Extract Gerber files for a 6 Layer PCB

data2008

Good evening All,

I have a BRD file regarding a 6 layer PCB. I have never extract a 6 layer PCB. I would like to do it but when i go to the CAM page, i cannot find a dedicated automatic process. I have read that i have to extract at first 4 layers and later the others 2 but i don't know how to do. Can anyone help me doing this please?

    Hi,

     

    most important - on each layer you must mark which layer is this, e.g. top, 1inner, 2inner,,,,Bot.

    this have to write on all layers of the board.

     

    Then - CAM job - your selected gerber - e.g. gbr274x.

    Then switch of all layer just the top an the pin and the via staying active.

    Then generate the first layer.

    In the menu you'll find some items like data format, see what your pcb manufacture need.

    Then uncheck top, check 1inner - generate,.... and so on.

    Then in the CAM job you have also extract the holes. For this you have also an ulp file.

    All of this you can generate in an separate folder for easily compressing the complete folder for manufacturing.

     

    This was a first global information. Please read the manual and tutorial for more and detail information.

     

    Best Regards,

    Gerald

    I can extract the drilling info without problems.

     

    After it, using the CAM jo GBR274X-4 layers, I can extract info regarding 4 layers. After it, I should select the internal layers. I an do it, but in which way I can store this information? I have to change the extension of the  files?

    No, not after. What you should do is make a copy of gerb274x-4layer.cam

    in a custom CAM folder so that you can edit it. Rename it to something

    else - I suggest gerb274x-6layer.cam - so you don't get them confused.

     

    Now, in the CAM processor, load the new copy and duplicate the two inner

    layer tabs. If you select the "layer2" tab and click on "Add" you'll get

    a second "layer2". Select that, rename it to "layer3" and edit the layer

    selection (remove 2 and add 3 instead). Also adjust the output filename

    to suit. Do the same for the "layer15" tab to make a "layer14".

     

    Now, when you run that CAM job, you will get all the Gerbers you need

    for a 6-layer board.
