Tooling (setup) - which is a once-only charge with them unlike some fabs - $37.80. Per board (area) cost $0.57. All up cost $94.80 or 95c each.

Well I have not personally had a request for anything like that, I will keep you in mind if it happens. For equipment, before such a fast scope, on my wish list would be a good *cheap* spectrum analyser Got an email from Altera today, about ASTA and their FPGAs. If I understand it right, that could mean eliminating a PC mobo... and then there are those 18 Gbits / second serial links sigh... http://www.altera.com/education/webcasts/videos/videos-sata-soc-solutions-40nm.html

I should not have to pay more because there are separate >functional areas on the board.Case 1 the PWB fab house sees exactly one layout for all variations=20 and does not populate the boards; don't ask, don't tell -> no premium. Case 2 the PWB fab has to differentially stuff the boards -> lots of=20 extra housekeeping on their part; depending on volume, ordering them=20 separately may get better deals.

They see different functional modules on the PCB and want to charge more. They don't have to do anything else with the additional designs. This usually cause delays on the job, so I either pay or suffer the delay. It's the industry's best kept dirty secret.
