I don't have exact numbers, but went through the math some six years ago
when we produced the VSIB boards.
A batch of ten boards is a seriously bad idea. In our case the startup
cost was about half of the total cost, we produced one hundred boards.
Most significant was the cost of the PCBs, producing a small number costs
a lot more. Work for buying components is the same for a small or large
batch, automated assemly line costs maybe 50 to 100 dollars per hour, you
can expect two hours setup time and ten minutes for every board.
And if you order a lot of boards it's a good idea to have them gold-plated
or stored in protective atmosphere (nitrogen I think), otherwise they
spoil in six months.
Cheers,
Jouko

Can someone please advise rough numbers (which one might use in a funding
proposal), for the cost to fabricate, assemble and test Roach PCBs? Please
assume donated FPGAs, or break out their cost). This application does not
not use large volumes, so assume a run of say 10 boards.
Also, is there a roadmap for compatible ADC boards? In particular we seem to
recall discussion at the workshop of an ADC, with two input channels *each*
capable of sampling at a 2 GSa s^-1 rate, which connects to a single ZDOC.
Is this called iADC2? Has this been built yet? Is there a rough estimate
of cost to fabricate, assemble and test?
Thanks for any guidance the list can offer.
Regards, Jonathan
