    Circuit maker (Student version) is also another free software that proves to be useful

  3. Printing technology has been forging ahead rapidly
    and developments will soon make it possible to manufacture all sorts of sophisticated, smaller and cheaper electronic and communication products.
    In the warp-speed world of technology, five years is an eternity.
    It’s best regarding automated companies make
    use of Printed circuit boards such as IPC-6012 Class three to
    make certain reduced sign decline in addition to understanding inside frequency when shifting signals throughout these units.

  4. I appreciate your sharing very much.It’s very useful for us.
    And I think It would be good to see added to this list.
    It offers schematic capture, spice simulation and PCB design – including Gerber download – for free.
    EasyEDA also offers low cost PCB manufacture and assembly.

    There are several free EDA tools around and some excellent tools such as KiCad and gEDA but the reason I thought people might be interested in EasyEDA, is because it has a few twists to it.

      i) it’s web based so, with nothing except a bit of javascript to install, it can be used by Linux, Mac and Windows users and – if they have a big enough screen – Android and iOS users too;

      ii) work can be shared and – with a bit of agreement on who saves what, when via a 3rd party instant messaging service – it supports collaboration;

      iii) it has some pretty impressive import and export options such as importing Altium, Eagle and LTspice files and exporting spice netlists and svg, png and pdf files for documentation. It also uses open standard JSON format files internally so it’s easy to do some quite whizzy things just using a text editor;

      iv) all use of the tool is free even to the point where the user can download PCB Gerbers and send them off to any PCB supplier;

      v) it also offers a low cost PCB service: PCBs can be ordered directly from within the tool (this seems to be the way the money is made to keep the whole thing afloat);

      vi) it can even be used without registering with files being saved in an Anonymous mode that works a bit like pastebin where files can be retrieved and shared just by their urls.

      There are lots of examples on the site and a useful tutorial.'s easy to drive .

    Just try it at:
