Eurocircuits and V6 .brd files

Former Member
Former Member over 14 years ago

Just mailed two designs to Eurocircuits this afternoon made by Eagle V6.

Received a reject as 'does not look to be a valid .brd file'.

I wonder if they know about the changes in V6?

    The new version is out only some two weeks. Give them some time. Board review

    for eurocircuit is in India to my knowledge, so perhaps even some more time

    is needed.

     

    Also think about delivering Gerber RS2xx. That way, data is fixed and not

    subject to subtile differences in setup.

    Hmm, that will likely stop it solid. Altough Eurocircuits did build good

    boards based on .brd files for me in the past. Not having generated

    Gerber files at all, I will have some reading to do, as we want to build

    prototypes for customers in a few weeks. This is the moment where I

    regret to have upgraded to V6 early.

     

    In the online help, 'GERBER' does not do much, but I saw a gerber.cam

    file. Should the result be a collection of files, like a drill file etc?

     

    Cancelling and trying another board house right now might get me in the

    same problem again.

    Well, that did not look that hard. Found the instructions, generated

    drill file and a 4-layer Gerber, zipped them up and updated my order.

    Hopefully that was the right way.

    It is very important to verify that all the necessary files are there,

    contain the correct layers and are not mirrored.

    Review the tutorial that ships with Eagle, found in the DOCs folder.

    Section: Output of drawings and manufacturing data.

     

    Gerber is simple  and nothing to be affraid of. Note a drill file will need

    generating as well as the multiple files for the layers considerd Gerber.

    Before shipping gerbers, view them yourself. using a viewer. GC-Prevue and

    gerbv are a couple to try.

    It also helps if you understand the order of the process steps the

    manufacturer uses. That way you don't flipout when you view a Gerber copper

    layer with no holes depicted.

    Eurocircuits have a page

    http://www.eurocircuits.com/index.php/technology-guidelines/pcb-layout-data/117-cadsoft-eagle-brd-to-gerber-conversion-guidelines

    Hi Robert,

     

    Have a look here:

    http://www.eurocircuits.fr/images/stories/ec09/ec-design-guidelines-englsih-1-2010-v3.pdf

    They describe the data formats they accept.

    And this one

    http://eurocircuits.info/phpBB3/download/EC-Eagle-Guidelines-ENGLISH-1-2010-V1.pdf

    on how to create Gerber files using Eagle.

    There's no difference between version 5 and 6

    Hello Robert,

     

    We received your order at Eurocircuits.

    We would like to draw your attention to the following message on the EAGLE-CADsoft website. It might be related to the problem you experienced.
    --------------------------------------------------

    WARNING: Most unfortunately, after the whole release process for version 6.0.0 had been finished, it turned out that there is a bug in the polygon handling of the CAM Processor.

    If a board contains signal polygons that have their "Orphans" parameter set to "off", and the CAM Processor is used to generate production data with the "pos. Coord" (positive coordinates) option turned on, and if this actually leads to an offset in the CAM data, it can happen that parts of the signal polygons are not drawn, even though they are not orphans, and vice versa.

    This may lead to missing electrical connections or copper in places where this is not intended.

    As an immediate workaround you can turn the "pos. Coord" option off.

    We are working on a solution for this and will release a fixed version as soon as possible.

    Sorry for the inconvenience.

    ------------------------------------------

    It is advisable to check any result before releasing your data.

    If Gerbers are generated, these can be checked with an independent freeware Gerber viewer GCPrevue for example (www.graphicode.com).

    Luc

    Well, the 4 layer boards came back with a layer missing. I used the ULP

    to generate the Gerber files for a 4 layer board and send it to

    Eurocircuits. When asking confirmation by mail, the answer was that it

    would be processed as a 4 layer board.

     

    I downloaded GC-Prevue, but can't make sense of it (it asks for file

    extensions that are not part of the many Gerber files I created). The

    HELP menu assumes that you know how to operate it.

     

    Is there a document that describes how to open Gerber files in GC-Prevue?

     

    Which board house accepts .BRD files of Eagle 6? I made 100+ boards this

    way, never a problem.

    To use GC Prevue, open the program, then go to File>Import and select

    all of your gerber files and then you get a chance to select layer

    colors etc.

    Doug, thanks. At least I see something, so I repeated the whole process:

    Followed Eurocircuits guidelines for a 4 layer board:

    - Ran CAM processor, selected gerb274x-4layer.cam, activated Dimension

    in every layer.

    - Processed the job

    - Did the same for the drill file.

    - Zipped it all up.

     

    Imported the zip file in GC Prevue.

     

    End up with 3 Hole/Rout layers (.dri, .drd, .gpi),

    and 10 Unknown physical layers P1-P10 with extensions .pls, .plc, etc.

    Displayed like:

     

    Physical layers

    (v)P1 Unknown "Qbus_V21.pls"

         +(v)P1.1 "Qbus_V21.pls"[a001]

    ...

     

    GC-Prevue reports 0 errors.

     

    Would this be related to gerb274x-4layer.cam not being compatible with

    Eagle V6?

    Robert

     

    Im curious, what layers did you draw om and what layers does the cam file

    process?

    I would not recommend using any cam file unless you really know how it

    works.

    - Ran CAM processor, selected gerb274x-4layer.cam, activated Dimension 

    in every layer.

    - Processed the job

    - Did the same for the drill file.

    - Zipped it all up.

     

    Imported the zip file in GC Prevue.

     

    End up with 3 Hole/Rout layers (.dri, .drd, .gpi),

    and 10 Unknown physical layers P1-P10 with extensions .pls, .plc, etc.

    Displayed like:

     

    Physical layers

    (v)P1 Unknown "Qbus_V21.pls"

         +(v)P1.1 "Qbus_V21.pls"[a001]

    ...

     

    GC-Prevue reports 0 errors.

     

    Would this be related to gerb274x-4layer.cam not being compatible with 

    Eagle V6?

    Hello Robert,

     

    You don't need to process the .dri file (= ASCII info file) or any of the 

    .GPI files (same). All drill info is contained within the .drd file, at 

    least when you use the EXCELLON drill device.

     

    In the Eagle documentation (help > generating output) you can find what 

    the CAM extensions are used for:

     

    -


    File   Layers               Meaning

    -


    *.cmp  Top, Via, Pad        Component side

    *.ly2  Route2, Via, Pad     Inner signal layer

    *.ly3  Route3, Via, Pad     Inner signal layer

    *.ly4  $User1               Inner supply layer

    ...                         ...

    *.sol  Bot, Via, Pad        Solder side

    *.plc  tPl, Dim, tName,     Silkscreen comp. side

    *.pls  bPl, Dim, bName,     Silkscreen solder side

    *.stc  tStop                Solder stop mask comp. side

    *.sts  bStop                Solder stop mask sold. side

    *.drd  Drills, Holes        Drill data for NC drill st.

    -


     

    The "unknown" layers in GC Prevue are just because you didn't gave them a 

    name. While importing you are given the chance to name the layer and 

    indicate it's purpose. 'signal', 'soldermask', etc. and 'top', 'bottom', 

    etc. are indicated in drop lists.

     

    I don't think you should (need to) activate the dimension layer in every 

    layer. At least I don't. I make one layer that I call .fab, where the 

    'dimension' layer is included along with the 'drills' and 'holes' layer. 

    When you plot every layer with the GERBER_RS274X device you should import 

    them (as Doug said) as a "physical layer". The .drd file should be 

    imported as a "hole /rout layer". When 'autoguessing' the settings in the 

    drill file GC Prevue often get's it wrong. If hat happens, you'll see the 

    drills plotted in (totally) wrong places. Just delete the hole/rout layer 

    and the associated aperture file and start the import again. This time, in 

    the "Import - Verify File Information" window, right click on the NC drill 

    file and choose "Modify format parameters..." . look for the right 

    settings, especially "whole digits" (2), "precision" (4) and the right 

    format for the "embedded drill table units" (inches or mm).

     

    remember that the way gerber files are made are a bit 'loose', meaning 

    things like file extensions are not defined (every program uses different 

    ones) and PCB manufacturers sometimes have different idea's of what should 

    be included in what layer and in what format. So it is always wise to see 

    if your intended PCB manufacturer has an explanation of how he expects 

    things and if not, give 'm a call.

     

    That said, I've made hundred's of PCB's with different manufacturers and 

    never really had a problem. I've used GC Prevue for more than 10 years and 

    it always worked fine. As said, it sometimes only needs a little attention 

    when importing the drill file.

     

    Good luck,

     

    Richard

    Richard, thanks a lot. I spend a lot of time trying to display a single

    layer in GC Prevue (an application from hell if you are new to this),

    but did not succeed. However I found a great viewer on the web,

    GerberLogix (free for non commercial use) which is a breeze to use.

    I see that layer 3 (in Eagle), which became .L15 in the Gerber files,

    was completely wrong, no wiring. This is probably because the quad layer

    board was defined in Eagle as (123*16). Have to read more about that.

     

    Anyway, thanks for the advice.

     

    Regards, Robert
