Lists of PCB services by country?

morgaine

Has anyone come across anything like a table of PCB services available in different countries, preferably listing also their main features and typical costs as an initial basis for comparison?  As the OSHW movement gains popularity, I think such services are going to become ever more important, and maybe even directly take their input from Kickstarter projects.

 

It would be useful information to maintain collaboratively on a community wiki, but there's nothing like that on eLinux.org yet AFAICT.

    Interesting question.

    'every': no.

    'most': yes.

    I think that just taking 'topologically' and the implied 'as much space as you need' the answer is probably Yes.  Morgaine made the mistake of not also asking for the result to actually work

     

    I see the smilie and appreciate the laughter. image  In righteous self-defence though, my subsequent sentence nailed the question to engineering constraints:

    Of course at high speed where track length and impedance mismatch and clock skew are important, using extra real estate to get a complex circuit onto 2 layers may be total anathema.

     

    And of course there are many many more constraints than just those few and the ones mentioned by yourself and Victor.  One could write a whole book on the topic, and I'm sure that many exist.  Indeed, some areas like microwave circuit design are literally inseparable from layout design, because tracks are components in microwave circuitry and not just connections.

     

    But yeah, a board actually working would be pretty useful too. image

    Well, I think the subject is settled, but I'd like to have a final word...

    You talked about clock skew etcetera, which is a digital domain problem. The problem goes far beyond that sector, simple analog circuits sampling at 500Hz can have problems from one badly decoupled cap. I tell out of experience (decoupling cap GND for LTC1408 ADC)... It's just what the performance criteria are!

    And your beloved subject FCC regulation might be very troublesome even for a completely analog solution. If you have a switch mode regulator and do your layout badly you'll get some really difficult time at the EMC certifying lab...

    High slew rates also happen in circuits whose main operating purpose has nothing to do with high frequency processing (DC/DC converters, motor control, even operating a solenoid).

  • I've just created a website for comparing PCB manufacturers. It's PCBShopper.com. You enter your board's size, layers, preferred solder mask color, and quantity and it shows you the prices from several differe3nt manufacturers (in US dollars, including shipping to the US).

     

    I realize it's not everything you asked for, but it's a start.
